Rotary Screw Air Compressor Horsepower. When you're shopping for air compressors, you'll typically find that they're rated by horsepower: You'll see the horsepower rating prominently featured in the product name and description, such as the "Quincy 7.5 hp rotary screw air compressor," the "Quincy 30 hp air compressor" or the "Quincy 60 hp air compressor."

Learn what you need to keep your systems running efficiently with our easy-to-use air compressor calculations and formulas tool.

The total power requirement of a compressor for a given duty is the sum of the gas power and the friction power. The gas power is directly proportional to head and mass flow and inversely proportional to efficiency. Mechanical losses in the bearings and, to a lesser extent, in the seals are the primary source of friction power.

Table 1 is part of a compressed air audit intended to show the power savings, even at full load, of a variable-speed, rotary-screw lubricated compressor. The data are based on using current to compare specific power for a pair of 100-hp-class rotary screw compressors. Which option appears to …

Dear All, Rotary Screw compressors are fast replacing piston type reciprocating compressors all over the world. With advancement in technology of precision machining the helical screws required in screw compressors, they are becoming the first choice for selection where otherwise a piston reciprocating compressor would have been used in earlier days.
