Air Compressors - how to choose one

There are three main types of air compressors. You need will depend on air pressure you need and how to be your portable compressor.
Piston compressors come in a variety of 5 hp to 1000 hp. Air compressors, is mounted in some cases, small portable computers on wheels. It may be an electric motor or gasoline. Are the air pressure with a series of pistons in the cylinders. Pistons are driven by the camshaft. Are often used in piston compressors Car body repair shops.

Are gradually replacing reciprocating compressors and wide by a simple rotary screw compressors. And can be vented and large reciprocating compressor to 35 MPa, more than 5000 lbs.

May if you are looking for a compressor for continuous use for the rotary screw compressor is appropriate. Used helical screw compressors to compress the gas to a smaller size. Portable and stationary rotary screw compressors available. These compressors vary in size from 5 hp to 500 hp. You can find rotary screw compressors that give you the low pressure gas outlet, or high pressure, up to 8 MPa. These compressors are used for the electrical breaker when workers digging roads and sidewalks.

Continuous use of heavy and industrial need to centrifugal compressor. The centrifugal compressor blade using rotating disk. And can output centrifugal compressors can be up to 70 MPa 0.10000 lbs. Woodwind snow use this type of compressor. Compressors and turbo-engined cars and centrifugal compressors.

And pressed when you buy compressed air for air diving using the third step, a piston compressor. Compressor cylinders, ceramics, lined up, so there is no need for lubrication. This prevents contamination of the air in the cylinders with oil lubrication. If you use oil lubrication is recommended, it may undergo partial combustion and cause carbon monoxide to enter the air cylinder.

The compressed air is filtered through silica gel to remove water, followed by activated carbon to remove all traces of oil.

And sometimes it is stored in the air of a cheap, low-power compressor in a large bank of high pressure cylinders. Is then used air from the cylinder to fill the tanks to breathe under water quickly. Must be filled bottles diving slowly to avoid the heat of the compressed air inside. If the gas is hot inside, and will expand and maximize pressure on the cylinder with less air inside. Gas cools and the cylinder can only be full and a half.
