Air and gas systems
Compressors & Vacuum Equipment replacement guide
Replace air compressors, vacuum pumps, blowers, dryers, separators, regulators, boosters, and service components using capacity, pressure or vacuum, gas, duty, and interface data.
Evidence boundary. Compressor and vacuum replacements should be evaluated as systems. Horsepower or connection size alone does not establish capacity, duty, controls, or gas compatibility.
