Portable air compressor system for respirator
First Claim
1. In an air compressor system for use with a respirator adapted to be operated from a source of power, a plurality of compressors, each of said compressors having a fan for causing air to move over the compressors and having an inlet for receiving atmospheric air and outlet for supplying a compressed air, a cooling coil having an inlet and a outlet positioned so that the fans of said compressors force air over the cooling coil, means connecting the outlets of the compressors to the inlet of the cooling coil, a water trap, means connecting the outlet of the cooling coil to the water trap, a reservoir having inlet connected to the water trap a pressure regulator in communication with the reservoir and a pressure switch connected to the reservoir and to at least one of the compressors for halting operation of said at least one compressor when a predetermined pressure is reached in the reservoir.

Abstract
Portable air compressor system for a respirator and adapted to be operated from a source of power. A plurality of compressors are provided. Each compressor has a fan for causing air to move over the compressor and has an outlet supplying compressed air. A cooling coil is provided having an inlet and an outlet and is positioned so that the fans of the compressors force air over the cooling coil. Piping connects the outlets of the compressors to the inlet of the cooling coil. A water trap is provided. Piping connects the outlet of the cooling coil to the water trap. An air reservoir is provided which has an inlet that connects it to the water trap and an outlet which is adapted to be connected to the respirator. A pressure regulator is provided which is in communication with the reservoir. A pressure switch is provided which is connected to the regulator and at least one of the compressors for halting operation of said at least one compressor when a predetermined pressure is reached in the reservoir.
