The SA7.5 breathing air compressor (BAC) block is 4 stage, air cooled, splash lubricated, has inter coolers and after cooler, relief valves on all stages, and a multi-blade flywheel fan to provide high velocity cooling over the compressor. Standard BAC equipment includes an auto-drain system, inner stage gauges, hour meter, high pressure shut down, carbon-monoxide visual indicator and a fully enclosed, sound dampened cabinet with gauge panel. The filtration system consists of one chamber rated at 24,000 cu. ft. of air capacity at 80 degrees. The system uses a dryer bed to remove water in excess of dew point ā€“65 degrees. (NFPA 1500 standard) Activated charcoal and a carbon monoxide catalyst remove remaining contaminants to provide CGA Grade ā€œEā€ breathing air. Additional filtration capacity can added for high volume users. The minimum requirement for single-phase operation is a 40 Amp, 230 Volt connection. The minimum requirement for three-phase operation is a 30 Amp, 230 or 208 Volt connection.
