The welding fume dust collector is sucked into the air inlet of the equipment through the universal dust suction hood through the gravity of the fan. The air inlet of the equipment is equipped with a flame arrester. The spark is blocked by the flame arrester, and the smoke gas enters the settling chamber.Harnessing gravity and updrafts. Airflow, firstly, the coarse dust is directly dropped to the ash hopper, and the particulate dust is captured by the filter element on the outer surface. After the clean air is purified by the core-to-filter, it flows into the clean room from the center of the filter element, and the clean air is further purified by the adsorption of the activated carbon filter. Discharged through the air outlet. The main components include: universal vacuum arm, high temperature resistant vacuum hose, vacuum hood (with air volume regulating valve), fire retardant net, flame retardant filter element, pulse blowback device, pulse solenoid valve, differential pressure gauge, clean room , activated carbon filter, ash drawer combination, flame retardant and sound-absorbing cotton, new Korean casters with brakes, fan, ABB motor and electric control box, etc.

The suction arm can be rotated arbitrarily 360 degrees, hovering and fixed at any time. Two-stage filtration. Scientific fan design, large air volume and low power consumption. Filtration accuracy up to 0.3um. With fully automatic pulse control dust removal function. The filter efficiency of the purifier reaches 99.9%. With shutdown manual cleaning function. Adopt protection device to prevent motor overcurrent and overload. The standard suction arm length is 2 meters, and the non-standard length is 3/4 meters.
