Air Compressor Solutions

The airend on a compressor package is the component that takes in the air, compresses it and discharges it to the rest of the package. Using 37kW as an example, you can utilize a small airend (small rotor diameter), turn it at a relatively fast speed (revolutions per minute) and use about 37 kW worth of power.

Alternatively, you can make the airend larger which allows it to rotate at a slower rate while still utilizing about 37 kW worth of power. Thus, the airend size (and cost) for different 37 kW compressors will vary significantly.

It is fairly common for a manufacturer to offer a compressor with a smaller, faster rotating airend and a model with a larger, slower turning airend at the same kW because the larger airend is generally more energy efficient than the smaller airend.

Since the electrical cost of operation is the largest expense associated with operating a compressor, the larger airend will save reduce running costs over time, in many applications where power consumption is a key factor. In providing this size/speed offering in the same flow range, the customer can select the model that best meets the budgetary and operating cost targets that have been set.
