#compressed air

• Airlift — A technical installation, pump, or device based on the principle of pneumatic transport, used to lift a liquid or a mixture of water and sediments through a vertical pipe by injecting compressed air at the base. This system is widely used in aquaristics for water filtration, in petroleum engineering, and in dredging operations due to the absence of moving mechanical parts.
• Aeromotor — A mechanical device, motor, or complex technical installation that transforms the kinetic energy of air currents or wind into directly usable mechanical energy or electrical energy. In a broad structural sense, the term includes everything from high-power modern wind turbines to traditional windmills or pneumatic motors driven by compressed air.
