2. 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 ...

3. Self-contained breathing apparatus - Wikipedia

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

   An open circuit SCBA typically has three main components: a high-pressure gas storage cylinder, (e.g., 2,216 to 5,500 psi (15,280 to 37,920 kPa), about 150 to 374 atmospheres), a pressure regulator, and a respiratory interface, which may be a mouthpiece, half mask or full-face mask, assembled and mounted on a framed carrying harness.

4. Air compressor - Wikipedia

   en.wikipedia.org/wiki/Air_compressor

   Air compressor supplies air into a nail gun.. An air compressor is a machine that takes ambient air from the surroundings and discharges it at a higher pressure. 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.

5. Compressed air foam system - Wikipedia

   en.wikipedia.org/wiki/Compressed_air_foam_system

   Description. A compressed air foam system is defined as a standard water pumping system that has an entry point where compressed air can be added to a foam solution to generate foam. The air compressor also provides energy, which, gallon for gallon, propels compressed air foam rather than aspirated or standard water nozzles.

6. Compressed air - Wikipedia

   en.wikipedia.org/wiki/Compressed_air

   Compressed air is air kept under a pressure that is greater than atmospheric pressure. Compressed air in vehicle tyres and shock absorbers is commonly used for improved traction and reduced vibration. Compressed air is an important medium for transfer of energy in industrial processes, and is used for power tools such as air hammers, drills ...

7. Cascade filling system - Wikipedia

   en.wikipedia.org/wiki/Cascade_filling_system

   Cascade filling system. A cascade filling system is a high-pressure gas cylinder storage system that is used for the refilling of smaller compressed gas cylinders. [1][2] In some applications, each of the large cylinders is filled by a compressor, otherwise they may be filled remotely and replaced when the pressure is too low for effective ...
