Background
The Craftsman Air Compressor 921.166420 is a 20-gallon, 1.5 HP, oil-free, direct drive air compressor. It is designed to provide a source of compressed air for various tools and applications. The compressor is equipped with a regulator that controls the air pressure coming from the air tank. It also features a quick connect system for attaching and removing the air hose, a tank pressure gauge that indicates the reserve air pressure in the tank, and a pressure switch that controls the power to the motor and the cut-in/cut-out pressure settings.
The air compressor also includes a tank safety valve that allows excess tank pressure to escape into the atmosphere, a pressure relief valve that releases compressed air when the air compressor reaches cut-out pressure, and a tank drain valve for draining condensation from the air tank. Additionally, it has an air intake filter that provides clean air to the pump and a check valve that closes to retain air pressure inside the tank when the pump is not in operation. The air compressor is designed to be reliable and durable, with a focus on repairability and longevity.
