The GAS 35 H AFC Professional is the high-performance wet/dry dust extractor enabling better user protection. Its safety filter traps 99.995% of health-endangering dusts. The certification for H-class dust further increases the level of health protection against carcinogenic and pathogenic dust as well as organic material (e.g., mould) and container construction material (e.g.,glass fibre). Its automatic filter cleaning mechanism prevents interruptions for constant working. A volume flow control monitors the constant air flow through the suction cup and gives an acoustic warning signal if the air flow is too low.
