Should Your Air Compressors Be Winterized?

As the temperature starts dropping and the snow begins to fall, it’s time to inspect and look at winterizing your air compressor in order to ensure that it will be in great condition for the colder months that are coming.

Weather maintenance for your air compressor

We would recommend biannual maintenance to prepare for the extreme temperatures, One towards the end of spring and the other one towards the end of fall. During these times you will need to perform the following steps on your air compressor:

Inspect the insulation – Another sign of trouble is when the heat starts to leak from your compressor system.

Inspect the weather stripping – If there are any signs of wear and tear visible on the stripping, it should be replaced immediately.

Inspect your drains and openings for air intake – In order to ensure maximum protection from the rain and snow, the drains and openings need to be in good shape.


Check the tanks for any condensation

During the colder months your tank could accumulate moisture on the inside, and if it is left unchecked, it could freeze if the temperatures drop low enough. You will want to ensure that you inspect the tanks several times every week throughout the winter months to ensure that the condensation is not building up. If the smallest amount of moisture accumulates, you should drain it immediately. Whenever you see any moisture appear within a few days, could be a sign that something worse is happening within your compressor system.

To remove condensation as much as possible, you will want to put the drain on the receiver tank at the lowest possible angle. There are some systems that can drain the moisture automatically and are equipped with test buttons for you to see whether it is working or not.

Winterizing the condensate drains and bowls outside

One of the very common mistakes made is neglecting the outdoor drains during the winter months. When temperatures drop to freezing, you can apply heat trace tape over the exposed parts of the drain line in order to stop them from freezing.

If you aren’t planning on using your compressor in the winter months, there won’t be much need for heat tape as it won’t receive any energy without the system running. In this case, you should drain the water from the lines so that they don’t freeze.
