Abstract
This invention increases the flow of breathable air from an air pump to an enclosure such as a hood or enclosed structure without requiring an increase in the air pump output. The invention involves interposing an jet venturi induction pump in the conduit between the air pump and the enclosure. Breathable filtered, muffled, and metered ambient air is induced into the jet venturi induction pump, thereby increasing the flow of breathable air into the enclosure without an increase in the air pump output. In addition, the jet venturi induction pump cools and reduces the humidity of the air emitted from the air pump.
