Holzprofi Automatic Switch for Extraction System - Three-Phase Combination

Our automatic switch for extraction systems makes working in your workshop even more practical and convenient. The extraction system starts automatically, eliminating the need to manually turn it on. This means less dust and dirt, providing you with a more pleasant and cleaner working environment. The automatic switch ensures that the extraction system activates approximately 3 seconds after the machine starts. This guarantees that dust and chips are immediately extracted without overloading the machine. After the machine is switched off, the extraction system remains active for another 8 seconds to remove all remaining particles.
