Rotary Screw Air Compressors
Rotary Screw Air Compressors are very complex machinery, and the new wave of technical specs to industry means a much cleaner operational system overall. Use of oils will become obsolete with this new and exciting technology in the near future.
Below are a few differing types and a link to view more information and tech specs.
There are a number of ways in which a compressor can utilise electrical power and convert it into compressed air. The compressor technology that you require will depend largely on your application.
Piston Air Compressor
Piston compressors also known as reciprocating compressors work by converting electrical power into kinetic energy turning a crankshaft either via belt or direct drive arrangement which in turn forces pistons up and down a cylinder. Valves at the top allow air in on the downward stroke and partially close when the piston returns causing a compression of air.
Rotary Screw Air Compressor
Screw air compressors have become the industry standard for professional applications. The technology produces air by turning two screw shaped elements in opposite directions forcing air into a perpetually tighter space. This rotary process is smoother running than a piston compressor providing a more reliable, quieter and improved production of compressed air.
Industrial Air Compressor
Industrial compressors take advantage of energy saving innovations such as variable speed drive technology. A inverter is used to vary the amount of power being sent to the motor depending on the exact current compressed air demand. These compressors ramp up and down to meet fluctuations in compressed air usage.
Other Compressors The other common types of compressors found in the UK are vane and scroll air compressors. A vane uses a rotor filled with blades which turns inside a housing. The blades shift in and out to keep contact with the housing and compress the air. Scroll compressors are popular in the print and dental industry where their low volume oil-free process creates a cleaner final air quality. A scroll machine compresses air using two intertwined spiral elements.
