How to drain an air compressor?
Taking proper care of your air compressor includes draining it as needed. But the question is, how to drain air compressor? All air compressors feature a valve that you can use to drain your air compressor. It’s called a drain valve. The valve comes in different sizes and shapes depending on your air compressor model.
How do I drain the pressure from my HVAC system?
Turn off the compressor to drain the pressure. Leave the hose in place until the compressor is turned off. Twist the pressure regulator knob near the hose to shut off the hose's air supply first. Then turn off the compressor and wait for the pressure to leave the system. Pull the pressure relief valve to speed up draining process.
How do you fix condensation on the inside of a compressor?
Twist the valve counterclockwise so that the pressurized air blows out any collected moisture. Put the valve back in place by twisting it clockwise until you can no longer hear the air flow. [12] If you can’t twist the valve by hand, try using pliers. To keep your compressor functional, drain the condensation after every use.
Where is the drain valve on a compressor?
Before you can use the valve to drain your compressor, you must decrease the machine’s internal pressure. The pressure level should be somewhere below 10 psi. Now that your compressor is ready to be empty of water locate the drain valve. As I’ve mentioned before, the drain valve is located somewhere at the tank’s bottom or lower side.
How does an air compressor drain valve work?
As water builds up in the tank, it flows into this housing. The rising water level causes a float inside the housing to rise. Upon reaching a pre-set level, the float triggers the drain to open, and the water drains out. Some compressed air is lost with this type of valve.
Should I leave the drain valve open on my air compressor?
If unit will not be used for a while, it is best to leave drain valve open until such time as it is to be used. This will allow moisture to completely drain out and help prevent corrosion on the inside of tank.
How do I drain the air out of my air compressor?

How do drain valves work?
A drain valve is a mechanical device used to release excess or unwanted quantities of liquid or gas from a storage tank, vessel or container. The valve is usually opened by turning a screw or handle, although some drain valves are automatically opened when a set pressure or temperature is reached.
What is the valve on the bottom of an air compressor?
A condensate drain valve is a small device typically located at the bottom of a compressor's air receiver. Whether the air compressor drain valve is open or closed determines if water flows out of or remains inside the compressor tank.
Why does my air compressor make so much water?
As the compressed air cools down, it can no longer hold the same amount of water vapor, so the extra water gets forced out of the air in liquid form. By the time the air has cooled to the temperature range typical for pneumatic tools, which is about 120° F. and below, quite a bit of water has formed.
How long can you leave air in an air compressor?
Depending on the size and type of compressor, air compressors can be left running anywhere from a few hours to 24 hours a day, seven days a week.
Do air compressors refill themselves?
Every time you use your power tool, the tank's pressure will drop as that compressed air goes through the hose to your tool. When the pressure in the tank drops too low, the compressor will kick back on, refilling the tank.
How often should you drain 60 gallon air compressor?
If you use your tank daily, we recommend draining it once every couple of days. You should be doing everything you can to prevent major rust if you drain it once a week.
How do I winterize my air compressor?

How do you store a compressor?
Find a clean, dry location to store your compressor where you can maximize space efficiency. You should almost always opt to store your compressor indoors, unless you can guarantee your compressor is stored in an outdoor area with a stable, regulated temperature and proper insulation.
How to use an air compressor?
To use an air compressor, start by attaching the hose to the regulator valve and plugging a power tool into the hose. Then, plug in the air compressor, turn it on, and wait for the needle on the pressure gauge to stop moving. Next, adjust the pressure regulator knob so it matches the pressure listed on your power tool.
How to turn on a compressor?
Turn on the compressor and wait for the tank to pressurize. Flip the electrical switch on the tank to turn it on. The machine will buzz to life. Watch the larger pressure gauge on the tank's side. Wait for the needle to stop moving, signifying that the air inside has reached the maximum pressure.
How to check if a compressor is working?
Pull on the safety valve to test it. Look for a copper-colored plug near the hose line. It will be tightly in place on the compressor and may have a ring that makes it easier to pull. Tug it towards you to release the valve and listen for the hiss of escaping air. Push the valve back in place before starting the compressor.
How to attach 2 air hoses together?
Instead, get another air hose and plug it into the first one. To attach 2 hoses together, slide the plug end of 1 hose into the receiving end on the other hose. It works the same way as attaching a power tool to the hose. Extension cords aren’t recommended because they can cause the compressor to overheat.
How to attach a pressure regulator to a compressor?

What happens if you don't drain a tank?
By not draining the tank, you risk rust building up on the inside which will weaken the metal. At some point, the rust will compromise the integrity of the tank and when pressurized will explode. The tank will not go off like a bomb, but rather explode outward at the weakest point.
How to reduce pressure in a tank?
You need to reduce the pressure inside the tank to below 10 PSI. You can do this by pulling the ring located on the ASME safety valve.
