The DUSTMAC F series is used for simultaneous welding fume extraction in multiple work stations. The optional impact separator in the pipe intake ensures even air distribution in the filter chamber and reduces the risk of fire caused by sparks being sucked in. Thanks to its modular construction, the installation can also be extended later. DUSTMAC F-series filter cartridges can be cleaned inexpensively using ESTA ultra-sound filter cleaning whilst protecting the cartridge.
