SPEEDAIRE 4B237 Electric Air Compressor 3 Hp

Speedaire 4B237 stationary air compressor is an electric-powered pneumatic device that produces & stores compressed air in a storage tank. This Speedaire air compressor is ideal for pneumatic devices like inflation equipment, tire changers, nailers, pneumatic controls & spray guns in the automotive, food & beverage, medical, petrochemical and pharmaceutical industries.

• Choose a clean, well-ventilated location having enough clearance between the compressor flywheel & walls to install the unit.
• Mount the tank over the concrete floor or isolation pads to reduce vibrations.
• Place the motor & compressor over the tank using suitable accessories. Connect the motor, compressor & tank using belt drive flywheel & piping connection.
• Connect the motor to a grounded electrical connection.
• After the power is switched On & the motor starts up, the connected flywheel starts rotating to start up the compressor.
• The compressor's cylinder crankshafts & pistons start moving up & down to intake air.
• The pressurised gas is sent to the air cylinder / tank for further applications. An appropriate filter should be installed to receive air free from water or oil.
• The unit is controlled using an automatic start & stop pressure switch that stops the compressor once a preset receiver tank pressure is reached. When the receiver tank pressure goes below a preset minimum level, the pressure switch restarts the compressor pump again.

• It includes essential components such as a manual drain valve, oil sight glass, pressure gauge and pressure safety valve, facilitating convenient maintenance and ensuring operational safety.
