Reciprocating Compressors or Piston Compressors are generally used to move gas at increased pressure. They are regarded as the most energy-efficient type of compressor for most applications other than those involving small amounts of gas.

Oil-Less or Oil-free compressor technology was design to minimize increasing difficulties to keep air clean. Today, oil-free compressors are becoming the norm, mostly because they offer very significant cost savings while securing a continuous higher air purity rate. These purity and environmental benefits will often translate into other savings that may reduce your overall ownership costs.

An oil-lubricated screw compressor could run continuously for the entire length of a working day and suffer no ill effects. This is particularly important for manufacturing, where a stopped compressor will impact production. It is also applicable where the air demand is difficult to predict or where attempting to control this demand is undesirable.

A rotary vane compressor forces air or gas (flammable gas or combustive gas) through spinning blades to create compressed gas to the desired pressure defined by the manufacturer. The advantages of rotary vane compressors are the low cost and more compact dimensions, making these the best choice for lower capacity applications such as for example fridge-freezers, air conditioners.
