Drain your Air Compressor for Proper Storage
Air compressors are integral to a lot of home projects. Most recently, I used one for laying hardwood flooring. Taking good care of your compressor means it will work consistently and last longer. There’s lots of preventive maintenance to keep your compressor in good shape but this post will focus on properly draining moisture from your air compressor.
Why Draining an Air Compressor is Important
Compressed air systems create condensation that accumulates in the tank. The amount of condensation depends on how long you’ve been running the compressor and the humidity of the air. This condensation often contains water, dirt, lubricating oil and other substances. If you don’t drain your tank, this accumulation will ultimately corrode (rust) the inside of your tank, weakening the tank walls until it ruptures. Be sure to drain your tank after every use.
How to Drain an Air Compressor
Properly draining your compressor is very simple. These steps are not meant to replace your owners manual.
Step 1: Turn off your air compressor and unplug it.
Step 2: Turn the regulator knob counterclockwise to set the outlet pressure to zero.
Step 3: Disconnect any air tools or accessories.
Step 4: Prop up one side of your compressor so that the drain valve is the lowest point. Setup some kind of drainage pan if you’re concerned about the surface underneath your compressor.
Step 5: Open the drain valve part way. Air and condensation will start shooting out. As the pressure drops, open the valve the rest of the way.
Step 6: After it’s finished, close the drain valve. Store your compressor in a clean and dry location.

Don’t want to spend the time draining your compressor? You’ll pay in the long run, as this can shorten the compressor’s life by half. Take proper care of your compressor, and save your hard earned bucks for other reconditioned tool purchases.
