Mobile welding fume purifier equipment generally occupies a small space, and has various forms such as movable and fixed. It is very flexible to choose according to needs. PURE-AIR also produces various welding fume vacuum cleaners in large quantities, especially the mobile single, vacuum dust collector, and dual-arm welding fume vacuum cleaners, which are all the fume purification equipment that enterprises need urgently. Today PURE-AIR discusses three types of suction hoods commonly used in welding fume vacuum cleaners.

When choosing a welding fume hood for vacuuming, pay attention to the following matters!

The inlet hood of the mobile welding fume purifier and the vacuum nail dust collector should be as close as possible to the source of pollution.

Generally speaking, the suction hood of the welding fume vacuum cleaner should be as close as possible to the source of pollution without affecting the technical operation, and try to avoid drying with horizontal airflow.

Flange edges should be installed around the exhaust hood of the welding fume cleaner.

Adding a flanged edge around the exhaust pipe reduces the amount of exhaust. The flange width is generally between 150 and 200 mm.

The expansion angle of the dust collecting hood of the mobile welding fume purifier has a great influence on the velocity distribution of the hood and the pressure drop in the hood.

The expansion angle of the outer air collecting hood of the wave soldering smoke extractor is 30~60°. When the pressure loss is small, the expansion angle a should be less than (or equal to) 60°; when the expansion angle is large and it is difficult to meet the above requirements, it should be Take measures such as increasing suction.
