There are a few different ways to do this, but the most common is to use a dehumidifier.

A dehumidifier removes moisture from the air by cooling it down and condensing the water vapor into liquid form. The condensed water is then collected in a bucket.

Step 1: Gather Supplies and Tools​

Gather supplies such as a dehumidifier, hose, and drain bucket. You’ll also need the following tools:

  • The screwdriver opens up the air compressor’s motor compartment.
  • Philip’s head screwdriver or ratchet is recommended to tighten and loosen screws.

Step 6: Install Dehumidifier Now

It’s time to install the dehumidifier. First, remove the drain hose from the drain pan and attach it to the dehumidifier’s drainage outlet. You can place the other end of the hose in a bucket or container to collect the condensed water.

Attach the dehumidifier’s power cord to an outlet and turn it on. The dehumidifier will start to remove moisture from the air.

Step 7: Monitor the Dehumidifier 

Monitor the dehumidifier to make sure it’s removing enough water from the air. If it’s not, you may need to adjust the settings.

Once the water tank is full, turn off the dehumidifier and empty the tank into a sink or outside drain. Repeat this process until all of the water has been removed from the air compressor.

Reattach the top of the compressor, making sure to place each screw back in its original spot. Reconnect any disconnected hoses and screw the drain pan back in place.

You need to turn on the air compressor and check for leaks. If you do everything correctly, you’re good to go!
