Air Compressors

Air Compressors and Their multi Types

To some extent similar to pumps, compressors increase the pressure on fluid by reducing the volume of fluid and then transport the fluid through a pipe. Air compressor is used in air tools as a driving tool but before purchasing an air tool the consumer must have the knowledge that the compressor he is purchasing will drive the air tools, some small air tools run on 2-5 CMF whereas the larger air tools like shears, polishers need CMF above than 10. At industrial level, air compressors require more CMF to run for a longer period of time.

CMF requirements of an air tool are ubiquitous to determine for the efficient working of an air compressor. 15 seconds out of a minute is the average CMF of an air tool yet CMF vary from tool to tool. Where electrical power is not available gas powered air compressors are ideal, but electrical powered air compressors are also available and more convenient to use as you can plug them into anywhere. Air compressors are single staged and two staged that are more reliable and durable as they extend the life of compressor by generating less heat, and are used in commercial, industrial and automotive applications. The term single stage implies the air compressors that have one piston to compress the air whereas by two stage means the air compressors those have two pistons; one for compressing the air and the other for distributing it.

Air compressors are used in everyday household use, commercial, industrial and garage use. Air compressors with small tanks are better for house applications while larger tanks are required for the larger applications of industry where air compressors tank is used to store compressed air.

Before buying a compressor, some distinct features should be considered. The buyer must look for an ASME tank; belt driven air compressors should be preferred for they have a longer life with the less transformation of heat, cast iron is the standard material for cylinders of compressors, oil free compressors require less maintenance because there is no need of oil changes occasionally, vertical compressors are stationary and take less floor space whereas horizontal air compressors are typically better for portable applications. Compressor stops and turns on when air is needed, dual control compressors offers auto start/stop and continuous speed operation to adjust the air output.

Ranging from tank less models to heavy duty industrial compressors air compressors are available in wide variety of styles, hence it becomes difficult to select the right one product that meets all your needs. You can shop by brand, style, size and CMF; leading manufacturers of air compressors include AirTech, Contractor, and Maxus etc. innovative work is being done on the technology of air compressors to make them effective and low cost, maximizing compressor performance throughout the load cycle.

Some companies have marketed the compressors with enhanced features, on startup, the inlet control of a compressor remains closed resulting unloaded starting, while on shut down, oil sump is blown down in order to reduce starting torque, modulation inlets are provided for applications where performance and efficiency are improved. Maintenance of air compressors is a necessary prerequisite, so if required periodically oil changes of air compressors must go through.
