155 CFM

Any 155 CFM air compressor figure only qualifies once you know the working PSI it was rated at, since delivered air falls as the required pressure rises. Use this category as an airflow-based filter, and make your central check comparing rated delivery at your actual working pressure against the total air your tools or processes demand.

Matching 155 CFM To Intermittent And Sustained Demand

Your application shapes what 155 CFM can cover. Intermittent work pulls air in bursts, while sustained tools, production processes, and simultaneous users keep demand steady and leave less room to spare. At this airflow level the compressor will typically be a rotary screw, which runs at 100% duty and can be sized closer to the required demand. That still leaves the working PSI as the qualifier, since the same unit delivers less air as required pressure climbs.

Checking Air Demand At 155 CFM

Add up the air every tool or process uses when operating at the same time, then measure that combined figure against a compressor's rated 155 CFM delivery at your working PSI. Leave a reasonable operating buffer above your total so recovery keeps up with steady use. If your verified demand lands below this level, the 150 CFM air compressors category may fit a lighter load, while demand that runs steady is worth weighing against the 185 CFM air compressors for added margin.

FAQ:

How much airflow headroom should I allow above my calculated figure?
Allow a reasonable operating buffer above your totaled demand so recovery keeps pace with steady use, and size that margin to how continuously your tools or process draw air.
