ABSTRACT:
Apparatus is provided for controlling the pressure of gas in a plurality of dunnage bags. The apparatus employs an enclosure which houses a pressure regulator valve, linear air reset controller, pressure gauge, pneumatically activated electrical switch, and three-position valve for permitting quick filling of the dunnage bags from a high pressure inlet line. A low pressure line emerges from the enclosure and communicates with the bags. When the bags are at proper inflation, the electrical switch causes a green light to be illuminated. When the bags are inadequately inflated, the electrical switch causes a red light to be illuminated.
