Usage & Benefits

Hi-Vac 300 Series industrial vacuum loaders are a more economical choice when high horsepower is not required. The 320 Model industrial vacuum loaders move dry material, wet material or liquids through up to 200 feet of vacuum hose or a Hi-Vac designed in-plant piping system using a powerful 18” Hg vacuum producer. Material is separated from the air stream using a more compact version of our patented 3 Stage Filtration System, including a primary centrifugal separator that spins the air, causing most of the material to drop out of the air stream into the end dump hopper below. The air stream then moves up through a vertical column, including an integrated linear separator, which causes the air stream to speed up and change direction, dropping smaller fines and entrained moisture into the hopper. Finally, the air stream enters the dust collector housing where it passes through a reverse pulse continuous cleaning baghouse and out into the atmosphere through an exhaust air silencer.

300 Series industrial vacuum loaders feature: Heavy-duty construction 3/16” steel plate, smaller overall footprint for compact spaces, envelope-style filter bags offer lower air-to-cloth ratio resulting in longer filter life and lower cost, wet/dry material clean up capabilities, positive displacement-type vacuum pump produces a vacuum of 18” Hg. Continuous reverse pulse cartridge filtration arrangement also is available.
