Air
compressors come in two basic configurations; positive displacement, such as
reciprocating or rotary screw and dynamic, such as centrifugals or
regenerative. Of these two basic configurations, there exists many variations in
their design. From the tremendous amount of design variations you will find
that all have advantages and disadvantages for any particular given application.
Our personnel take the time to determine the most advantageous design for your
particular application prior to giving any recommendation. This determination is
arrived at by careful consideration being given to cost of operation, the
overall operational life of
equipment, the CFM of compressed air required, the maximum discharge pressure required,
the ability of your
facilities maintenance personnel as well as your available budget. We would be
more than pleased to assist you in determining your needs.

Rotary screw
air compressors are the more common compressor used in industries today.
Inherently by design they are approximately 25% more efficient than a
reciprocating "piston" type of air compressor. Sizes of the rotary
screw now very from five horse to several hundred. Discharge pressures
can now range upwards of 350 PSIG. At approximately 10
horsepower, a rotary screw type of air compressor will cost about the same as a
good quality reciprocating unit.
Reciprocating
or piston type of air compressors, although less efficient than a rotary
screw most assuredly still have a position in the marketplace. The
most common use today is small applications, as well as low flow and
high-pressure applications. Due to the ease of multiple staging of
the reciprocating air compressor, these units can easily be designed to
drive compressed air discharge pressures to as high as 9000 PSIG.
Pressure lube and the standard splash lube are both available.
