The Auto-Air™ Cart

The Auto-Air™ Cart provides a systems approach to breathing air filtration.  One cart contains our Grade-D filtration unit, and either a pneumatic or electric reserve air system and twin air cylinder storage.  Choose a cart size based on the desired amount of reserve air needed to allow workers to safely egress the work area.  Carts can operate with either 2400 or 5000psi cylinders. The pneumatic version should be selected for hazardous environments.
