  1. pneumatic

    Pneumatics (from Greek πνεῦμα pneuma ‘wind, breath’) is a branch of engineering that makes use of gas or pressurized air. 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 pneumatic devices. A pneumatic system controlled through manual or automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer alternative to electric motors, and hydraulic actuators. Pneumatics also has applications in dentistry, construction, mining, and other areas.

Webster Dictionary

  1. Pneumaticadjective

    alt. of Pneumatical


  1. Pneumatic

    The pneumatics were, in gnosticism, the highest order of humans, the other two orders being psychics and hylics. A pneuma saw itself as escaping the doom of the material world via the secret knowledge. Outsiders could only know these secrets by joining a gnostic group. To be gnostic is to believe in three planes of existence: the pure unknown, the material world of coitus and comfort, and the pure spiritual realm of ascension or escape.
