Product Details

The unit filters contaminants through a layer of water, which causes them to sink to the bottom. This layer of water also acts to extinguish hot particles.
Smaller particles which are not collected through the water stage are then captured in a synthetic filter.
When the water level becomes too high, the unit will self regulate, removing the excess water from the system.
When the unit fills with captured particles, all water can be drained and the unit can be emptied manually.

The GEF DPA is a uniquely designed unit which circulates the airflow in a specific way to increase the filter efficiency. This system has been designed so that the centrifugal force created within the housing separates the contaminant from the clean air, allowing the sediment and polluted particles to be collected within the water tank. The pollutant can then be disposed of easily and fresh water can be replaced to continue the filtration cycle. The DPA unit requires minimum maintenance with the only operation having to be carried out is the change of water after the sediment is removed. The DPA unit can be installed directly into the existing process to begin efficient filtration of the contaminant source, making it the ideal wet collector and a great solution for many processes.
