Rigid Pocket Filter PFL
DESCRIPTION
Vira Safi use thermally bonded synthetic media for their PFL
rigid pocket filter. The depth-loading media is manufactured in
a progressive density multi-layering technique to ensure high
dust holding capacity with lowest pressure drop. For the user,
this results in long filter life and low energy and maintenance
costs. The pocket filter medium is inherently rigid, with a welded
rib construction to form a pocket with the higest possible function
security in even the most brutal air pressure and high dustladen
environments.
PFL, rigid pocket filter are metal free an thus do not corrode,
can be incinerated and withstand 100% humidity environments
with ease.
Aerodynamic wedge-shape, tubular pocket spacers, minimum
air flow resistance, maximum turbine output.
Pockets integrated in injection moulded, impact-proof combine
ABS and PU header, gives filter a burst strength of < 6000 Pa.
Unique proprietary Vira Safi medium, providing maximum dust
holding capacity.
For all types of environments: high dust, moisture and water mist
contentas well as high velocity.
Self supporting, leak-free welded pockets, stay rigid in turbulent
airstreams, eliminate shedding.
Vira Safi PFL filter may be disposed of by incineration.
