The stationary welding fume filters of the MOBEX F series are designed for effective extraction of welding fumes. The devices mostly come into use in the metal industry for single and multiple workstation extraction. Up to four extraction sites can be operated at the same time via a pipe system. The MOBEX F series is based on a new housing concept with a patent-pending folding system. It is optionally available with the IFA inspection certificate W3 for high-alloy steels.
