The Need for a Pressure-balancing Line
This air trap is designed to automatically discharge inflowing condensate. However,
if the condensate completely fills the inlet path of the trap, air in the trap body will not
be able to escape, preventing the displacement of air by condensate, and thus
preventing condensate from entering the trap. This phenomena is called air binding.
A pressure-balancing line installed between the trap cover and the dry portion of the
receiver tank is used to prevent this phenomenon from occurring.
Connect the pressure-balancing line in the follow manner:
