The HERR Wolf central high vacuum filter system is your first choice if you have to connect more than three torches. Same as the mobile Wolf it uses HISTec®ePTFE filter cartridges in combination with the HiRoto®H-type rotary back flush nozzle. Two cartridges of 10 m² each ensure an efficient cleaning (99.9%) of particulate matter ≥0.1μ. Cleaning is automated and can be executed during operation. Depending on your application the Wolf high vacuum system can be configured to connect up to 20 welding torches.
