Operating principle
Dust is extracted from various areas of the foundry and separated in the two filters. The two filters are set up in parallel and allow flexible operation; we can also run filters individually via the butterfly valves. The two centrifugal blowers are equipped with soundproof booths to ensure a maximum sound pressure level of 70 dB(A). The cleaned exhaust air is passed through heat exchangers to preheat the fresh air supply to the foundry shop. The exhaust air is then led outdoors via a chimney. Dust collection trays including discharge screws are insulated and heated.
