The Zero Smog 20T is designed for direct extraction at the soldering iron. Up to 6 WELLER FE soldering irons can be connected directly. Indirectly, via the pipe system 50 available as an accessory, up to 20 FE soldering irons. The powerful, maintenance-free turbine generates a vacuum of max. 10,000 Pa and is electronically controlled. The operating hours and the level of filter contamination are also recorded electronically. The filter system achieves a separation efficiency of 99.95 % in accordance with EN 1822 at a particle size of 0.16 ? m. - Mobile device with four castors for centralized or decentralized use - Use with a pipe system of up to 200 m - Electronically controlled and maintenance-free turbine generates the required negative pressure - Up to 20 soldering irons can be connected - 1 extraction unit - 1 compact filter - 1 fine dust filter F7
