The high pressure air purification system shall be a multi-chamber arrangement that utilizes a disposable cartridge manufactured to provide breathing air quality that meets or exceeds NFPA and CGA Grade “E” specifications and all other equivalent and recognized standards in use worldwide. All system components shall be rated for 6000 PSI working pressure. All chambers in the system shall be constructed of 304 stainless steel to enhance safety and corrosion resistance. All purification system components shall be mounted on a formed steel panel suitable for wall mounting and that permits complete access to all service components from the front. The panel construction shall be appliance-like without visible welds; burrs or grinding marks and finished with scratch resistant powder coat paint.

II. Compressor

The purification system shall be sized to process 85,000 cubic feet of air at 80° F. and compressed to 6000 PSI between cartridge changes.

The system shall include the following:

• Final separator chamber.
• Check valve to prevent backpressure to the compressor.
• One (1) 33" desiccant cartridge chamber.
• One (1) 33" purifier cartridge chamber.
• Pressure maintaining valve to assure that the system is maintained pressurized in order to attain the rated processing capacity of the air purification cartridge.
• Safety relief valve.
• Drain valve to relieve the system pressure for maintenance.
• Stem-mounted gauge for system pressure verification.

The system shall be designed so that air cannot flow through the purifier in the event that the disposable cartridges are not installed. Additionally, the purification system shall have "keyed" chambers so that the filter cartridges can only be installed in their proper sequence.
