WIBOjekt ® economy safety workboxes for
protection of personnel and the environment

WIBOjekt® economy
Our expertise – your safe decision
The progress being made in the fields of industry and science poses increasingly
tough demands in terms of protecting personnel and the surrounding
room against pollutants.
Workstations and installations at which hazards can arise must meet certain
requirements which are both functionally and economically critical.
During the last few decades, Weiss GWE has established itself as a competent
and flexible partner in this segment for industry, technology and
laboratory users.
As a company in the international Schunk Group, we work closely with
customers to develop efficient, individual and cost-effective solutions.
Continuous support from our professional service department helps to
ensure that the equipment can be used in a cost-effective manner and
that the value of the investment is retained.
The WIBOjekt® air guidance principle
The WIBOjekt® principle
Units employing the WIBO-jekt® air
guiding principle create a stable
clean-air curtain. This is generated
by a combination of specially
shaped and configured air outlets
(so-called ejectors) and stabilisers.
The ejectors target contaminants
(such as gases or airborne product
dust), collecting and conveying
them to the exhaust system. The
clean-air curtain ensures optimum
protection of personnel
and the vicinity, safeguarding
both personnel and the surroundings
against emissions generated
by the product.
The WIBO ejectors are accurately
matched in terms of design, shape,
direction, speed and the air volume
they can handle. This perfect interaction
allows an optimum flow
pattern to be established to suit
prevailing requirements. The cleanair
curtain even remains almost
completely intact when personnel
working on the unit reach through
the curtain to the inside of the
box. This ensures that the system
continues to capture any harmful
pollutants and emissions which
are released.
2
Despite the superior quality capturing
and extraction performance,
plants fitted with the WIBOjekt®
system require significantly less
exhaust air than comparable conventional
extraction systems.
Costs for operation are thus
reduced substantially.
The WIBOjekt® economy safety
workboxes from Weiss GWE are
available in three different designs.
The EL, EB and EV designs differ in
terms of equipment – i.e. with or
without a sliding front shutter – as
well as in terms of how individual
systems can be combined with
other individual systems to form a
larger system.

Individual components and accessories
Front shutter according to EN 14175 for
the EB type safety workbox
The safety workbox economy N2 (width = 1,200, 1,500, 1,800)
can be retrofitted with a front shutter in accordance with
EN 14175.
■ Front shutter with a variable working opening of 500 mm max. A
limiter for the front shutter needs to be deliberately released in order
to enable a larger opening height of 800 mm max.
■ The panes are made of 6 mm laminated safety glass and consist of 2
or 3 parts which can be pushed together to form a packet. The pakket
acts as body and splash protection.
■ Smallest packet width: Width = 1,200 (2-part) => 480 mm
Width = 1,500 (3-part) => 430 mm
Width = 1,800 (3-part) => 430 mm
■ At a width of 1,800 mm, a fixed pane of laminated safety glass with
a width 150 mm is used on both the left and right-hand side in order
to keep the body protection packet at 430 mm.
Stand holder
■ The stand holder is positioned in front of the rear panel.
■ The individual rods of the stand (Ø 12 mm) can be easily inserted and
removed at a distance of 150 mm as required. Further setup using
commercially available clamps and mountings.
■ The mounting rails for the stand can also be used to mount other
mounting systems.
■ The lower cone on the rod provides purchase and prevents twisting
of the setup. Additional clamp holders are available on request.
Worktops
■ A wide variety of differently designed worktops can be placed and
sealed on the worktop mountings.
■ Sturdy ceramic worktop, white, mounted on carrier plate
■ Waterproof chipboard with plastic coating
■ Stainless steel (1.4301) worktop with internal core made of waterproof
chipboard
■ Sturdy ceramic top compliant with DIN 12916, T1
■ Special designs are available for virtually any quality requirements,
partitioning and installations.
