More info

HJL series bag filters are made of S275JR steel in thicknesses suited to working with high dust loads for external installation and 24h/day operation.
The Ø125mm filtering bags, available in lengths varying from 2500mm to 4500mm, are equipped with reinforced bottom and Snap-Ring fastening system. The fibre making up the bag is chosen based on the application. The bags are held in position by cut-proof, break-proof galvanised steel bag tensioning baskets. The bags and baskets can be removed from the walkable filter roof.
HJL series bag filters are equipped with a counter-current Pulse-Jet compressed air cleaning system. This is mainly made up by a compressed air tank, PED certified according to the 2014/68/EU standard, equipped with pre-wired “Full Immersion” membrane valve with BUS management system and electronic control unit installed on the filter for automatic cleaning based on when the bags are clogged. To optimise cleaning system efficiency, Venturi nozzles can be installed on each bag.
The bag filter dust discharge system is made up by a collector auger at the bottom of the hopper and sealed rotary feeder to unload in Big-Bags.
The following can be supplied as accessories:

  • broken bag alarm instruments,
  • level sensors for hopper clog alarm,
  • rotation sensors for dust discharge system

Versions

HJL series Atex Version bag filters

All the bags are connected to the earthing line to prevent static electricity from accumulating and reduce the risk of sparking an explosion.
