Dust Stop – bulk material dust suppressor
Why so much dust?
Every time bulk material is loaded or unloaded, dust is created. The patented Dust Stop concentrates it inside the falling product and makes an additional aspiration system unnecessary.

The challenge
A familiar problem, solved mechanically
Dust clouds during loading are no minor issue: they cost product and put a strain on the environment and equipment. The Dust Stop acts exactly where the product falls.
The problem
Uncontrolled dust formation
As bulk material falls freely, fine dust is stirred up and spread into the surroundings, clearly visible on the vehicle, the building and the area around it.
The solution
Dust Stop in operation
The dust is concentrated in the core of the falling product stream and falls together with the product, with no additional extraction at all.
Operating principle
How the Dust Stop binds dust as it falls
The dust suppressor can be used for any loading or unloading process with heavy dust formation, which means aspiration systems are no longer required. The patented operating principle concentrates the dust inside the falling product and thus minimises it purely mechanically, without filters, power or maintenance.
- The funnel shape guides the product stream towards the centre
- Dust collects in the core of the stream instead of spreading sideways
- Dust and product leave the Dust Stop together, no separate exhaust system needed

A = automatic (DS‑A) · M = manual (DS‑M)
Available in two versions
DS‑A or DS‑M, depending on the application
Both versions are based on the same mechanical principle. The difference lies in how the falling stream is controlled.
Automatic
DS‑A
For products with different specific weights, the falling stream is regulated automatically by an electrical control system.
Optical sensors · Pneumatic slide gate · Control cabinet
Manual
DS‑M
For the same product with several loading points, the falling stream is set manually.
Simple mechanical adjustment
Frequently asked questions about the Dust Stop
What is the Dust Stop?
The Dust Stop is a patented bulk material dust suppressor by Wagner Feedmill. It is installed at the loading point and binds the dust created when bulk material is loaded or unloaded within the falling product stream.
How does the Dust Stop work?
The funnel shape guides the product stream towards the centre. The dust collects in the core of the falling stream instead of spreading sideways and leaves the Dust Stop together with the product.
Is an additional aspiration system required?
No. Because the dust stays in the product stream, no additional aspiration or exhaust system is needed. A filter connection is included as standard.
Which sizes and capacities are available?
There are five sizes: DS 40 (45 m³/h), DS 60 (128 m³/h), DS 75 (256 m³/h), DS 100 (385 m³/h) and DS 150 (641 m³/h).
What is the difference between DS-A and DS-M?
On the DS-A, an electrical control system with optical sensors, a pneumatic slide gate and a control cabinet regulates the falling stream automatically. This suits products with different specific weights. The DS-M is set manually and suits the same product at several loading points. Both versions have identical dimensions.
What material is the Dust Stop made of?
Painted steel as standard. Stainless steel or HARDOX are available as options.
