Inlet Filter Assembly for "SVB"
Series Blowers

This inlet filter is designed to fit Air Systems' "SVB" series of portable industrial blowers. The unit filters the ambient air where the blower is located so that workers in a confined space are not exposed to ambient dusts. This system will control dusts and particulates from entering a confined space where industrial coatings are being applied. The filter will also reduce the potential for dust ignition in confined space when used with an explosion-proof or intrinsically safe blower. Filters are available with 5 micron of 99.97% HEPA rating.

The Industrial Saddle Vent®

Designed to Ventilate Non-Hazardous Locations

The Saddle Vent® was developed by Air Systems and has been in use around the world for over 30 years to make it easier and safer for workers to enter and exit a confined space. The Saddle Vent® takes up only 3 inches in a manhole opening and functions as a fresh air conduit to the workers in the confined space. With the Saddle Vent® in place, continuous ventilation is supplied to the workers by eliminating the need to remove the air duct each time a worker needs to enter or exit a confined space, increasing safety and productivity.
