For example, if both a 5 and 10 HP compressor can consistently output 100 PSIG at a rate of 15 CFM, the 5 HP unit is a more powerful and energy-saving model. When everything is in balance, HP provides a measurement of an air compressor’s output performance for a specified level of PSIG and CFM. If you’d like to run more than one air-powered tool simultaneously, you’ll need a higher CFM rating. CFM: Cubic feet per minute reveal the ceiling of how much an air compressor can output at a specific pressure level.Most air-based tools need a score of at least 90 PSIG. PSIG: Pounds per square inch gauge is an air pressure measurement critical for air-powered tools.

Horsepower, pressure (PSIG) and capacity (CFM) are the primary three methods to measure a compressor’s overall performance power.Įach of these terms has a distinct definition: This complex process means that the ratio of horsepower to the compressor’s overall production power isn’t always obvious. The motor’s job is to propel the cylinders or the rotary screw that compresses the air. In general, horsepower refers to 550 foot-pounds of power per second, or 745.7 watts.Įvery compressor has a motor that receives a horsepower rating. Horsepower provides a measurement of how much performance your engine can output. The experts at Quincy Compressor have created this guide to walk you through the meaning of HP and what factors to consider before your next air compressor purchase. Yet, HP ratings are only one small part of the overall criteria for making the best choice. When purchasing a new compressor, many people look to the horsepower (HP) rating as a deciding factor. An air compressor is an important tool across many industries, and selecting the right model for your project is vital to your success.
