[H727]How Air Compressors Work

by Philip Turner, Phi

Reciprocating compressors come in a range from 5 HP to 1000 HP. The smaller compressors are portable, sometimes being mounted on wheels. These may be petrol driven or electrically powered. They compress air by a series of pistons in cylinders. The pistons are driven by a camshaft. Reciprocating compressors are often used in Auto Body Repair shops.

Larger reciprocating compressors are gradually being replaced by simpler rotary screw compressors. A large reciprocating compressor can discharge air at 35 Mpa, more than 5,000 psi.

If you are looking for a compressor for continuous use a rotary screw compressor may be suitable. These compressors use helical screws to compress the gas into a smaller volume. Portable and fixed rotary screw compressors are available. These compressors vary in size from 5 HP to 500 HP. You will find rotary screw compressors that give you a low pressure gas output, or a high pressure output, up to 8 Mpa. These compressors are used to power pneumatic drills when workers are digging up roads and pavements.

For continuous, heavy industrial uses you need a centrifugal compressor. A centrifugal compressor uses a rotating disk with vanes. Output from centrifugal compressors can be as high as 70 Mpa, 10,000 psi. Snow blowing machines use this type of compressor. Superchargers and turbochargers in car engines are centrifugal compressors.

When you buy compressed air for diving the air has been compressed using a three stage, reciprocating compressor. The cylinders in the compressor are ceramic lined, so no lubrication is needed. This avoids the air in the cylinders being contaminated with lubricating oil. If a non-recommended lubricating oil is used it can undergo partial combustion and cause carbon monoxide to enter the air cylinder.

The compressed air is filtered through silica gel to remove water, then through activated charcoal to remove any traces of oil.

Sometimes air from a cheap, low powered compressor will be stored in a bank of large high pressure cylinders. Air from these cylinders is then used to quickly fill diving cylinders. The diving cylinders need to be filled slowly to prevent the compressed air inside them from getting hot. If the gas inside is hot, it will expand and the cylinder maximum pressure will be reached with less air inside. The gas cools and the cylinder may only be half full.

12-volt air compressors are one of the most commonly used devices for lightweight jobs. Industries generally use engine-driven air compressors that run off of natural gas. They use these particular devices to save on the high-energy costs associated with running an air compressor. For those of us who only use an air compressor occasionally, a 12-volt air compressor is probably the best.

All terrain vehicle enthusiasts often use 12-volt air compressors for their off-road needs. You can often find adapters that enable the air compressor to be powered or charged from a vehicle's cigarette lighter. This is a handy and accessible device for people who may not otherwise be located near an electrical power source in which to feed energy to their air compressor.

12-volt air compressors typically work in the same way as other models. Most of them, especially those that are certified by the American Society of Mechanical Engineers (ASME), have advanced safety features. One difference in 12-volt air compressors and other types of air compressors is the power of the air emitted. Most regular users do not need the industrial strength powered air compressors for their everyday use.

Other than ATV enthusiasts, many other uses of 12-volt air compressors exist. People use them, along with attachments, for a variety of uses around the home. They can be used to power nail guns, staple guns, wrenches, spray guns and just about any other kind of tool you can think of. Some homeowners may wish to purchase a 12-volt air compressor if they often have do-it-yourself jobs while others prefer to rent a device. You can usually find devices for rent at most home improvement or hardware stores. It is important that you buy or rent an air compressor that has been certified by the ASME. Otherwise, you may receive a product with substandard workmanship that has not been tested for quality and safety.
