Cartridge | FiltrationNatural Filtration | Algaeoffering longer service life. In addition,CFE can be used in difficult environmentsand industrial processes savingenergy and operational costs.Figure 2: CFE technology can reduce filter housing volume by 70% and operatingcosts by 40% in comparison to filter bags and filter sleeves.The main features and benefits ofCFE are:• Up to 3 times more filter areacompared to conventionalfilter bags• Can reduce filter house volume byup to 70% (see Figure 2) saving upto 40% on running and energycosts• High efficiency – in most plantslower than 1mg/Nm 3 emissions(0.0004 grains per scfm)• Long service life (circa 3-5 years)• Excellent cake removal achievedwith reverse pulse cleaning• Simple, quick and clean to installand replace• Can be retrofitted into existingunits• CFE are more compact, makingindoor installations possibleDepending on the application, ClearEdge can customize the filter elementswith different finishes, e.g., oleo- andhydrophobic, temperature resistant,microporous coated, PTFE-membranesurface, antistatic, and many more.Clear Edge has many years of experiencedesigning and using CFE – typicalapplications include:• Welding fumes especially in lasercutting in high purityenvironments• Automotive including paint shopspraying• Construction and mining, i.e.,tunneling• Milling, especially powderhandlingDuring the last 22 years, Clear Edgecustomers have installed thousands offilter elements over the world coveringpractically all industrial de-dusting applications.In conclusion, CFE are an alternativeto bags and traditional cartridgesespecially where space or height is at apremium. Due to the unique design,CFE can be cleaned and maintainedmore easily than traditional cartridges,18 • August 2013 • www.filtnews.comCERAFIL – HOT GAS FILTERSCerafil, from Clear Edge, is afamily of low-density ceramic filter elements,which are employed in filterplants in much the same way as filterbags except at much higher temperatures.Typically, Cerafil is used in therange from 200 - 800°C (392-1,472˚F), thereby avoiding acid andwater dew points and allowing for applicationat the temperature that bestsuits the duty. In addition, Cerafil elementsare extremely efficient andcorrosion resistant and can be used inthe most difficult gaseous conditions.Developed over a number of years,Cerafil is a monolithic low-density ceramicelement, which is highly effectiveand efficient at handlingsub-micron particles in industrial gasprocesses. The product family has beenexpanded to three specific productlines, which are available in a range ofsizes up to 3m (10ft.) in length and150mm (6”) diameter.The applications of this “Best AvailableTechnology” include Air PollutionControl (APC), Product Collection andProduct Recovery. The one-piece elementis self-supporting and robust in avariety of conditions, has long in servicelife and is highly porous and futureproofed for forthcoming tighter environmentallegislation (capable of filteringgas
