DRAGON VAC 200 belongs to the high-vacuum filtering unit group. It is designed for extraction and filtration of viscous welding dusts, that arise during the welding of oil-laden steel sheets or while using anti-spatter-sprays in high amounts. It is a perfect solution for fume extraction from the welding torches with an integrated extraction system. Additionally, the appliance can be connected to the welding faceshields with extraction or to other miniature local exhausts. The basic equipment of this device type is a suction turbine of high vacuum and a compact filter manufactured on the basis of a waterproof cardboard of glass-fibre.
