Different Types Of Commercial Compressors

A commercial compressor is a device that generates and compresses great amounts of air within a particular space. Since there are many different applications that depend on using compressed air, there are many types of commercial compressors. Each type of commercial compressor has specific features and characteristics. Tank size, tank style, portability, powering methods and air capacity, these ares some of the biggest differences of compressors used for commercial applications. If you visit a market today, you will find a variety of commercial compressors that will easily confuse you. To prevent such thing, all you need to do is learn the three most popular types of compressors used for commercial purposes. Let's start.

Screw Compressors – Screw compressors, or rotary screw compressors, are gas-powered compressors that use rotary-type positive displacement mechanism to force air into a sealed chamber. These commercial compressors come in two different varietals: dry screw compressor and oil-flooded compressor. The screw compressor does not use any lubricated seal to function properly, that's where it's name comes from. The chamber of oil-flooded compressors is completely filled with lubricating oil, which divides the force between the two screws (rotors). These commercial compressors are most commonly used in commercial, construction and industrial fields.

Portable Compressors – The portable type of commercial compressor is a basic compressor with the advantage of being portable. Portable compressors are usually used to power various pneumatic tools and inflate tires of vehicles. While being efficient for many different applications, portable compressors are certainly most efficient for commercial purposes. After completion of a particular process, these can be conveniently moved to the next job site or stored safely. Bigger models of portable commercial compressors can be even towed by a vehicle or truck.

Reciprocating Compressors – Reciprocating compressors compress gasses using positive displacementmechanism. These compressors are composed of a crankshaft driven piston, positioned in a closed cylinder along with outlet valves. The reciprocating compressor draws gas into the cylinder, compress it and send it into the holding tank. The process is repeated as long as a constant supply of compressed gas is not achieved. Reciprocating compressors can be used for compressing many different gasses, such as air, oxygen, refrigerants, hydrogen and hydrocarbons. However, these commercial compressors are limited to applications that do not involve a lot of moisture.
