External Auto Drain

Feature & benefit

1. Energy saving: only drainage, no exhaust;

2. Efficiency: word displacement, low frequency of action, long service life;

3. Reliability: It is best not to have movable parts in the water storage tank. Because condensation is corrosive, there are no movable components in the water tank, which can reduce the failure rate and improve the reliability.

Working Principle
Drains are designed with float ball drain system. The outlet of the drain will close and stop draining if the draining buoyancy is smaller than the float ball's weight and the pressure from the compressed air. It will have a trickle of drainage if the float weight and pressure are balanced. It will open and start draining if the draining buoyance is greater than the float ball's weight and the pressure from the compressed air. It works cyclically according to the buoyancy.

Advantage

1.Automatic drains are often at the lowest end of air compressor piping or other compressed air treatment systems. The advantage is that no manual care is required.

2. Even in places where the space is relatively small and too high, it can also play a good drainage effect.

3.It can prevent the artificial drainage from being forgotten and causing the tight air to be re-contaminated with condensed water.
