Pneumatic equipment is powered by compressed air. Pneumatic tools offer high power and include air guns, grinders, drills, hammers, nail guns, wrenches, and saws. Air compressors supply the power source for pneumatic tools, pumps, and equipment. Compressed air treatment products remove water, oil, and other contaminants from a compressed air stream. Pneumatic actuators convert compressed air into mechanical motion. Pneumatic motors are nonsparking for use in hazardous environments. Pneumatic coolers and air knives produce focused air to cool or dry materials. Lifting bags elevate and position heavy loads when inflated with compressed air. Pneumatic system components facilitate the operation of pneumatic equipment. Vacuum system components lift and move workpieces in automated systems. Pneumatic valves control air pressure and flow rate in pneumatic systems. Pneumatic filters remove contaminants in pneumatic systems. Vibration-isolating air springs provide isolation and actuation in automated systems.
