Why Should I Drain My Air Compressor After Every Use?

If you leave the compressor without draining after using, this water vapor might get accumulated which may lead to internal damage to your air compressor structure.

Why Should I Drain My Air Compressor After Every Use

Inside an air compressor tank, a moisture-resistant coating is provided to protect it from corrosion. Otherwise, it would result in water to steel contact and damage the internal part of the tank. This depends on the humidity of the air. If you live in a relatively humid place, the rate of condensation of water vapor is higher inside of the compressor. They are stored at the bottom of the tank.

As time passes, water may build up from the vapor and you might find your compressor is pushing out droplets of water. This internal water picks up dust and other unwanted residues easily from the air and also from the inner components of the tank.

All of these dust materials may react with each other and thus damage the protective coating. Gradually, this degradation of the moisture-resistant coating leads to rust inside of the air compressor and affects the tank integrity. This is why you should not take any chances and drain your compressor after you use it each time.

Step 1: At first, you have to make sure that you have turned off the air compressor. You can do this by simply turning off the switch of the compressor towards the off position. Besides, to be more cautious you can unplug the whole unit and bring it to a state where the energy level is zero. In this way, you will be safe from any kind of threat posed while you’re working on it.

Step 2: During the second phase, you have to decrease the pressure level inside the tank. Take it less than or equal to about 10 PSI. You will find a ring near the safety valve of the tank. Pull the ring and the internal pressure within the tank will be released.

Place your one hand on the tank valve and keep pulling it to release pressure. While you do this, use your free hand for deflecting the air. Maintain this posture till the air compressor tank is emptied completely. One thing you should be careful about is that the released pressure can cause dust to fly into your eyes. So wear eye protection while doing the task.

Step 3: Now, locate the air compressor drain valve. This valve is usually situated at the lowest part of the tank. Once you have located it, now open the drain valve. As a result, any type of moisture inside your air compressor tank will be allowed to escape.

It will be very good if you tilt the tank so that if there is any moisture remaining inside of them will be drained out fully. Finally, when you have finished draining your air compressor, close the valve. And now, you can again use it as normal.
