2. Compressed air foam system - Wikipedia

   en.wikipedia.org/wiki/Compressed_air_foam_system

   By the 1960s do-it-yourself car washes were using CAFS with low pressure and small-diameter hoses and nozzles, which flowed about 4 US gallons (15 L) per minute of solution and 4 cubic feet (0.11 m 3) per minute of compressed air, with a nozzle reach of about 40 feet (12 m) (Rochna and Schlobohm, 1992).

3. Gas duster - Wikipedia

   en.wikipedia.org/wiki/Gas_duster

   A gas duster, also known as tinned wind, compressed air, or canned air, is a product used for cleaning or dusting electronic equipment and other sensitive devices that cannot be cleaned using water. This type of product is most often packaged as a can that, when a trigger is pressed, blasts a stream of compressed gas through a nozzle at the top.

4. Shotcrete - Wikipedia

   en.wikipedia.org/wiki/Shotcrete

   Wet-mix shotcrete involves pumping of a previously prepared concrete, typically ready-mixed concrete, to the nozzle. Compressed air is introduced at the nozzle to impel the mixture onto the receiving surface. The wet-process procedure generally produces less rebound, waste (when material falls to the floor), and dust compared to the dry-mix ...

   Applied using eductor or compressed air foam system (CAFS) and pumped through fire hose to a foam nozzle (or sometimes a less-effective fog nozzle). Attack hose (Attack line) A use classification of a fire fighting hose connected to output of a pump or other pressure source (e.g., gravity). Fire hose used to apply water or other fire fighting ...

6. Vortex tube - Wikipedia

   en.wikipedia.org/wiki/Vortex_tube

   With no moving parts, no electricity, and no refrigerant, a vortex tube can produce refrigeration up to 1,800 W (6,000 BTU/h) using 100 standard cubic feet per minute (2.832 m 3 /min) of filtered compressed air at 100 psi (6.9 bar). A control valve in the hot air exhaust adjusts temperatures, flows and refrigeration over a wide range.

7. Self-contained breathing apparatus - Wikipedia

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

   An open-circuit SCBA does not recirculate air; it instead allows respired air to be exhausted outside. While 30 CFR 11 does not restrict the gas that can be used (although compressed air is usually chosen), use of compressed oxygen is not allowed due to the system's exposure to outside air. Duration is usually limited to 30-60 minutes. [13]
