About Air Compressors

Air compressors are machines that compress and direct air for industrial applications. Small-scale devices are designed for pneumatic tools such as grinders, drills and nail guns. Manufacturing-scale products are used to drive punching and stamping equipment, power robotic tools, and convey parts. Air compressors that are designed for direct-use applications such as sandblasting and spray painting are also available. There are three basic types of air compressors: reciprocating, rotary screw, and centrifugal. Reciprocating air compressors use pistons to compress the contents of an air cylinder and force them into a storage tank. These piston-driven air compressors are designed for intermittent use. Rotary screw air compressors use twin screws instead of pistons to pressurize air. They are designed for continuous use and have a rated duty cycle of 100%. Centrifugal air compressors are turbine engines that use rotating blades to produce high pressures. Typically, these air compressors are used in power generation and large-scale industrial applications.

Products & Services Related to Air Compressors

Air Blow Guns

Air blow guns attach to air lines for the manual actuation and/or control of air discharge. They are used primarily for debris removal and purging, non-contact part cleaning and drying, and general laboratory or industrial applications.

Air Compressor Parts

Air compressor parts are used in air compressors and replaced due to wear and usage. This product area include air compressor motors, filters, pumps, valves, pressure regulators, breathers, and other accessories.

Air Cylinders

Air cylinders are pneumatic linear actuators that are driven by a pressure differential in the cylinder's chambers. They may be single-acting (with a spring return) or double-acting.

Air Hose and Air Duct Hose

Air hose and air duct hose is used in pneumatic systems and controls, or as supply lines for pneumatic devices and tools.

Air Motors

Air motors are powered by compressed air. They operate at relatively high speeds in industrial and spark-prohibited applications.

Air Pressure Regulators

Air pressure regulators control pressure in air lines (usually adjustable) to remove fluctuations and maintain consistent pressure for pneumatic devices.

Air Springs

Air springs use a contained column of air inside an elastomeric bellows or sleeve to buffer cyclic motion, provide vibration isolation, or serve as a pneumatic actuator.

Air Valves

Air valves allow metered fluid flow in one or both directions. They are used in pneumatic circuits to regulate the rate of activation or exhaust of cylinders and other pneumatic devices.

Compressed Air Dryers

Compressed air dryers utilize technologies such as refrigeration, desiccant adsorption, and membrane filtration to remove contaminants, particularly water, from the air.

Compressed Air Filters

Compressed air filters are used to remove water, oil, oil vapor, dirt, and other contaminants from a compressed air supply.
