Air compressors are devices that take energy from sources such as diesel engines, gasoline engines or electric motors and use it to create potential energy stored in pressurized air. They work by continually pushing air into a storage tank, amplifying the pressure until it can no longer safely raise and at this point the compressor automatically shuts off. This compressed air can then be stored for long periods until it is needed. It is mainly employed to perform tasks such as powering pneumatic tools, filling tires or working a paint-spraying gun.

When it comes to air compressors, there are many models to choose from that each offer a specific purpose. For the DIY enthusiast, portable air compressors are great to power up pneumatic tools. While stationary air compressors are perfect for more industrial uses, such as providing the energy needed for cutting with an air-powered saw in the factory.

Atmospheric air is initially drawn in by the pistons of a reciprocating air compressor and is then compressed in a two-stage process. The first stage compresses the drawn-in air to a relatively low pressure. This lower pressure is then continued to be compressed in a second stage, resulting in a higher pressure until the desired final pressure is achieved.

From lightweight and portable, to powerful and large, reciprocating air compressors make up a broad range of appliance sizes. The lightest models are only one to three horsepower, whereas the heaviest can deliver an impressive 200+ hp. Depending on the horsepower, these amazing machines can provide cubic feet of air per minute–which can be as few as 1 or as many as one might need to power an entire factory!

Powering through the atmosphere, two screw-like components rotate quickly, driven by an engine. As they whirl and intertwine, air is pulled into a tight space between them. Here, it is stored until the screws rotate to the outlet port and compress the air along their journey. This is a rotary screw compressor - a unique type of air compressor.

From hand-held models of 5 horsepower, right up to gigantic powerhouse units of 500 horsepower, rotary screw air compressors come in an array of sizes. Each size brings different capabilities - particularly when it comes to quantity of air provided (measured in cubic feet per minute).

The final variant of an air compressor is the centrifugal one which functions by utilising a rotary impeller to intake air. This impeller exploits centrifugal force to pull air into its blades, casting it outwards to the periphery, creating a low-pressure core that intake air is subsequently sucked into. Finally, as  https://www.sunritaac.com  gets ejected from the impeller, the air is compressed into the outlet port.

From hand-held models to massive industrial sizes, centrifugal air compressors can vary significantly in their output. With a whopping 500 horsepower at the top end and a miniscule 5 hp at the bottom, the capacity of each unit to deliver air (in cfm) is greatly dictated by its size.

When selecting an air compressor, it is important to determine the particular requirements of the intended use. If tools need to be powered pneumatically, then a portable option might be the best option. On the other hand, for industrial applications, a stationary choice might be more suitable.
