Types of Compressor Units Available

’Light Duty’ Oilless Type

Reciprocating Type

Rotary Screw Type

There is a wide variety of Air Compressor Units available, Units used for anything from pumping up bicycle tires

periodically to operating large and expensive industrial machinery 24 hours per day. As there is such a variation of

uses and demands for compressed air, there are also Compressor Units suitable for each particular use.

Compressor Units are available in various configurations, each configuration being fairly unique based on

Compressor volume, pressure, and HorsePower. To follow is a brief description of some of the more common Unit

configurations.

Though this is by no means a complete listing of all types of Compressors, it does note the major Units available. For

intermittent applications below 30 HP, the most commonly used Unit is the Reciprocating Compressor Unit due to its

moderate pricing, relative simplicity, and substantial performance characteristics.

What are the more common types of Units used ?

- 6 -

* generally small, portable hand held, electrically driven Units

* used for 'household' applications, hobbyists

* oil free operation, so no oil downstream

* not moisture free

* generally run constantly while connected to power

* air delivery is limited from about 1 to 3 CFM

* air pressures are in the 30 to 40 psi range

* inexpensively priced, widely available, very little maintenance required

* though available in portable Units, the majority of the larger Units are stationary

* used for 'household' (portables), automotive, and industrial applications

* generally use an oil lubricated Compressor Pump, so oil downstream is a consideration

* generally run intermittently (ie. not 'on' continuously)

* air delivery generally limited to approximately 125 CFM(typically a 30 HP Unit)

* air pressure is 150 to 175 psi maximum

* moderately priced, automotive/industrial Units available through select distribution, regular

maintenance required

* generally available as stationary Units, though some portable Units are also available

* generally used in industrial applications, and those where great volumes of air are required, on an almost

continuous basis

* generally oil lubricated Compressor Pump (Air End)

* air delivery available to several thousands of CFM

* typical Units have a maximum air pressure of 120 psi, though they can go as high as 200 psi

* relatively expensive to purchase, available through select distribution, regular maintenance is critical (by

competent service company, and though somewhat more expensive than reciprocating Units,

maintenance is less frequent)
