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

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 tube systems are used in science, to transport samples during neutron activation analysis.

Pneumatic post systems were used in several large cities starting in the second half of the 19th century ( including an 1866 London system powerful and large enough to transport humans during trial runs – though not intended for the purpose ), but were largely abandoned during the 20th century.

Pneumatic, hydraulic, water, and electrical systems may also be identified.

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

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

* Pneumatic mail systems

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

** Pneumatic systems tend to have long operating lives and require very little maintenance.

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

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.

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.

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

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.

Pneumatic tube networks gained great prominence in the late 19th and early 20th century for businesses or administrations that needed to transport small but urgent packages ( such as mail or money ) over relatively short distances ( within a building, or, at most, within a city ).

** Pneumatic post, using capsules to move paper and small goods through tubes.

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

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.

Fievel and Tony discover that an ancient treasure lies underneath Manhattan when snooping around an abandoned subway ( the Beach Pneumatic Transit system ) and stumbling upon the remains of a dead mouse clutching a treasure map, deciding they must find it with the help of an archaeologist Tony knows: Dr. Dithering, along with fighting five villains as well.

Until it closed in early 2011, a McDonald's in Edina, Minnesota claimed on its receipts to be the " World's Only Pneumatic Air Drive-Thru ," sending food from their strip-mall location to a drive-through in the middle of a parking lot.

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.

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 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.

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.

Pneumatic and hydraulic cylinders, or lead screw can be designed to provide force in both directions.

Pneumatic forks were not to be a Vincent innovation, with both Phils believing girder forks were superior at the time.

In Portal and Portal 2, two other popular games, Aperture Science uses Pneumatic tubes to transport larger-scale objects such as boxes of all kinds throughout their enrichment center.

Pneumatic tires are used on many types of vehicles, such as cars, bicycles, motorcycles, trucks, earthmovers, and aircraft.

Pneumatic tires are used on many types of vehicles, such as bicycles, motorcycles, cars, trucks, earthmovers, and aircraft.

Harbor Freight Tools sells products under its store brands such as Chicago Electric, Drill Master, Central Machinery, Central Pneumatic, Central Hydraulics, U. S. General, Western Safety, One-Stop Gardens, Haul-Master and Pittsburgh Tools.

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

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

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

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

* Pneumatic tube, a method of transportation utilising compressed air

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

* Pneumatic air guns

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

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.

* 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

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

* Pneumatic — the rig is primarily powered by pressurized air
