Various configurations

FilterScheiding
Fine particles (green) – Air flow around deflector
X
The air with the finer dust particles is distributed in the dust space and is sucked in from the outside, through the filter cartridges, so that the dust is separated. The cartridges are cleaned by means of compressed air shocks
Baffle plate – Separation of coarse particles
X
The unit is equipped with integrated pre-separators The dirty air first encounters this baffle plate. Heavier particles cannot damage the filter cartridges thanks to the protection provided by the baffle plate. The coarse dust is directly collected in the dust collecting funnel. Without the baffle plate, heavier particles would directly attack the filter media, increasing wear.

Unique features
  • Integrated pre-separator
  • Integrated compartment for compressed air cleaning, reducing noise emission
  • Adjustable pulsing to reduce cost
  • Easy and quick replacement of cartridges
  • Ultra efficient fans that minimise power requirements and reduce power consumption
Basics of airflow

An airspeed of for instance 20 m/s is normal for steel particles, where the airspeed in the filter compartment is reduced to below 1 m/s.

Methods for dust collection

Retaining frame

ATEX / Explosion proof in combination with ATEX blockage indicator in the funnel. Frame pushes waste drum up against filter.

Big Bag

Holds large volume of dust and can be placed on a pallet for easy disposal. (Possibility of ATEX including earthing)

Plastic bag

Directly attached under conical valve and easy and quick to attach with clamp ring.
