  2. Pneumatic tube - Wikipedia

    en.wikipedia.org/wiki/Pneumatic_tube

    A pneumatic tube system in Washington, D.C., in 1943. Pneumatic tubes (or capsule pipelines, also known as pneumatic tube transport or PTT) are systems that propel cylindrical containers through networks of tubes by compressed air or by partial vacuum. They are used for transporting solid objects, as opposed to conventional pipelines which ...

  3. Medical gas supply - Wikipedia

    en.wikipedia.org/wiki/Medical_gas_supply

    Medical oxygen storage tanks at the Royal Women's Hospital, Melbourne, Australia. Oxygen may be used for patients requiring supplemental oxygen via mask. Usually accomplished by a large storage system of liquid oxygen at the hospital which is evaporated into a concentrated oxygen supply, pressures are usually around 345–380 kPa (50.0–55.1 psi), [1] [2] or in the UK and Europe, 4–5 bar ...

  4. Pneumatics - Wikipedia

    en.wikipedia.org/wiki/Pneumatics

    Pneumatics (from Greek πνεῦμα pneuma 'wind, breath') is the use of gas or pressurized air in mechanical systems. Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically-powered compressor powers cylinders, air motors, pneumatic actuators, and other ...

  5. Laminar flow cabinet - Wikipedia

    en.wikipedia.org/wiki/Laminar_flow_cabinet

    Preparation of microbiological samples in a laminar chamber. A laminar flow cabinet or tissue culture hood is a partially enclosed bench work surface designed to prevent contamination of biological samples, semiconductor wafer, or any particle-sensitive materials.

  6. Tubular-pneumatic action - Wikipedia

    en.wikipedia.org/wiki/Tubular-pneumatic_action

    Two basic types of tubular-pneumatic actions were used: the "pressure" system and the more popular "exhaust" system. Both use three major components for each key and stop: a valve (within the console), a pneumatic motor, commonly called a 'pneumatic' (within the windchest), and a lead tube that connects them.

  7. Chest drainage - Wikipedia

    en.wikipedia.org/wiki/Chest_drainage

    The simplest system that is sufficient for chest drainage is a one-chamber system. It uses either a Heber-drain or an active suction source and comprises a single collection canister. For active or passive air evacuation, a water seal component is attached.

  8. Air-operated valve - Wikipedia

    en.wikipedia.org/wiki/Air-operated_valve

    Modulating control valves each with 4-20mA I to P converter linked to pneumatic a valve positioner controlling a diaphragm actuator. An air-operated valve, also known as a pneumatic valve, is a type of power-operated pipe valve that uses air pressure to perform a function similar to a solenoid.

  9. Pneumatic cylinder - Wikipedia

    en.wikipedia.org/wiki/Pneumatic_cylinder

    Pneumatic systems are often found in settings where even rare and brief system failure is unacceptable. In such situations, locks can sometimes serve as a safety mechanism in case of loss of air supply (or its pressure falling) and, thus remedy or abate any damage arising in such a situation. Leakage of air from the input or output reduces the ...
