Inflator with cooling fan

Abstract

An inflator is disclosed having a housing and a motor assembly within the housing. A first output line is in fluid communication with a first end of the motor assembly to provide a cooling path of air and a high-volume flow of air. The first output line provides a guiding path for the egress of the high-volume flow of air from the housing. A second output line is in fluid communication with a second end of the motor assembly and to provide a high-pressure flow of air.
