Cashco 5200P Air Filter Regulator User Manual
Model 5300p, Air filter regulator
SECTION I
I. DESCRIPTION AND SCOPE
These regulators are designed for air service only. Maximum allowable inlet pressure is 290 psi. Operating temperatures
are -20
o
to 180
o
F. The 5300P has low capacity internal relief which provides very limited down stream over pressure
protection. Note: Non-relieving version does not provide internal relief. To avoid exceeding outlet pressure limits in ser-
vice, a pressure-relieving or pressure-limiting device should be provided.
SECTION II
II. INSTALLATION
Install the regulator as close as possible to the instrument or tool it is to service. Clean all pipelines to remove dirt and
scale prior to installation. The words "IN" and "OUT" are cast into the body to indicate the direction of fl ow. For best fi lter
drainage orient the drain valve so that it is at the lowest point on the drip well housing. The exhaust port should be kept
free and unplugged. Position the regulator so the vent is at the lowest point possible, or provide additional protection
to prevent contaminants from entering the regulator. Rotating the bonnet relative to the body may change the vent hole
orientation. Exhaust may be remotely vented by installing tubing to the 1/8" NPT port. Apply pipe compound or sealing
tape to the male pipe threads prior to installing regulator. Use caution to prevent the sealant from getting inside the
regulator.
