4,000 ft3 /min. | A Healthy Solution for Clean Air

The Air-Vac M40 comes standard with 2hp belt driven motor which produces 4000Cfm. Upgrade to the M-45 and get a hefty 4500cfm utilizing our 3hp configuration. The M-40 Series is self-contained for use individually or in groups. It is intended for use in large buildings or industrial plans without exhausting or duct work required. Each M-40 series is hand built in USA with industrial grade components housed in a heavy-duty 16 gauge steel cabinet and finished with chemical resistant powder coat paint.

The Air-Vac M-40 series reduces the make-up air requirements up to 80% without any heat or A/C loss. Energy cost savings alone make your Air-Vac air cleaning system an attractive investment for small operations or large multi-unit installations.

Both the M-40 and M-45 can be manufactured in a horizontal or vertical configuration to better fit your space’s needs.

How It Works

First, dirty air is pulled through filter intakes at each end of the M-40 series consisting of multiple four inch thick pre-filters to catch the large particles.

The second stage filtration process is multiple industrial grade 22 inch deep, 95% efficient bag filters which traps submicron particles that get through the pre-filter. The clean air is then exhausted back into the building through the center of the M-40.
