Dedusting systems

The deduster sits inside an air circuit. Choose closed or open loop, and the dust collector that suits your material.

One blower serves both cleaning air and exhaust
Dust after cleaning down to ≤50 ppm
For higher dust content in the raw material (below 2%) and large throughput, with automatic cleaning of the bags
Suits all gas-tight systems, especially nitrogen-blanketed lines
Suits toxic or hygiene-critical duties and moisture-sensitive materials
Modular, easy to maintain, low energy use

Cleaning air and exhaust use two separate blowers
Dust after cleaning down to ≤50 ppm
Excellent for low dust content and smaller throughput
Airflow controlled by a damper or VFD on the supply blower outlet, or by the air-inlet on the suction side
Better airflow control when the dust collector is far from the deduster

Which one fits?

	Closed loop	Open loop
Blowers	One	Two (supply + exhaust)
Best for	Gas-tight or nitrogen-blanketed lines, toxic or hygienic duties, moisture-sensitive materials	Long distance between deduster and dust collector; tighter airflow control
Cyclone + inline filter	Raw material with low dust (below 500 ppm) and smaller throughput
Bag filter	Higher dust content (below 2%) and large throughput, with automatic bag cleaning
