Series HKDSF
Low-Pressure Fan (Dust Aspirator)
The low-pressure fan draws dust from machines and conveyors and delivers the collected air to a cyclone or filter line.

The dust aspirator is the air source for the point-extraction lines inside the mill. It is selected to deliver a high volume at low pressure, which matches the typical resistance of aspiration ducting.
A scroll housing, a backward-curved impeller and a balanced rotor give low noise and long bearing life. Inlet and outlet are flanged and connect easily to existing ductwork.
Air volume, static pressure, motor rating and dimensions are given in the model table. The fan is installed on vibration pads.
Key features
- High-volume, low-pressure characteristic
- Balanced backward-curved impeller
- Flanged inlet and outlet
- Mounted on vibration pads
- Selection matched to cyclone and filter lines
Applications
- Point extraction from machines and conveyors

How it works
Working principle
Conveying moves grain and milled products between every stage of the plant with minimal energy and no product damage.
- 1Product enters the boot of the elevator from a conveyor or hopper.
- 2Buckets on an endless belt lift it up the loaded leg and over the head pulley.
- 3Centrifugal force throws the product into the discharge spout, from where screw or chain conveyors and pneumatic lines carry it on.
