The  Mikro  - Pulsaire  bag  filter  consists  of  filter  cylinders (bags)
   enclosed in a metal housing in operation, dust laden  air  enters  the
   collector  housing through the hopper inlet in the storage - discharge
   hopper. Either pressing  or suction  delivers  in  the  dirty  air  to  the
   hopper. The fine particles travel upward and collect on the filter bags.

   The  clean   air   passes   through   the  bag  and  is  vented  to   the
   atmosphere. A high pressure jet of compressed air directed  through
   the  bag  at  timed intervals  removes the dust, which is deopsited in
   the hopper and is easily  collected  for  disposal or recovered for use.
