The most important maintenance procedure for an air compressor is to clean out the compressor tank. We’ve provided a step-by-step process on how to clean out your air compressor tank. Hopefully, you understand how to clean an air compressor tank and this guide will help you to clean without any damage to the tank.
As pressure builds up and compresses air into your air compressor tank, water vapor gets compressed too and can cause water build up, and even rusting of the tanks walls. Though it is not directly advised to put anything into the compressor tank to clean it, I’ve come across a few recommendations to use Evapo-Rust if you’re having rust issues inside the tank. An uncoated inside of the tank will absorb a lot of the heat, which in turn produces a lot less moisture in the tankif you coat that tank the pump will get 4 times hotter than designed, harsh residual chemicals in it will ruin every air tool you use thereafter.
Many people spring clean their homes each year, so we think it’s about time you also try a little air compressor spring cleaning. Reciprocating air compressors need their air filter element looked over as part of every seasonal check, so that includes your air compressor spring cleaning to-do list. When looking past your air compressor spring cleaning, it’s smart to consider creating a preventative maintenance checklist that you use ensure the health of your air compressor all year long.
The tank does not look rusted outside and the compressor looks to be in good condition. A local repair shop told me that the rust is normal, and said I could flush it by opening the top tank brass flare nut, fill near to top with Simple Green and water, etc. I assume the former owner did not drain the tank enough and that is the reason for the rust.
Normal in any compressor tank, IMHO. 01-20-2015, 5:17 AM #7 We call it mayonnaise,and like posted above it’s blow by oil from compressor head mixed with moisture. The key is that if the tank does split on test under water pressure it won’t explode as it would if filled with air – the pressure is instantly released because the water does not compress….

After cleaning out and testing/proving the tank make sure there’s a working pressure relief valve on it, and that the pressure/start/stop and power switches are working.
Back in loose, and then tie it in the back of your pickup truck and take a long drive down a bumpy road. This is a motorcycle gas tank trick, which is often done by tying pillows around the tank and sticking. Tumble the tank at 10 RPM end over end with a shovel full of sharp aggregate inside adding a gallon of water and some laundry detergent to correct PH and keep stuff in suspension. 01-02-2013, 08:55 AM #12 We watched a tank company clean a tank interior last month, suprisingly low tech.
best way to clean air compressor tank inside Related Question:
How do I get rust out of my compressor tank?
There’s one relatively safe thing you can do to remove rust. Do it with phosphoric acid. Unlike HCL (muriatic), it won’t damage the tank. If you have any chemical supply houses nearby, you may be able to buy it in a 5 pint bottle.
Do air compressor tanks rust out?
Air-compressor tanks are especially prone to heavy rust and corrosion, especially if they’re not taken care of properly.
Does compressed air Remove dust?
Compressed air is powerful and can be dangerous—even deadly—when misused. Air compressors aren’t designed for cleaning, but it’s still common practice to clean the dust and debris from filters, machinery, workshop surfaces, clothes, and so forth using compressed air.
Does compressed air get rid of dust?
You can blow compressed air around and dislodge the dust that settles on intricate objects and the top surfaces of books’ pages (which seem to cling to it no matter what you do). It will take nearly all the effort out of the chore.
What happens if you put too much oil in air compressor?
While the dangers of too little oil are obvious, it’s also important not to overfill a compressor with oil. If the oil level is too high the oil can get whipped and it will foam up, losing some of its lubricating properties. In addition, it will gain volume, further increasing your problems.
What causes oil to in air tank?
The main causes of oil carry-over are excess oil in the reservoir, low temperatures, faulty separator filters and scavenge lines, and oil degradation. Issues can be prevented by monitoring your compressor’s temperature, checking the separator filter and scavenge line, and replacing the oil once a year.
How do I know if my air compressor needs oil?
In the middle of the sight glass, you will see a dot. Ideally, you want the oil level to be in the center of the dot. If the oil level is below the dot, your unit needs more oil. If the oil level is above the dot, you have added too much oil.
Are old air compressors worth anything?
If you purchased or have a reliable back up compressor then sell the old compressor on any social or online auctions like craigslist for local listings or ebay for online auctions. A good rule of thumb would be $100 per 1 hp for good condition or $125 per 1 hp for great condition.
Do air compressor tanks explode?
Yes, air compressors can blow up. Air compressor explosions are most commonly caused by substantial corrosion of the compressor tank. Excessive condensation leads to corrosion, and you can avoid this outcome by monitoring and servicing the compressor and its auxiliary components.
How long do compressed air tanks last?
Carbon fiber air tanks, or fiber wrapped tanks are required to be rehydro tested every 5 years and have a 15-year life span. Aluminum tank hydrotesting needs to be done every 5 years however these tanks can continue to be retested until they fail.
How often should an air compressor tank be inspected?
(a) All air tanks requiring a permit to operate shall be inspected internally and externally at least once every 3 years for portable tanks and once every 5 years for all other tanks by a qualified inspector.
Should an air compressor be drained?
Even if your air compressor’s pump cycles only a handful of times per day, you should drain your compressor tank every other day or several times per week to prolong its operating life and to protect your pneumatic devices and equipment.
