Usage & Benefits

Hi-Vac 400 Series portable industrial vacuum systems offer additional filtration for higher horsepower applications. The 450 and 475 models move dry material, wet material or liquids through up to 900 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 with a patented 3 Stage Filtration System including a primary centrifugal separator which spins the air, causing most of the material to drop out of the air stream into the end dump hopper below. Air then moves through a secondary 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 15 envelope-style filter bags before moving into the vacuum producer and out into the atmosphere through an exhaust air silencer. The 400 Series portable industrial vacuum systems are equipped with easy-to-use controls and instrumentation for operation and monitoring performance to protect critical components.

400 Series portable industrial vacuum systems feature: Heavy-duty construction 3/16” steel plate, envelope-style filter bags offer lower air-to-cloth ratio resulting in longer filter life and lower cost, Standard Blower Protection Package: broken bag detector, lower blower oil notice, high temperature safety shutdowns, PLC controller monitors system operations: should any shutdowns occur, maintenance personnel can quickly locate the problem, wet/dry material clean-up capabilities, positive displacement-type vacuum pump produces a vacuum of 18” Hg.
