As an example, a 250 HP compound compressor is a large piece of equipment that generally requires a special foundation, building accommodations and highly trained riggers to place the equipment. On the other hand, a 250 HP rotary-screw compressor can be placed on an ordinary shop floor using a standard forklift .
1909 500 kW Westinghouse rotary converter. A rotary converter is a type of electrical machine which acts as a mechanical rectifier, inverter or frequency converter.. Rotary converters were used to convert alternating current (AC) to direct current (DC), or DC to AC power, before the advent of chemical or solid state power rectification and inverting.
A rotary vane compressor is well suited to electric motor drive and is significantly quieter in operation than the equivalent piston compressor. Rotary vane compressors can have mechanical efficiencies of about 90%. [12]
For example, 10–12% of all power generated in the UK is dedicated to the production of compressed air and a portion of this power is wasted energy. Large electrical cost savings can be achieved by installing a variable speed drive compressor in place of an existing rotary screw or piston machine.
The General Electric J79 was the first major example of a variable stator design, and today it is a common feature of most military engines. Closing the variable stators progressively, as compressor speed falls, reduces the slope of the surge (or stall) line on the operating characteristic (or map), improving the surge margin of the installed unit.
The relatively recently developed conical screw compressor is a type of rotary-screw compressor using a different topology from the typical dual-screw type. In effect it can be thought of as a conical spiral extension of a gerotor , although the exact geometry is somewhat different due to the angular offset.

The simplest inlet to a centrifugal compressor is typically a simple pipe. Depending upon its use/application inlets can be very complex. They may include other components such as an inlet throttle valve, a shrouded port, an annular duct (see Figure 1.1), a bifurcated duct, stationary guide vanes/airfoils used to straight or swirl flow (see Figure 1.1), movable guide vanes (used to vary pre ...
