Portable Filtration Units
SP-125VS Filtration Unit
The SP-125VS variable speed HEPA filtration unit is a small, easily transportable tool for contamination control. Suitable for use in confined spaces, it is perfect for spot ventilation, welding, torus work, glove bag and gloved enclosure air cleaning. The optional carbon prefilter is useful for fume or vapor control where those elements are necessary. The stainless steel cylindrical design facilitates cleaning and increases the durability of the unit.

MAC-21 Series
MAC-21 Ventilation Unit
The MAC-21 is a modular ventilation unit capable of providing High Efficiency Particulate Air (HEPA) filtration with 99.97% efficiency @ 0.3 microns.
The MAC-21 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 Cart- 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 (Fans and Blowers) and Canada under product Class 3812-01 (Fans and Blowers).

MAC-21 Series
MAC-21D Ventilation Unit
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.
This unit has been evaluated to the applicable CSA standards for use in the United States under product Class 3812-81 (Fans and Blowers) and Canada under product Class 3812-01 (Fans and Blowers).
