Air is the biggest threat to the reliability of your electronics.<br />
The air in your facility contains many types of<br />
pollutants that corrode fine electronics and integrated<br />
circuits.<br />
Corrosion is the deterioration of metal due to the presence<br />
of acid gases. These gases attack edge connectors,<br />
pin connectors, IC plug-in sockets, wire-wrap connections,<br />
and other metal components. Corrosion leads to<br />
blocked currents, brittle connection points, overheated<br />
electrical systems, slowed production, and expensive<br />
equipment repairs. The end result: decreased reliability,<br />
increased maintenance, and lost revenues.<br />
<strong>Purafil</strong>'s dry-chemical systems protect capital-intensive<br />
equipment, including computer systems, compressors,<br />
switchgear, etc. against corrosive failures. For<br />
over 30 years, <strong>Purafil</strong> has been the leading manufacturer<br />
of clean air solutions for industrial facilities. We<br />
maintain nearly 20,000 installations worldwide in:<br />
• Fertilizer plants<br />
• Gas generation facilities<br />
• Oil refineries<br />
• Petrochemical plants<br />
• Pulp and paper mills<br />
• Smelting plants<br />
• Steel mills<br />
• Copper mines<br />
• Textile manufacturers<br />
• Pharmaceutical plants<br />
Our systems are housed in motor control centers, rack<br />
rooms, and central control rooms. With a single circuit<br />
board costing as much as $10,000, a dry-chemical system<br />
from <strong>Purafil</strong> saves time and money. A <strong>Purafil</strong> system<br />
also:<br />
• ensures the smooth operation of<br />
production processes<br />
• prevents lost revenue due to repairs<br />
and downtime<br />
• extends service life of sensitive<br />
electronics and instrumentation<br />
Shown on page 5, ISA Standard 71.04-1985 is the<br />
accepted guideline for warranties of electronic equipment.<br />
This standard classifies the level of airborne contamination<br />
that is safe for the reliable operation of electronics.<br />
Because <strong>Purafil</strong> designs units based on the ISA<br />
standard, our systems guarantee Class G1 air. In Class<br />
G1 environments, corrosion is not a factor in determining<br />
equipment reliability.<br />
Clean Air Guarantee<br />
<strong>Purafil</strong> has contributed to the development of ISA<br />
Standard 71.04-1985, which classifies the level of airborne<br />
contamination that is safe for electronics. As part<br />
of <strong>Purafil</strong>'s Clean Air Guarantee, industrial facilities<br />
worldwide can be assured that contaminant levels will<br />
be reduced to the target parameters established by ISA<br />
so that corrosion is NOT a factor in determining equipment<br />
reliability. A controlled space such as a control<br />
room or motor control center is designed in accordance<br />
with strict environmental criteria, to protect sensitive<br />
electronic/electrical equipment from damage caused by<br />
corrosive gases.<br />
Air Quality Standard<br />
ISA Standard 71.04-1985 titled "Environmental<br />
Equipment Conditions for Process Management and<br />
Control Systems, Airborne Contaminants," has become<br />
the accepted guide for determining the air quality in<br />
computer room environments. <strong>Purafil</strong> systems are<br />
designed to reduce contamination levels to those<br />
required for safe operation of electronic/electrical<br />
equipment.<br />
According to ISA, reactivity monitoring provides a<br />
quantitative measure of the overall corrosion potential<br />
of an environment. Reactivity monitoring involves the<br />
placement of specially prepared copper "coupons" in<br />
the operating environments. Over time, acid gases will<br />
tarnish the coupons, and corrosion films will develop.<br />
Measured in angstroms*, the rate of corrosion build up<br />
determines the environment's ISA classification (see<br />
chart on page 5). 4<br />
*(1)10 millionth of a millimeter (Å)
Air Quality Classifications Defined<br />
Mild - an environment sufficiently well<br />
controlled that corrosion is not a factor in<br />
determining equipment reliability.<br />
Moderate - an environment in which the<br />
effects of corrosion are measurable and may be<br />
a factor in determining equipment reliability.<br />
Harsh - an environment in which there is a<br />
high probability that corrosive attack will occur.<br />
These harsh levels should prompt further<br />
evaluation resulting in environmental controls<br />
or specially designed and packaged equipment.<br />
Severe - electronic/electrical equipment are<br />
not expected to survive in these environments.<br />
Environmental Monitoring<br />
Corrosion Classification Coupons<br />
Reactivity monitoring using Corrosion Classification<br />
Coupons (CCC) is a widely accepted technique used to<br />
characterize the destructive potential of an environment.<br />
Because many of the contaminants targeted for control<br />
are corrosive in nature (e.g., hydrogen sulfide and sulfur<br />
dioxide), reactivity monitors have long been used to<br />
gauge the quality of ambient air and to indicate the<br />
effectiveness of pollution control strategies. <strong>Purafil</strong>'s<br />
CCC analysis results correlate directly to ISA Standard<br />
71.04-1985.<br />
Coupon Placement: CCCs are typically employed in<br />
industrial settings to determine the effect of corrosion<br />
on sensitive electronics. Coupons are a reliable, costeffective<br />
means of classifying external and internal<br />
environments. As part of the <strong>Purafil</strong>'s monitoring strategy,<br />
individual CCCs are placed in the following areas:<br />
• Control rooms<br />
• Rack rooms<br />
• Motor control centers<br />
• Laboratories<br />
• Critical parts storage rooms<br />
• Mainframe computer rooms<br />
Laboratory Analysis: Following a period of 30 to 90<br />
days, the CCCs are collected and sent to <strong>Purafil</strong>'s laboratory.<br />
The purpose of CCC analysis is to determine the<br />
type and rate of corrosion buildup (Å/30 days). This<br />
method of reactivity monitoring has been extensively<br />
researched by Batelle Laboratories and Bell Telephone.<br />
Coupon Analysis Report: The results of <strong>Purafil</strong>'s<br />
environmental analysis are reported and made accessible<br />
to your local <strong>Purafil</strong> representative through our<br />
online Installation Tracking System, available 24 hours<br />
a day, 7 days a week. Included in the report are the general<br />
classes of gases present, estimated concentration<br />
levels, and humidity effects in your environment.<br />

OnGuard ® Corrosion Monitors<br />
<strong>Purafil</strong>'s OnGuard ® series of monitors continuously<br />
detect and transmit data in contaminant concentrations<br />
at levels as low as one part per billion. OnGuard readings<br />
also correlate to ISA's classification scheme.<br />
Unlike Corrosion Classification Coupons, OnGuard<br />
readings are real time, which allows preventive action<br />
to be taken before serious corrosion damage occurs.<br />
OnGuard Continuous Corrosion Transmitter<br />
(CCT): The OnGuard CCT logs cumulative or incremental<br />
data to detect and measure isolated corrosioncausing<br />
events and potential effects on equipment reliability.<br />
The CCT gauges in real time the amount of<br />
corrosion forming on copper and silver surfaces and<br />
transmits this information to your building management<br />
system. These measurements are directly related<br />
to ISA severity levels.<br />
OnGuard 2000 Atmospheric Corrosion Monitor:<br />
The OnGuard 2000 helps solve corrosion problems<br />
before severe damage occurs. The OnGuard 2000 continuously<br />
measures the real-time effects of corrosion as<br />
well as temperature, relative humidity, and optional differential<br />
room pressure. Using this data, the monitor<br />
projects your environment's ISA severity level and<br />
helps increase the reliability of electronic instruments.<br />
Measurements can be read directly on the monitor's<br />
LCD panel or uploaded to your personal computer or<br />
distributed control system.<br />

Design Requirements and Product Offering<br />
To design a controlled environment that will conform to<br />
ISA standards, <strong>Purafil</strong> takes into consideration proper<br />
room sealing, room pressurization, room recirculation,<br />
and humidity and temperature control.<br />
Sealing and Room Air Pressurization<br />
A controlled space must be positively sealed and pressurized<br />
to prevent the infiltration of contaminated air.<br />
Seal the space using airlock entries/exits and close all<br />
holes, cracks, wall and ceiling joints, and cable and utility<br />
penetrations. <strong>Purafil</strong> recommends a positive pressure<br />
of 0.05 to 0.1 iwg, which is achieved by introducing<br />
outdoor air through an air purification system at a rate<br />
of 1 to 3 air changes per hour (2 to 5% of the room volume<br />
per minute).<br />
Room Air Recirculation<br />
<strong>Purafil</strong> designs gas-phase air purification systems that<br />
function as either pressurization-only systems or pressurization-and-recirculation<br />
systems. Use a pressurization-only<br />
system when the space is properly sealed, the<br />
level of pedestrian traffic is minimal, contaminant concentrations<br />
are low, and negative pressure ductwork is<br />
located outside the space. The pressurization system<br />
removes gaseous contaminants from outdoor intake air<br />
and provides clean air to the protected space.<br />
In all other cases, <strong>Purafil</strong> recommends recirculation<br />
through an air purification unit at a rate of 10 to 15 air<br />
changes per hour (17 to 25% of the total room volume<br />
per minute). The recirculation system purifies air within<br />
the space to maintain the lowest corrosion levels.<br />
Environmental Control Factors<br />
Humidity: ISA S71.04-1985 recommends
<strong>Purafil</strong> Tub Scrubber System<br />
Corrosion Control Systems<br />
<strong>Purafil</strong> manufactures a broad line of gas-phase air<br />
purification systems to meet the unique requirements<br />
of each air purification application. All systems offer a<br />
customized selection of prefilter, chemical, and final<br />
filter sections. <strong>Purafil</strong> systems are grouped into two<br />
categories: self-contained systems and HVAC integrated<br />
systems.<br />
Self-Contained Systems<br />
A self-contained system consists of housing to hold<br />
<strong>Purafil</strong> gas-phase air purification media and a blower<br />
section to move the contaminated airstream through<br />
the media bed. <strong>Purafil</strong>'s offers the following self-contained<br />
systems:<br />
• Tub Scrubber System<br />
• Deep Bed Scrubber<br />
• Positive Pressurization Unit<br />
• Corrosive Air Unit<br />
HVAC Integrated Systems<br />
HVAC integrated systems offer the confidence that all<br />
parts of the air handling system will work together.<br />
Integrated systems are dependent upon the central<br />
HVAC system for operation and require space in the<br />
mechanical or machine rooms in which they can be<br />
placed.<br />
An HVAC integrated unit, the <strong>Purafil</strong> Side Access system<br />
is used to filter low to medium concentrations of<br />
outside gaseous contaminants in less polluted areas of<br />
process industries. The system can also be used for<br />
recirculation purposes to maintain low contaminant<br />
levels.<br />
<strong>Purafil</strong> Positive Pressurization Unit<br />
The Tub Scrubber System is bulk filled with media by<br />
way of fill chute openings at the top of the unit. The<br />
Deep Bed Scrubber is also a bulk-filled system but can<br />
also be tracked to house MediaPAK PK-12 disposable<br />
modules. Factory filled with the user's choice of <strong>Purafil</strong><br />
media, PK-12 modules significantly reduce maintenance<br />
and service time. <strong>Purafil</strong>'s Positive<br />
Pressurization Unit and Corrosive Air Unit are also<br />
designed to house PK-12 modules.<br />
Self-contained systems are separate from the HVAC<br />
system. They are designed for higher gas challenge<br />
levels and allow for easier retrofits, the use of standard<br />
air handlers, and less complex air balancing.<br />

<strong>Purafil</strong> MediaPAK PK-12 Module<br />
The MediaPAK PK-12 disposable plastic modules are<br />
factory filled with <strong>Purafil</strong> dry-chemical media and sent<br />
to the user ready to be installed. Constructed of highimpact<br />
polystyrene, the rigid frame eliminates the possibility<br />
of bypass air and guarantees maximum system<br />
efficiency for the life of the media.<br />
<strong>Purafil</strong>'s modular systems are tracked to house<br />
MediaPAK PK-12 modules, which significantly reduce<br />
installation and maintenance time. In fact, no tools are<br />
required for installation or replacement.<br />
The figure below shows a side view of the MediaPAK<br />
module within the <strong>Purafil</strong> Side Access System. The<br />
unique V-shaped bed of the module increases filter efficiency<br />
while reducing pressure drop.<br />

Deep Bed Scrubber (DBS)<br />
<strong>Purafil</strong>'s DBS is designed to sit outside the protected<br />
space and provide clean pressurization air to rooms<br />
equipped with electronic process control systems. The<br />
DBS is ideal for refineries, steel mills, smelters, chemical<br />
plants, petrochemical plants, and other hostile environments.<br />
The scrubber features up to four separate 12-<br />
inch-deep beds, each of which is filled from the top with<br />
<strong>Purafil</strong> dry-chemical media. Multiple media stages are<br />
required when multiple contaminant challenges are<br />
present. The OnGuard ® Continuous Corrosion<br />
Transmitter (CCT) is a standard feature on the DBS.<br />
Use the CCT to verify the cleanliness of discharge air.<br />

<strong>Purafil</strong> Tub Scrubber System<br />
Tub Scrubber System (TSS)<br />
<strong>Purafil</strong>'s TSS provides clean air in controlled<br />
environments housing sensitive computer<br />
equipment. The TSS eliminates corrosive<br />
gases typically found in industrial settings. A<br />
single three-foot deep media bed makes the<br />
TSS particularly effective in high contaminant<br />
areas. To meet your specific design<br />
requirements, <strong>Purafil</strong> offers systems for airflows<br />
from 500 to 6000 cfm.<br />
Constructed of corrosion-resistant materials,<br />
the TSS is designed for one or more years of<br />
low-maintenance service; its three-foot bed is<br />
bulk filled with <strong>Purafil</strong> dry-chemical media.<br />
Media changeout is simple and fast as the filters,<br />
blower section, and media bed are easily<br />
accessible.<br />

Positive Pressurization Unit (PPU)<br />
The PPU is a self-contained system designed to provide<br />
pressurization air that is free of corrosive gases to environments<br />
containing sensitive electronics. Designed to<br />
stand alone, it can also be used in conjunction with<br />
<strong>Purafil</strong>'s Corrosive Air Unit when pressurization and<br />
recirculation are required. Key application areas for the<br />
PPU are computer rooms, control rooms, motor control<br />
centers, and electrical equipment rooms.<br />
The PPU is available in four horizontal and four vertical<br />
configurations ranging from 500 to 4000 cfm. The<br />
flexibility of the PPU design allows for a solution to be<br />
tailored to meet your particular air filtration needs and<br />
requirements. The system is tracked to house <strong>Purafil</strong>'s<br />
disposable MediaPAK modules, which are factory<br />
filled with <strong>Purafil</strong> media and sent to the user ready to<br />
be installed. Disposable modules significantly reduce<br />
installation and maintenance time. An optional variable<br />
frequency drive can be added to achieve desired<br />
airflow.<br />

depth selection table below to calculate the depth of<br />
your unit. Actual unit depth is the sum of the depths of<br />
each filter section. This figure is rounded to the next<br />
highest inch if the total is 3/8 in (9.5 mm) or more. See<br />
the example below:<br />
For Model 2P-12M-12F-RL:<br />
Actual Unit Depth = First Section + Chemical Module Section + Final Filter Section + Rain Louver/Bird Screen<br />
45.70 in 2P = 8.00 in 12M = 18.00 in 12F = 18.00 in RL = 3.50 in<br />

Electronic Cabinet Unit (ECU)<br />
The ECU manufactured by <strong>Purafil</strong> protects freestanding<br />
electronics and electric remote controls from the<br />
damaging effects of corrosive airborne contaminants.<br />
Designed for side mounting, the ECU cleans and recirculates<br />
air within the cabinet and pressurizes the space<br />
to prevent infiltration of contaminated air. The ECU<br />
also provides localized protection of individual computers<br />
or electronic cabinets.<br />
The ECU is designed for cabinets measuring up to 100<br />
ft 3 and delivers 100 cfm (170 m 3 /hr) of clean air to the<br />
protected space. The unit comes standard with a disposable<br />
MediaPAK Module, which is factory filled<br />
with <strong>Purafil</strong>'s dry-chemical media. Replacement is<br />
easy as no special tools or handling of the media are<br />
required.<br />

Compressor Intake Filter (CIF)<br />
The CIF is a highly efficient multi-stage air purification<br />
system that removes gases and particulates to prevent<br />
corrosion. In the absence of CIF protection, these contaminants<br />
can cause reduced efficiency, costly repairs,<br />
and equipment downtime.<br />
Air moves through the CIF system in several sections,<br />
each treating the air and removing various airborne<br />
contaminants. These sections are as follows:<br />
<strong>Purafil</strong> Compressor Intake Filter<br />
Standard Features<br />
• Rain louver/bird screen<br />
• 12-24 in bag filter<br />
• 2 or 3 passes of <strong>Purafil</strong> chemical media in<br />
disposable MediaPAK modules<br />
• Plenum with mesh cone<br />
• 1 or 2 in prefilter<br />
• 5 or 12 in final filter<br />
Optional Features<br />
• 12 in HEPA filter<br />
• Booster fan<br />
Corrosion of compressor intercooler impedes<br />
heat dissipation and reduces airflow area.<br />
The first section of the process is a particulate<br />
prefilter designed to remove dust and dirt. This<br />
filter removes particulates 10 microns in diameter<br />
or greater. The primary purpose of the prefilter<br />
is to protect the chemical filters and the high<br />
efficiency final filter. The prefilter retains its<br />
structural integrity in moist environments, so it<br />
also serves as a low efficiency mist eliminator.<br />
The second section is for chemical filtration—<br />
it is where <strong>Purafil</strong> dry-chemical media is used to<br />
remove gaseous contaminants from the airstream.<br />
The CIF is tracked to house <strong>Purafil</strong>'s disposable<br />
MediaPAK modules, which are factory filled<br />
with <strong>Purafil</strong> media for easy installation and<br />
replacement. Multiple stages of media may be<br />
required to eliminate all gases of concern.<br />
The last section is the final particulate filter. This<br />
filter is a high efficiency type and removes<br />
particulates equal to or greater than 1-2 microns.<br />
The system is manufactured of weatherproofed 14 gage<br />
galvanized steel. Aluminum double wall, stainless, and<br />
cold-rolled steel may also be specified. Along with the<br />
different materials of construction, the CIF can be<br />
epoxy coated to prevent corrosion on the exterior of the<br />
unit. The chemical filtration element contains disposable<br />
MediaPAK modules.<br />

local, factory-trained representatives go the extra<br />
mile to offer the best systems and the most comprehensive<br />
services in the air filtration industry.<br />
<strong>Purafil</strong> has revolutionized the air cleaning industry.<br />
In the early 1960s, we developed and patented<br />
"<strong>Purafil</strong>" pellets to remove gaseous pollutants from<br />
the air in commercial and industrial settings. Since<br />
then, we have created a wide selection of media to<br />
eliminate thousands of gases and odors that harm<br />
people, interrupt manufacturing processes, and<br />
destroy priceless paintings and artifacts.<br />
<strong>Purafil</strong> responds to individual air quality needs<br />
before, during, and after the sale.<br />
Since no two gas-phase challenges are exactly alike,<br />
we tailor our systems to meet specific conditions in<br />
each application. Before implementing filtration systems,<br />
we perform air quality assessments to determine<br />
the best method for removing contaminants.<br />
From there, we customize units to fit virtually any<br />
room design, including retrofit situations. We install<br />
real-time air quality monitors to measure reactivity<br />
levels, and we conduct several value-added technical<br />
services to verify system performance. Our local,<br />
factory-trained representatives examine systems to<br />
ensure proper maintenance and foster long-term customer<br />
relationships.<br />
<strong>Purafil</strong> has paved the way in the gas-phase filtration<br />
industry for over 30 years.<br />
As a leader in air purification, we have the responsibility<br />
to set standards and conduct research. We play an<br />
active role in devising contamination control regulations<br />
in the markets we serve. Our scientists head committees,<br />
attend scientific forums in various countries,<br />
and submit articles to international trade journals. We<br />
are supported by an expansive network of representative<br />
firms in the United States and over 50 countries<br />
worldwide. Our collective expertise and intense focus<br />
are the reasons <strong>Purafil</strong> continues to lead the industry in<br />
the development of superior clean air solutions.<br />
<strong>Purafil</strong> takes every step necessary to provide quality<br />
systems.<br />
Because we manufacture and test our products at company<br />
headquarters, we have extensive proficiency with<br />
our systems. We are ISO 9001/2000 certified, so we<br />
follow rigid guidelines to continually improve our<br />
products and services. To meet and exceed our high<br />
standards, we spend a large percentage of annual revenue<br />
on research and development.<br />
<strong>Purafil</strong> has been widely recognized for innovative<br />
air filtration systems.<br />
We have received extensive coverage from local,<br />
national, and international media. We are the proud<br />
recipient of several prestigious awards, including the<br />
U.S. Presidential "E" and "E Star" awards for commerce,<br />
the Fast Tech 50 Award, the World Trade 100,<br />
