aircontrolled

Aircontrolled is an adjective used to describe devices, systems, or mechanisms whose action is governed by compressed air. In engineering, such systems are usually categorized under pneumatics and use air pressure to perform work. The term contrasts with hydraulic systems, which use liquids, and with electric or electro-mechanical drives.

Aircontrolled systems operate by supplying compressed air through a network of valves, regulators, and sensors. A pneumatic actuator converts the energy in the compressed air into motion—typically a piston or diaphragm producing linear movement, and in some cases rotary motion via vane or piston actuators. Control logic is implemented with solenoid valves, pilot valves, and valves arranged in logic circuits; exhaust and lubrication may be included. Filtration and moisture removal are important to prevent corrosion and sticking.

Advantages include simple construction, clean operation, fast response, and suitability for hazardous environments where sparks must be avoided. They are often lighter and less costly to maintain than hydraulic systems. Limitations include lower force density compared with hydraulics, potential energy losses due to leaks, and dependency on a reliable compressed-air supply. Performance can be sensitive to air quality and temperature.

Common applications include manufacturing automation, clamping and gripping devices, pneumatic brakes on heavy vehicles, door actuators, and HVAC air dampers. In some industries, “aircontrolled” may appear as marketing shorthand for components that are operated by air pressure rather than electricity.
