Features
Excellent water removal efficiency; Unique deflector plate and shroud creates a swirling of the air stream ensuring maximum water and dirt separation; Large filter element surface guarantees low pressure drop and increased element life.

Important Notice on

How We Rate Our Filters:

If the filter is sized correctly, that is, at 90 PSI entering the unit, a pressure drop of 2-5 PSI creates a swirling action. This centrifugal action causes the removal of liquids and large particles before the air then enters the filter element where smaller particles are filtered out. That is why Parker Filters are so effective at water removal. All the Filters rated here in this section are at 90 PSI inlet, 5 PSI pressure drop, the optimal condition for water and particle removal.

In October 1998 Parker issued their Tech Bulletin FRL-TEC-6 that listed 80 chemicals known to attack filter bowls and sight gauges. That convinced us, for eye protection for all our customers we would only sell Economy and larger filters [and lubricators] with bowl guards. If you would like a copy of FRL-TEC-6 please do not hesitate to ask us.

(Spitter Drain)

The diaphragm in this drain pulses when there is a pressure differential such as a valve cycling or cylinder stroking downstream. This action flexes the diaphragm and allows the filter to drain the entrapped water.

The float internal to this drain rises with increased liquid level. When the float rises, it opens a seat area allowing the trapped liquids to drain through the bottom.

A manual override can be pushed in the bottom of the drain to unseat the float if particulates create a block.

Once the required flow is determined for a pneumatic application, the filter can be selected by using the flow chart. To read the filter flow chart, first determine the  inlet pressure that will be used. Find the appropriate pressure curve on the graph.

Each graph twill contain three pressure curves. If the required inlet pressure is not on the graph, Interpolate a similar curve for the required pressure.

Next, determine the acceptable pressure drop across the filter and locate it on the vertical axis. Find the intersection point of the acceptable pressure drop and the inlet pressure curve.

At this point follow a vertical path downward to view the flow in SCFM. If the flow is too low, select a larger port size or body size to give the required flow, if the flow is higher than necessary, select a smaller port size or body size to give the required flow.
