2. Rotary-screw compressor - Wikipedia

   en.wikipedia.org/wiki/Rotary-screw_compressor

   A rotary-screw compressor is a type of gas compressor, such as an air compressor, that uses a rotary-type positive-displacement mechanism. These compressors are common in industrial applications and replace more traditional piston compressors where larger volumes of compressed gas are needed, e.g. for large refrigeration cycles such as chillers ...

3. Compressed-air energy storage - Wikipedia

   en.wikipedia.org/wiki/Compressed-air_energy_storage

   The only exhaust gas from each stage is cold air, which can be as cold as −15 °C (5 °F); the cold air may be used for air conditioning in a car. [15] Additional heat can be supplied by burning fuel, as in 1904 for the Whitehead torpedo. [54] This improves the range and speed available for a given tank volume at the cost of the additional fuel.

4. Air compressor - Wikipedia

   en.wikipedia.org/wiki/Air_compressor

   It is an application of a gas compressor and a pneumatic device that converts mechanical power (from an electric motor, diesel or gasoline engine, etc.) into potential energy stored in compressed air, which has many uses. A common application is to compress air into a storage tank, for immediate or later use. When the delivery pressure reaches ...

5. Compressor - Wikipedia

   en.wikipedia.org/wiki/Compressor

   Compressor. A small stationary high pressure breathing air compressor for filling scuba cylinders. Natural gas compressor at a gas well. High pressure reciprocating compressor from Belliss and Morcom, used in the bottling industry. A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.

6. Compressed air - Wikipedia

   en.wikipedia.org/wiki/Compressed_air

   Cooling the air as it leaves the compressor will take most of the moisture out before it gets into the piping. Aftercooler, storage tanks, etc. can help the compressed air cool to 104 °F; two-thirds of the water then turns to liquid. [16] Management of the excessive moisture is a requirement of a compressed air distribution system.

7. Self-contained breathing apparatus - Wikipedia

   en.wikipedia.org/wiki/Self-contained_breathing...

   Demand: 2000 psi to the regulator from the main valve, plus a bypass valve in case of failure, with a two-stage regulator reducing pressure to 50-100 psi. Pressure-Demand : Similar to demand, but with a spring in the diaphragm, which holds the admission valve open, for continuous air flow to the facepiece.

8. Diving air compressor - Wikipedia

   en.wikipedia.org/wiki/Diving_air_compressor

   A diving air compressor is a breathing air compressor that can provide breathing air directly to a surface-supplied diver, or fill diving cylinders with high- pressure air pure enough to be used as a hyperbaric breathing gas. A low pressure diving air compressor usually has a delivery pressure of up to 30 bar, which is regulated to suit the ...

9. Economizer - Wikipedia

   en.wikipedia.org/wiki/Economizer

   The need to use two compressors in a booster set-up tends to increase the cost of a refrigeration system. A two staged system also needs synchronization, pressure control and lubrication. To reduce these costs, specialized equipment has been developed. A subcooled economizer reduces the amount of gas compressors in the system.
