Guides to make an air compressor from an old refrigerator

Today we will discuss a useful way of making an air compressor from an old refrigerator with a step-by-step guide. It’s a straightforward process, so any hobbyist can apply it and get a positive result.

The tools you will require:

  • 110volt refrigerator
  • Recoverable compressor and tank
  • Safety release valve
  • Some length of 3/8 I.D
  • Some fittings
  • An air hose
  • And an air gauge

Evacuate the entire refrigerant

It is vital to remove all the parts properly from donor refrigerators. You can do it for free at many shops. During the removal process, check whether the compressor is running or not.

Chopped the copper tube

Once removed the entire gas, cut the copper tubes using a tubing cutter. You will find one ingoing and one outgoing preserved compressor module. Make sure you have left a length of the copper tube. Besides, don’t rotate the unit down while cutting.

Mark the wire and terminal

Now trace the wire from the power cord into the cabling connects throughout the divide fatals on the capacitor. Use masking tape to mark the terminal and wire to maintain proper configuration.

Prepare a note of wire at this place that will run to other set of terminals on the sealed compressor module. You have marked this terminal and the wires too.

Connect power cord

Remove all the wires except the pump and capacitor and attach matching power cord cables to the capacitor. Make sure you have connected the green ground cable to the bottom pump of the air compressor.

Bend the copper line on the pump

Now bend smoothly and carefully both the copper lines vertically on the pump and make sure you don’t bend them. Make the air pump unite secure so it can prevent pulling wires lose while walking from shaking.

Check the motor sound

Shift the pump far away from the wall or ceiling and don’t keep anything close to 15 feet of the pump. Now power on the motor and listen to its sound. If the motor doesn’t run, then power off it and recheck its power cord wire connection. It can happen if the copper tube discharges oil. Don’t worry; just mark the discharger as the deliver line.

Check the copper line

If you don’t find any oil blowing, then put your fingertip on the copper line’s end and you may feel a smooth vacuum. Still, you have to mark the copper line as a supply line.

Attach other accessories

Now attach a smaller air hose to the supply line and fasten it to a 1/4″ npt fitting attached to a 4-way “tee” with a release valve, 120 lbs or larger air gauge with a three-way “tee” with a 10-gallon air tank. Then attach a fast connect air chuck to one of the legs of a three-way “tee”. It will help you attach the air tool or inflate the vehicle tire.

Secure the pump

Use a strong cart or other sturdy frames to secure the pump, maintaining the unique rubber mounts and stage. Make sure you have mounted the air tank near the pump. Now clean the area and insulate the safety valve, wiring, and route air equipment to the gauge and fast join assembly. At last, your new and best air compressor is ready for further use.
