Air Compressor - The primary function of air compressor is to generate a compressed air into the system that requires air supply to operate. Some drivers mistakenly identify engine air compressors as air condition compressors. Engine air compressors does not have magnetic clutch.
Air pressure regulator - regulators are required to primarily regulate the pressure given into the air dryer to avoid unnecessary burst of air pipes and lines.
Air dryer or air purifier - The air generated from air compressors includes oil (from the engine) and moist (water vapor). Air dryer purifies the generated air and removes oil and water substance.
Four-way valve - Valve that controls the direction of compressed air to serve the front and rear brakes, the parking brake and accessories attached to the system such as front and rear door cylinders.
Air Reservoir tanks - Compressed air are stored on these tanks. These may be coupled with other sensors or one-way valve to restrain the compressed air flowing back into the four way valve.
