Air Compressor Replacement Parts

An air compressor is a mechanical device that converts power into potential energy stored in compressed air. It works by pulling in air, compressing it, and storing it in a tank under pressure. This compressed air can then be used to power tools like nail guns, spray painters, impact wrenches, and more—making it essential in workshops, construction, and industrial settings.

Key components of an air compressor include the motor, pump, air tank, pressure switch, and regulator. The motor drives the pump, which compresses the air. The air tank stores the pressurized air until it's needed. The pressure switch controls when the compressor turns on and off, while the regulator adjusts the air pressure going to the tools for safe, efficient operation.

Common issues with air compressors include air leaks, faulty pressure switches, worn-out valves, or overheating motors. Regular maintenance, like checking for leaks, draining the tank, and cleaning filters, helps prevent breakdowns. At WholeToolBox, we offer premium air compressor parts, including repair kits, discharge tubes, capacitors, compressor heads, valve plate assemblies, low-pressure ring piston 4" assemblies, and more—all at reasonable prices.

FAQs

How do I know if my compressor capacitor is bad?

Signs include the motor not starting, humming but not running, or tripping the breaker. A multimeter test can confirm failure.

What are signs of a faulty check valve?

Symptoms include air leaking from the unloader valve after the compressor shuts off or trouble restarting under tank pressure.

How often should a compressor safety valve be tested?

Test at least once a year by manually pulling the ring to ensure it opens and reseats properly.

Why is my safety valve leaking air?

It may be stuck open due to debris, worn out, or the compressor is consistently over-pressurizing.
