Mechanical Vacuum Pumps contain devices such as pistons, claws, scrolling spirals, and diaphragms to isolate and compress air. They are most efficient in the rough and medium vacuum ranges, but lose efficiency at high and ultrahigh vacuum levels. The mechanical pumps and systems are mostly powered by compressed air. The common AC single-phase voltages are 115 V (60 Hz) and 230 V (50 Hz) and AC three-phase voltages are 208 V and 377 V. Engine-powered mechanical vacuum pumps and systems use gasoline or diesel engines.
Mobile mechanical welding smoke filter offers many advantages for use at changing welding workstations. This filter is available in various lengths such as 7.0 ft., 10.0 ft. and 14.0 ft. The extracted air is first fed into a pre-filter where large particles are captured, then through a main filter where the welding smoke is cleaned with a filter efficiency rating above 99.9 %. This means that even the smallest particles down to a size of 0.3 micron are filtered.
Stationery mechanical welding smoke filter is ideally suited for use at fixed welding workstations, in welding cabins and training workshops. The extracted air is first fed into a pre-filter where large airborne particles are captured. Then the air is brought through the main filter, where the welding smoke is cleaned with a filter efficiency rating above 99.9 %. This means that even the smallest particles down to a size of 0.3 micron are filtered.
