Solution

Extraction from various decentralised extraction units from several machining processes is combined in a single vacuum filter, where reducing operating and maintenance costs was a priority. The filter has a minimum of moving parts for optimised maintenance. The vacuum filter design saves energy by ensuring that the fan always operates in clean air without dust and chips, which also minimises wear on the fan. The automatic compressed air purifying system in the filter ensures efficient cleaning of the filter bags, which reduces energy consumption. Automatic valves, combined with a frequency-controlled exhaust fan, ensure energy-efficient operation, as the air volume is always adapted to the current demand.

The ventilation unit ensures that, in colder periods, heat is recovered from the extracted air and blown into the production building. In summer operation, a bypass ensures that fresh air is led into the production building directly from the outside.
