The MAC-21VFD is a modular ventilation unit capable of providing High Efficiency Particulate Air (HEPA) filtration with 99.97% efficiency @ 0.3 microns.
The MAC-21VFD is an assembly of three modules:
1) Power Module– a direct drive blower/motor and base assembly;
2) Filter Module- prefilter & HEPA filter housing assembly;
3) Quick-mount handling cart and mounting platform for the power module and filter module.
This unit has been evaluated to the applicable CSA standards for use in the United States under product Class 3812-81 (US – Fans and Blowers). Please call for information on VFD units that are CSA approved for use in Canada.
The model MAC-21D (P/N FM41) is an adaptation of our model MAC-21 (P/N FM37) 500 CFM HEPA unit. This unit gives up some of the “modular features” in favor of a design assembled from explosion-proof components. The MAC-21D features an explosion proof motor and starter with a spark proof blower design (Class I Zone 2, AEx d nA IIA T3C [US] / Ex d nA IIA T3C [Canada]). Unlike the standard MAC-21, the blower/motor is not removable from the unit cart, and the flex hose inlet is not reconfigurable.
