The Multi C²Air is suitable for most welding processes and filters gases, vapors and dust particles. The air flow is electronically controlled and is therefore always constant and can be set to both 160 and 200 l/min. The eMulti C²Air has a secured on/off switch and warns of reduced filtering by an acoustic signal, a light signal and a vibration signal. The Multi C²Air is one of the lightest motor units on the market and this, together with the ergonomic lumbar support, ensures high wearing comfort. The Multi C²Air comes with an interchangeable li-ion battery with a capacity of up to 8 hours, an air hose with flame-retardant cover, two P(SL) filters, a battery charger, a flow meter and shoulder straps.
