You know your machine is an air compressor when it comes with an air tank. It may be large or tiny depending on the model, but it has quite an important role to make all put together. Some of you might not know the ins and outs of an air tank & conducting it, like how often to drain air compressor tank or how to drain the air, it is important for us to know.
An air tank is built-in with an air compressor to actually store the air & release whenever needed. It provides the pressure into the air tools so that it can lead the force into the accessory or product you’re using.
You may need different air compressors with different tank sizes for various purposes. Check out our air compressor under $500 reviews to choose the air compressors with your expected tank size. Although making the right use of the tank is far more important than your tank sizes.
How Often To Drain Air Compressor Tank
One of the most asked questions on our website is how often should I drain my air compressor tank. And people also asked that should they drain air compressor after every use? Some people reserve the unused air within the tank for later use, some people release it right after their job is done. You might think there’s actually no harm in reserving the air for a long time, but actually, there is!
You might be wondering where does this moisture come from all of a sudden. As you know, water vapor is a significant part of air. So whenever you draw in air into the compressor, water vapor also goes in. The machine then compresses the air, as a result the vapor turns into water which remains in the tank. So that’s how the compressed air in the tank boosts the risk of rust formation.
Anyways, how frequently you should drain your air compressor will depend entirely on how regularly you use your air compressor. If you use your air compressor daily, we would recommend to drain the air compressor once every couple of days. Draining the air compressor is not that important as you’re utilizing the air the very next day. That way you don’t have to waste the power to fill it all over again.
But if you do not use your air compressor regularly, draining is actually important this time. Because the stored air will be in there for a long time, increasing the chances of rust formation. So we would suggest draining the air compressor right after you use it. It might be a little bothersome having to fill it all over again, but it saves your machine!
Although, if you buy an air compressor with a stainless steel tank, you won’t have to worry about rust or anything else. If you want to get a steel tank air compressor, you can consider purchasing the California Air Tools 20020 Ultra Quiet & Oil-Free Air Compressor to avoid all this mess. Apart from being durable, it provides a pretty incredible performance which will serve your purpose quite well.
Many of you might be wondering how to drain the air compressor tank. It’s easy. So let’s dive into a tutorial for that—
How To Drain Air Compressor Tank
Releasing the air from the air tank, however, is not easy for everyone. Because different models have different ways of doing so. But the basic steps are the same for all the compressors. Let’s see how to release air from air compressor—
Turn Off The Air Compressor:
The first step will be turning off your air compressor. You can’t drain the air compressor continuing to fill the tank with external air. Switch off the machine or unplug it.
Reduce The Pressure:
The second step is to reduce the internal pressure of the tank. This can be done by simply pulling the ring on the safety valve. Now you have to find the safety valve of your air compressor to do so. Take help from your instruction manual to locate the safety valve.
When you pull the ring, the tank will start to slowly reduce the pressure and release the air within. We would highly recommend to use a safety glass to prevent any potential injury. You can also do this step by covering the valve with one hand while pulling the ring with your other hand. Continue this step until no more air is coming out & the tank is empty.
Drip Off The Moisture:
The third step is to drain out any moisture from the tank. Your air compressor tank might contain moisture or liquid as it compresses the air. That way, it might compress any vapor or anything volatile to convert it into liquid. This liquid is one of the culprits of making the rust and damaging the tank.
Anyways, you can drain the moisture by opening the drain valve. Not all air compressors have the drain valve in the same spot. So what you have to do is locate the drain valve yourself or with the help of the user guide provided by the manufacturer company.
Open the drain valve and let the moisture slowly drip off. You can tilt the air compressor tank to drain out any remaining moisture within the tank. Make sure to close the drain valve once all the moisture is gone.
And you’re done! Place the air compressor in your reserved place and do it all over once you use it again. Draining the air compressor isn’t actually as annoying as you might think. It’s vital to keep it all high and dry for obvious reasons. So don’t forget to do that.
