Abstract
An air compressor apparatus is disclosed that includes an air tank. A first compressor assembly can be fluidly coupled to the air tank, the first compressor assembly including a first head unloader valve. A second compressor assembly can be fluidly coupled to the air tank, the second compressor assembly including a second head unloader valve. A control unit can be electrically coupled to the first and second compressor assemblies, the control unit operable to control the operation of the first and second compressor assemblies. During startup, the first and second air compressor assemblies can be configured to draw less than 20 amps of current combined from a single 120 volt power source. The first and second compressor assemblies can each be dual piston compressor assemblies.
Claims17
An air compressor apparatus comprising:
- an air tank;
- a first dual piston compressor assembly fluidly coupled with the air tank, the first dual piston compressor assembly including a first head unloader valve;
- a second dual piston compressor assembly fluidly coupled with the air tank, the second dual piston compressor assembly including a second head unloader valve;
- and
- a control unit electrically coupled to the first and second dual piston compressor assemblies, the control unit including a switch moveable from an open position to a closed position to simultaneously provide power to the first and second dual piston compressor assemblies;
- wherein each of the first and second compressor assemblies includes a first and second head outlet, a pneumatic line is fluidly coupled between the first head outlet and the air tank, the first head unloader valve is coupled to the second head outlet of the first compressor assembly, and the second head unloader valve is coupled to the second head outlet of the first compressor assembly;
- and
- wherein the first and second head unloader valves are biased in an open position, the first head unloader valve is configured to move to a closed position after a predetermined pressure is built up in the first dual piston compressor assembly, and the second head unloader valve is configured to move to a closed position after a predetermined pressure is built up in the second dual piston compressor assembly.
An air compressor apparatus comprising:
- an air tank having a tank inlet;
- a dual head check valve having a first inlet, a second inlet, a check valve outlet, and an unloader port, the check valve outlet fluidly coupled to the tank inlet;
- a first dual piston compressor assembly fluidly coupled to the first inlet of the dual head check valve;
- a second dual piston compressor assembly fluidly coupled to the second inlet of the dual head check valve;
- an exhaust unloader valve fluidly coupled to the unloader port of the check valve;
- and
- a control unit electrically coupled to the first and second dual piston compressor assemblies to control operation of the first and second dual piston compressor assemblies, the control unit configured to control actuation of the unloader valve to selectively release air from the first and second dual piston compressor assemblies through the exhaust unloader valve;
- wherein each dual piston compressor assembly includes a first and second head outlet, a pneumatic line fluidly coupled to the first head outlet and the air tank, and an auxiliary pneumatic line fluidly coupled to the second head outlet and the pneumatic line.
An air compressor apparatus electrically connectable to a single 120 volt power source, the air compressor comprising:
- an air tank;
- a first dual piston compressor assembly fluidly coupled to the air tank;
- a second dual piston compressor assembly fluidly coupled to the air tank;
- and
- a control unit electrically coupled to the first and second dual piston compressor assemblies, the control unit including a switch moveable from an open position to a closed position to simultaneously provide power to the first and second dual piston compressor assemblies;
- wherein when the apparatus is electrically connected to the single 120 volt power source and the switch is moved to the closed position, the first and second dual piston compressor assemblies combined draw a current of less than 20 amps from the 120 volt power source during startup.
