ESTA Extraction
New wet separator for use during grinding, brushing and polishing



The new wet separators of the DUSTOMAT HYDRO series are ideal for work processes with flying sparks, as well as for the extraction of highly flammable substances. Even welding fumes can be effectively separated with the DUSTOMAT HYDRO. Thanks to innovative water separation technology, the extracted materials are safely bound in water, in contrast to a usual dry process, and can be discharged via a drain cock. The extracted air then runs through a multi-stage filter system, which is configured according to the application. The highly effective HEPA H 14 filter (separation efficiency > 99.995 %) is particularly suitable for filtering hazardous dusts, which means that the cleaned air can then be returned to the room.

The compact wet filter units are suitable for single and multi-station extraction, for example for metallic dusts, especially in grinding, brushing and polishing processes as well as welding. The DUSTOMAT HYDRO wet separators are particularly quiet in operation and are available in four performance levels.

Innovative water separation technology

The wet separators of the DUSTOMAT HYDRO series feature an innovative water separation technology: The system is based on a hydrocyclone system and makes sparks as well as inflammable dusts almost completely harmless already in the first filter stage with a separation efficiency of 98.7 %. Even the smallest particle fractions of ≥ 15 µm are safely bound in water vortex chambers. ESTA thus raises the quality of pre-separation to a new level. Users benefit from a significant effect: The filter media of the subsequent dry separation system are protected, resulting in longer service life and low follow-up costs.

In contrast to conventional wet separators, which often have a fixed multi-stage filter system, the DUSTOMAT HYDRO wet separators can be equipped with a dry filter package oriented to individual requirements with separation efficiencies of up to 99.995 %.
