Jet filter QFG

Energy-optimized filter unit for larger filtrations tasks. Used for the filtration of welding smoke, grinding dust, cutting smoke and dusty air containing metal, rock, plastic etc. or from handling various powder mixes.
The filter unit is especially suitable for room extraction from process rooms, where smoke and dust occur. Optionally the unit can be equipped with various output systems, so it may be used at high dust concentrations like surface treatment and waste handling.

Product Features

  • Polluted air is led into the unit by top connection in raw air chamber. Thus securing downflow and pre-separation that minimize filter media load
  • Air is filtered through vertical filter cartridges with internal filter core for cleaning effect optimization
  • Differential pressure controlled filter cartridge cleaning through intetrated compressed-air system incl. automatic after-cleaning for optimized regeneration of filter cartridges
  • The clean air is led out through unit top connection
  • Dust is collected in dust container in unit buttom

Product Highlights

Capacities

Air volume: Up to 45,000m³/h
Vacuum: Up to 5,000Pa
Filter area: 104 - 840m²

Lower operating costs

Inlet with downflow and pre-separation as well as optimized filter cleaning ensure lower differential pressure above the filter cartridge. Therefore longer operation times with less shutdowns as well as lower operating costs (filter materials, electricity and compressed-air consumption) are achieved. One-cone version, which minimizes unit costs in connection with waste management.

Simple mounting, connection and operation

Filter unit is delivered in two modules that are assembled on the installation site by external flanges. Filter cartridges and control are delivered mounted. Compressed-air connection is easily connected on unit front. Easily accessible reading of differential pressure in digital display of filter control placed on unit service side. Filters are replaced through front door in unit side. Quicklock-adjustable dust container on 4 turnable wheels ensures user-friendly dust container service.

Filters: Cartridge filters: ø325mm. Length: 1320mm
   
Filter control: Differential pressure control type ECO-S with automatic after-cleaning 230V (constant)
  Compressed-air 5.5 - 6.0bar dry compressed air by cejn-coupling incl. ø10mm-hose nipple
  Differential pressure is visible in digital display, placed on unit at service height
  1"-jet valve connected to central compressed-air tank in clean air chamber
   
Filter replacement: Cartridge replacement made easily and dust-reduced by filter bayonet suspension that is
loosened fromclean air chamber and inserted into sack. Access by front door.
