Principle of Operation
On startup, air and non-condensible gases enter
the trap and are automatically vented through an
accurate balanced-pressure internal thermostatic air
vent. As condensate enters the trap, the float and
lever mechanism is raised, lifting the valve off the
seat, discharging the condensate. Condensate will
continue to be discharged at the same rate at which it
is entering. Any air or non-condensible gas that may
accumulate will be continually and efficiently passed
by the thermostatic air vent.
