HIGH-VACUUM EXTRACTION AND FILTER DEVICE FOR WELDING FUMES

SRF SK

Continuous-running for low to medium fume volumes.

The high vacuum welding fume filters of the SRF SK series can be used to extract from multiple welding torches at the same time via a connected pipe. The high negative pressure guarantees optimum suction force, even at larger distances. Thanks to the side channel blower acting as a suction unit, devices can also be used in uninterrupted operation. SRF SK models are in four power ratings.
