The BAC series provides versatile ambient air pumps in electric, pneumatic, and explosion-proof configurations to support up to four workers using constant flow respirators. To ensure OSHA 1910.134 compliance, these compressors must operate in clean air environments and require the simultaneous use of both intake and discharge filters. For added safety and comfort, models feature optional CO monitors and Twin-Air tanks that significantly lower output air temperatures. These rugged systems are the ideal industrial solution for low-pressure applications like abrasive blasting, painting, and confined space work.
