Why so much water

As a first time user or a curious person, you might be wondering why the air compressor produces so much water. But, not to worry, in this section of the article, we would be helping you understand better. Air compressors are known to withstand a lot of pressure, which is why they are built from certain types of materials. For this reason, the inner layer of the air compressor has a moisture resistance coating which prevents water from forming on the steel inside of the tanks. What this means is that the moisture or water which was meant to form on the inside of the steel tanks will start developing at the bottom. If you don’t drain it regularly, the excess water could damage things in the air compressor. For example, it can cause rusting in the tank, which is something you should try to avoid.
