Δ Brief Introduction : The KARFAR model FGP4X air vent  is double orifice type.
This air vent is usually mounted at outlet side of  pump or water distribution pipeline. It performs to release the air collected inside so as to improve the working capacity of pump station and pipeline. When the pipeline is under negative pressure, the plug will  open rapidly to fill in air to protect pipeline from negative pressure damage.

Note: This model can not be used in sewage pipeline

Features:
1, 
Reliable sealing performance due to advanced design
2, Automatic air releasing and filling without manual operation
3, Dependable performance and long service life
   Float ball moves in fixed routine without hitting the shell
4, Short in height than other same kind air vents

Three functions: 
1, large amount of air releasing
2, small amount of air releasing
3, rapid air filling
