What is the working principle of the automatic drainer?

Condensate accumulates in the drain reservoir, causing the float to rise and force air out through the tube to expel liquid. Once expelled, the float returns to the low position, closing the valve until the cycle repeats.

What are the main applications for this automatic drainer?

It is used in air compressors, after-coolers, cyclone condensate separators, pressure vessels, air filters, and air dryers to automatically remove accumulated water.
