General view about air compressors is that they are used for filling tires with air pressure, but it functions much more than that. Experts in construction industry use air compressor to provide effective pressurised air to the power equipments. They can be easily seen to be used in refrigerators, air conditioners and motorcycle, to name few. Use on a large scale has prompted companies producing air compressor in India and around the globe to come up with better advanced products.
Compressors simply convert gaseous energy into kinetic form by compressing and pressurising air. Next the air is allowed to flow with sudden gush. Air is stored into compressor tanks, wherein the process is more manageable. Because of its portability people use it to fill air in their vehicles tires whenever the need may arise.
There are two methods in which air can be compressed. They are through negative displacement or the positive one. The main integrals of the compressor includes air filters. Filters remove dirt and contamination after compression is done with. Pistons used in compressors pump air to a particular spot. The three basic types of compressors are rotary, centrifugal and reciprocating. Further classification is on the basis of various other features such as stages, cooling based and lubrication.
Compressors on the basis of stages can be single or multi staged. In single stage compressor, a cylinder forces air directly in storage tank. On the other hand, multi stage uses multiple cylinders for the same work. Single stage are worthwhile for work on a smaller scale. Industrial applications using heavy machinery require multi stage compressors for high pressure use.
Oil free air compressors are mostly used for small homely jobs. As the name suggests, they do not need oil for operation and screws do the compressing action. Of them, the rotary type is a favourite. Oil free type avoids oil spills and grease which usually is the case with compressors. The only missing point is its inability to handle large pressure which oil types easily can. They are easy to handle and inexpensive on pocket.
Compact and portable form of compressors are for personal use. Lot of factors are to be looked at before buying one. Factors such as horsepower capacity, quality performance, durability, operating and maintaining cost. Durability needs special attention as long life is a must in any industrial use. Cast iron type of cylinder used in compressors improves the durability. Regular oil lubrication enhances sturdiness. Ensure the compressor's strength suits your requirement.
There is a long list of companies manufacturing air compressor in India. A little research and information will help you choose a better product.
