The Absolent A•Smoke 40 Oil Smoke Filter features one of the most effective systems in the world for cleaning oil mist and oil smoke. The unit requires very little service: it can run for 1–6 years without requiring a filter change - translating into extremely low life cycle costs. The A•Smoke 40 is designed for handling the most demanding applications, for air flows of up to 4000m³/h.
The filtering process occurs in three stages. The process air passes first through a self-draining Absolent filter cassette where a large portion of oil mist and smoke is arrested. When the filter is saturated, the liquid drops into the return oil tank. The air continues through another Absolent filter, where remaining particles are arrested. The third stage consists of a HEPA filter, which has a guaranteed and consistent collecting efficiency of 99.97% arresting 0.3µm dia. particles. Every filter stage has a pressure gauge that indicates when a filter change is necessary.
Thanks to the continuous draining of the filter cassettes, the unit can be operated without interruptions. The return oil is collected at the bottom of the filter for recycling.
