ABSTRACT:
A system and method for providing filtered and pressurized air into a vehicle cab, enclosure or other interior enclosed environment is described, in which a filtered positive pressure air unit comprises a sealed box, a HEPA filter, a blower, a magnahelic, power source and ductwork. Dirty air is drawn by the blower through the hose and ductwork to the HEPA filter where a certain percentage of impurities of a certain size or larger are removed. Clean air is discharged at a sufficiently high rate to create a positive pressure inside the interior enclosed environment, keeping clean air in, and dirty air out.
