The combination is - compressor for the generation of compressed air, as well as negative pressure for use as a dust - and wet aspirator

摘要

The compressor (1) is connected to a removable dust or liquid collection container (3) via the protective plate (18) of a fan wheel (5) which generates sufficient suction force so that the cool air for the compressor serves as the suction air for the removable collector. A three-way ball valve (10) closes a pressure equalisation line (10a) when switched over to suction mode, and simultaneously taps off the compressed air in the compressor cylinder. The pressure drop switches on the compressor's pressure switch (11) and the suction process can begin.
