Description
Parker P55 Series 1/4” to 2” NPT
Air coalescing is a continuous, balanced, steady-state process occurring at or below rated flow, which depends on two factors
for high performance: (1) The bowl must be kept free of waste liquid build-up and (2) The element must be replaced when the
differential pressure reaches 6-10 psid, 12 psid maximum. Differential pressure can be sensed at the inlet and outlet ports
by two gages, or by Parker’s DPG-15HP differential pressure gauge, or by observing system characteristics.
Bowl draining is accomplished by opening the manual drain valve (standard on all housings), at least once every 8 hours depending on the liquid load.
A Parker coalescer, under normal system conditions, will operate for 6 to 12 months before reaching its maximum differential pressure. Parker coalescers are designed for nominal operation with 10-20 wt. oil. Any viscosity increase over that of 20 wt. oil must be offset by a proportionate oversizing of the filter element.
