A diaphragm pump ( also known as a Membrane pump, Air Operated Double Diaphragm Pump ( AODD ) or Pneumatic Diaphragm Pump ) is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable non-return check valves ( or flap valves ) to pump a fluid.

* Pneumatic filter, a device which removes contaminants from a compressed air stream

Pneumatic tubes ( or capsule pipelines ; also known as Pneumatic Tube Transport or PTT ) are systems in which cylindrical containers are propelled through a network of tubes by compressed air or by partial vacuum.

Pneumatic tires, which had a larger footprint than iron tires, also were less likely to get bogged down in the mud on unpaved roads.

Pneumatic dilatation causes some scarring which may increase the difficulty of Heller myotomy if the surgery is needed later.

Pneumatic thermostats typically provide output / branch / post-restrictor ( for single-pipe operation ) pressures of 3-15psi which is piped to the end device ( valve / damper actuator / Pneumatic-Electric switch, etc.

A Pneumatic gun differs from a rubber model in that it has a thicker spear that goes inside a sealed internal barrel encased in a hollow sealed outer casing that contains the air which is at ambient pressure until it is pumped up by hand to a pressure usually equal to one strong rubber band.

* Dunlop Pneumatic Tyre Co Ltd v Selfridge & Co Ltd AC 847, 855, Lord Dunedin, " An act or forbearance of one party, or the promise thereof, is the price for which the promise of the other is bought and the promise thus given for value is enforceable.

To improve the efficiency of building operations staff, Johnson Controls introduced the Pneumatic Control Center, which allowed for monitoring and operating all the temperature control devices in a facility from a single point.

In the case of Dunlop Pneumatic Tyre Co Ltd v New Garage & Motor Co Ltd AC 79 the House of Lords upheld the enforceability of the requirement in the resale price maintenance clause, to pay £ 5 damages per item sold below list price, on the basis that it was not a penalty clause ( which would be unenforceable ) but a valid and enforceable liquidated damages clause.

They were controlled by a Pneumatic Camshaft Motor ( PCM ) controller, where an air-operated camshaft controlled the switching of the motors, which was itself governed by an accelerating relay.

It is interesting to note that the building used for filming the Manhattan Museum of Art's exterior was actually the Alexander Hamilton U. S. Custom House near Battery Park, which is within a mile of the original Beach Pneumatic Transit's tunnel location.

Pneumatic motors generally convert the compressed air to mechanical work though either linear or rotary motion.

Pneumatic systems use gasses under pressure to transmit power ; compressed air is commonly used to operate pneumatic tools in factories and repair garages.

Pneumatic or pneumatic wet / dry vacuum cleaners are a specialized form of wet / dry models that hook up to compressed air.

* Pneumatic cylinder, using compressed gas

* Pneumatic motor, a machine that converts the energy of compressed air into mechanical motion

* Pneumatic tube, a method of transportation utilising compressed air

Pneumatic systems are extensively used in industry, where factories are commonly plumbed with compressed air or compressed inert gases.

Pneumatic systems in fixed installations such as factories use compressed air because a sustainable supply can be made by compressing atmospheric air.

Pneumatic devices are still used in processes where compressed air is the only energy source available or upgrade cost, safety, and other considerations outweigh the advantage of modern digital control.

The British employed Pneumatic valve bodies to regulate gear shifting by charging pistons with compressed air within the gearbox.

Pneumatic motors generally convert the compressed air to mechanical work through either linear or rotary motion.

Pneumatic tools can also be driven by compressed carbon dioxide () stored in small cylinders allowing for portability.

Pneumatic actuators, or pneumatic cylinders, are similar to hydraulic actuators except they use compressed gas to provide pressure instead of a liquid.

Pneumatic post or pneumatic mail is a system to deliver letters through pressurized air tubes.

* Pneumatic post stamps — for mail sent using pressurized air tubes, only produced in Italy.

Pneumatic actuators and hydraulic actuators need pressurised air or liquid lines to supply the actuator: an inlet line and an outlet line.

Pneumatic air guns utilize pre-compressed air as the source of energy to propel the projectile.

* Pneumatic air guns

Pneumatic logic systems ( sometimes called air logic control ) are often used to control industrial processes, consisting of primary logic units such as:

* Pneumatic: the governor mechanism sense air flow from the flywheel blower used to cool an air-cooled engine.

* Pack ( aircraft ), P. A. C. K ( Pneumatic Air Cycle Kit ), a kit containing an air cycle machine that provides air conditioning as part of an aircraft's environmental control system

* Pneumatic — the rig is primarily powered by pressurized air

* Pneumatic conveying systems often employ filtration to stop or slow the flow of material that is transported, through the use of a baghouse.

In Ghostbusters II, the " river of slime " under New York city is found by the Ghostbusters boys to be flowing through an old pneumatic tube line – a reference to the Beach Pneumatic Transit tube.

It was advertised as an “ Exclusive Pneumatic Down-stroke Filler .” To fill it, a knob at the end of the barrel is unscrewed and the attached plunger is drawn out to its full length.

Pneumatic dilatation is most effective on the long term in patients over the age of 40 ; the benefits tend to be shorter-lived in younger patients.

Pneumatic logic is a reliable and functional control method for industrial processes.

Pneumatic or elastic tires help by providing some springing for most of the ( otherwise ) unsprung mass, but the damping that can be included in the tires is limited by considerations of fuel economy and overheating.

* March-The Pneumatic Institution for research into the medical implications of newly-discovered gases is established by Thomas Beddoes in Bristol.

Low Church Anglicans believe in Pneumatic presence, or that Christ is mystically present in the faithful participation of the sacrament, but his physical person is in no way attached to the elements, nor do the elements become his physical body and blood.

; Pneumatic retinopexy: This operation is generally performed in the doctor's office under local anesthesia.

Pneumatic or hydraulic tools are particularly likely to be used in mines where there is an explosion risk ( such as underground coal mines ), since they lack any high-power electrical circuitry that might cause a triggering spark.

Occupied from Elizabethan times to the present day, the main buildings were built for the military protection of Milford Haven in the 1850s, but the most unusual feature is its use for trials of Edmund Zalinski's Pneumatic Dynamite Gun in the 1890s.

Pneumatic grinders are generally used for lighter duty jobs where more precision is required.
