Handte Venturi

The wet scrubber Handte Venturi is the recommended solution to remove fine particles with high dust loads from the raw gas stream extracted from industrial applications, even from those with higher temperatures. This can be flamable or explosive dusts from processing metal, steel, aluminium, magnesium or titanium as well as sticky powder or greasy vapours.

  • For applications with ultrafine particle dimensions and high dust loads
  • Separation efficiency adjustable on grain size distribution and particles density
  • Optimum separation due to water injection in the Venturi zone
  • No fan power limitation
  • Excellent accessibility facilitates easy maintenance
  • Automatic sludge scraper upgradable


The Venturi wet scrubber provides best separation efficiency on fine explosive metal dusts with high dust loads. This kind of dusts usually occur in industrial metal processing applications like shot blasting, grinding, brushing, hardening, forming, deburring or fettling.
Functional principle of the Handte Venturi wet scrubber:
In the upstream Venturi zone, the scrubbing water is injected into the exhaust airflow, disrupted by the increase in velocity of the air, and disintegrated into water droplets. The high velocity between the polluted exhaust air and the water droplets in the Venturi throat causes the pollutants to bind with the water droplets. The polluted exhaust air is introduced tangentially with the polluted scrubbing water to the downstream demister unit and separated by the active centrifugal forces. The purified exhaust air is moved and discharged by the downstream ventilator positioned on the clean gas side. The separated pollutants are fully or partially isolated in the collecting area of the scrubbing water through sedimentation processes. They can be disposed of using various discharge systems.

Considerations when selecting an equipment supplier for extraction systems

The potential for a combustible dust explosion is a reality in any industrial manufacturing facility. But operations with processes that generate combustible metal dusts are especially at risk and require special consideration when selecting an equipment supplier. Camfil´s new eBook lists seven important considerations for determining whether a dust collector equipment supplier has the knowledge necessary to keep your operation safe and compliant.
