Feature
1. This product is designed to be compact and lightweight.
2. In case of a water leak, water can be drained to a drain pan, etc. by connecting a
vinyl tube.
Operation
Principles of air discharge:
1. Upon start-up, the float is in the lowest position
due to gravity and the valve is fully open,
allowing for the rapid discharge of initial air.
2. When initial air has been completely
discharged, the water level rises in the body.
This causes the float to rise, closing the valve.
The coil spring pushes the valve against the
valve seat, keeping the valve closed, providing
a tight seal.
3. When air enters, the water level falls lowering
the float. This causes the valve to open and air
to be automatically discharged through the
valve orifice.
In this manner, the air vent constantly
responds to the amount of liquid flow by
automatically adjusting discharge.
