Specifications include, but are not limited to: The air compressor system shall be a turnkey, packaged appliance designed to deliver high pressure breathing air in compliance with the most current NFPA and CGA air quality standards for the refilling of SCBA and SCUBA cylinders. The system shall include the high pressure air compressor, electric motor, air purifier, fill station and all operating and cylinder fill controls as specified below. The system must also be designed to incorporate an integral air storage system as specified below. All components shall be completely assembled and tested by the manufacturer as a system and incorporated within a single appliance requiring only electrical power supply to operate. The system shall be designed with all cylinder refilling, operator controls and performance indicators located on panels at the front of the appliance allowing "at sight" operator monitoring. The appliance shall comply with the currently applicable OSHA specifications as well as state and local electrical codes. The external construction of the high pressure breathing air compressor system shall be appliance-like. All structural fasteners shall be concealed and all access panels shall include concealed hinges and push button latches. One full height door shall be provided for maintenance access to the compressor. The door shall include a shutdown switch to prevent exposure to running gear in the event it is opened while the compressor is in operation.
