I bought a compressor but attached it in the immediate vicinity of an air gun to avoid moisture on the electronic equipment. Satisfied because it is small and light. Although the drainage of the accumulated water is manual, it is not an obstacle because it is at hand.
It is installed and used just before the tool for removing water from the air compressor. Although it is a simplified type, it seems that moisture is removed securely. When using an air gun without a filter, moisture will blow out like a mist from the nozzle. Since the compressed air is released into the air all at once, the amount of water contained in it is not stupid. For long-lasting air tools, I would like to use a moisture removal filter as a minimum care.
I used it for air suspension. I am satisfied with the separation of the rough moisture. However, it is nice that bolts are out, but because the shape was not straight, it was a bit disappointing. Even though I looked into it, things were nice.
