MATRIX-1000-W is applied for cleaning the air from dry welding dust arising at the mobile workplaces. Maximum temperature of the forwarded air is +60°C. Due to the applied cartridge filter, the dust particles are separated on the filter outer surface. Subsequently, by means of impulses of compressed air, the contamination is struck off from the filter surface. MATRIX-1000-W-1 is designed for work with one extraction arm, whereas MATRIX-1000 W-2 with two extraction arms. In the second case, the MATRIX-1000-W should be used for low charged workplaces, due to double-reduced flow capacity distributed from one extraction arm.
