Air balance pipe
For GESTRA air traps UNA 14 P we recommend the installation of an air balance pipe K in order to
equilize the pressure. The air balance pipe ensures a continuous condensate flow from the fluid line
to the trap and effectively prevents the formation of water pockets.
Unfavourable piping geometries and certain positions of installation may also require the installation
of an air balance pipe for steam traps. The air balance pipe effectively prevents the formation of
water pockets.
