Servicing Procedure for Coalescing Filters
All coalescing filters are equipped with an automatic
drain from which accumulations of entrapped liquids
are automatically blown out. The filter element should
be replaced when the leaving air pressure gauge
(mounted on the PRV station charcoal filter head)
indicates less than 50 psig (350 kPa) the differential
pressure between the leaving and input gauges is
15 psi (105 kPa) or more, or after one year of service—
whichever occurs first.
