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 ...
An automated vacuum waste collection system, also known as pneumatic refuse collection, or automated vacuum collection (AVAC), transports waste at high speeds through underground pneumatic tubes to a collection station where the waste is compacted and sealed in containers. Full containers are transported away to be emptied.
A vactrain (or vacuum tube train) is a proposed design for very-high-speed rail transportation. It is a maglev (magnetic levitation) line using partly evacuated tubes or tunnels. Reduced air resistance could permit vactrains to travel at very high ( hypersonic ) speeds with relatively little power—up to 6,400–8,000 km/h (4,000–5,000 mph).
Beach Pneumatic Transit was operated from 1870 to 1873 as a one-block-long prototype of an underground tube transport public transit system in New York City, following a concept by Alfred Ely Beach. The system worked at near-atmospheric pressure, with the passenger car moved by means of higher pressure air applied to the back of the car while ...
The system-wide test integrated Hyperloop components including vacuum, propulsion, levitation, sled, control systems, tube, and structures. [8] [45] The company designed and built its first generation full-scale test pod name XP-1 (short for experimental pod one) to be used in the full-scale pod tests. [46] [47]
The company manufactures cylinders, [4] valves, valve systems, [5] as well as units for compressed air preparation and is increasingly focusing on electronic networking of system parts. Vacuum technology for non-contact transport systems, such as those used in the food industry [ 6 ] is an additional division.
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 ...
