The air compressor shall be of the oil injected rotary screw type, designed and installed to supply a minimum of 125 cfm @ 125 psi (2831.7 L/min @ 8.6 b) of free air at maximum engine rpm. The compressor air/oil receiver shall be built and designed by the compressor manufacturer. A spin-on oil filter shall be integrated into the compressor system. Replacement elements shall be readily available.
A pneumatic modulating inlet valve mounted on the air end inlet shall control the compressor. An AutoOdin balancing system shall be provided to automatically maintain the air pressure within plus- Or – minus 5% of the water pump pressure throughout the CAFS operating range.
All air lines shall be rated to a minimum of 250 psi (17.2 b). All control air fittings shall be of brass, stainless steel or chrome construction. Stainless steel or brass check valves shall be utilized at air injection points to prevent water/solution back-flow into air lines.
The cooling water to the heat exchanger shall be supplied through a dedicated, filtered line from the unit’s water pump. Water shall flow through the heat exchanger whenever the water pump is operating. The air compressor cooling system shall incorporate a thermostat that maintains the system oil temperature within 168°F (75.6°C) to 225°F (107.2°C) range. The system shall be capable of maintaining recommended operating temperatures throughout the full operational range of ambient temperatures up to 115°F (46.1°C). A dry cartridge type air filter shall be provided on the compressor air intake.
