Discover our pre-separators - the first filter stage to use when there’s large amounts of dust.

Husqvarna pre-separators are great supplements to your Husqvarna dust extractor for jobs that produce large amounts of dust, such as floor grinding of large areas.
A pre-separator increases the dust extractor’s capacity, protects the motor and reduces filter maintenance, allowing you to work longer without interruption.
90% of the vacuumed material is separated before it reaches the dust extractor. This includes difficult material such as soot and liquids.
Easy and clean bag change
The Longopac® bag hose system makes the bag easy to change without any dust spills.
Durable design
Corrosion-resistant steel clamps, welded frame with dust bag platform and durable steel handle make it ready to serve for many years.
Easy to transport
The welded frame enables easy transportation by resting the machine on the frame.
What is a pre-separator?
A pre-separator is a dust collection accessory that captures and stores large volumes of dust, debris, and material before they reach the dust extractor or dust collector. By intercepting heavier particles upstream, a pre-separator helps improve dust management efficiency and supports continuous operation in demanding applications such as concrete grinding, scarifying, and surface preparation.
How does a pre-separator work?
A pre-separator uses airflow separation technology to remove heavier dust and debris before they enter the primary dust collection system. By capturing most of the material at an earlier stage, the pre-separator reduces the amount of dust reaching the dust extractor, helping maintain airflow and improve overall collection performance.
Why use a pre-separator with a dust extractor?
Using a pre-separator with a dust extractor helps extend filter life, reduce maintenance requirements, and increase system productivity. By collecting the majority of dust and debris before it reaches the extractor, pre-separators help maintain consistent suction and allow operators to work longer with fewer interruptions for filter cleaning or container emptying.
What materials can a pre-separator collect?
Pre-separators are commonly used to collect concrete dust, grinding dust, shot blasting debris, scarifying waste, construction dust, and other heavy particles generated during surface preparation and concrete processing applications. They are especially effective in projects that produce large volumes of material.
Does a pre-separator improve dust collection performance?
Yes. By removing larger particles before they enter the dust extractor, a pre-separator helps reduce filter loading and maintain consistent airflow throughout the dust collection system. This can improve dust collection efficiency, reduce downtime, and help maximize equipment performance on high-production jobs.
When should I use a pre-separator?
Pre-separators are recommended for high-dust applications that generate significant amounts of concrete dust and debris, including concrete grinding, floor preparation, scarifying, shot blasting, milling, and polishing. They are particularly valuable when using dust extractors on large-scale projects where maximizing productivity and minimizing maintenance are critical.
