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.
