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.

Working Mechanism:

• 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.

Frequently Asked Questions:

Q. What are the points to remember while installing Speedaire 4B237 electric air compressor?

A.

• The electric air compressor should be placed in a location having required cooling airflow & ambient operating temperature.
• The exhaust heat generated should be removed using ducts.
• Area around the compressor should be kept clean.
• Pressure dew point of the exiting compressed air should be checked to determine proper installation.

Q. What are the factors used to choose the right electric air compressor?

A.

• Total CFM or the airflow rate required.
• Duty cycle or compressor working hours.
• Required air pressure.
• Electrical specifications like voltage, phase & current.
• Compressor tank size.

Q. How often does Speedaire 4B237 stationary air compressor require maintenance?

A.

• Oil level in the compressor needs to be checked daily along with draining the tank of any moisture collected.
• Air filter, safety valve and the unit need to be checked & cleaned weekly.
• Belt rotating the flywheel of the compressor needs to be checked for tightness at least once a month.
• Lastly, the oil needs to be changed / refilled in the compressor once a month.
