Advance in filter bags

Flextraction, supplier and
manufacturer of Local Exhaust
Ventilation (LEV) products, has
designed a new low cost, multicompartment
filter bag with a
folded construction labyrinth. This
is designed to fit into existing laser
and solder fume extractors being
used on laser, solder and other
industrial fume and dust extraction
applications.

The design is said to be a major
advance on existing designs with
increased filtration surface area, F8
classification to BS En779:2002
standard and a 75% reduction in
stitched seam length. This reduces
the cost of manufacture and also
the potential for leakage through
the seams.
