H. FILTER/REGULATOR ASSEMBLY
The purpose of the filter is to remove bulk liquids and solid particles from the compressed air stream. The filter
element provides mechanical separation of solids. Centrifugal force inside the filter bowl separates bulk liquids
and larger solid particles.
The filter consists of a louver, which causes a centrifugal spinning action to separate contaminants. A filter, which
mechanically separates contaminants is also present. The filter bowl collects the contaminants and a baffle
prevents turbulence from picking up contaminants at the bottom of the bowl and returning them to the air stream.
1. Filter Maintenance
a. To remove filter element...
Twist the filter bowl 1/8 turn clockwise (CW).
Then pull the bowl down to expose the filter element.
To remove the filter element, unscrew the baffle
(this will allow element removal).
b. To clean filter element...
The filter element can be cleaned with soap and
water.
NOTE: When replacing the filter element bowl, care
must be taken to ensure that the O-ring
does not get pinched.
2. Regulator Operation
The adjustment knob simply acts upon a spring rest located on the spring and directly compresses the spring
as it is adjusted. A non-rising low torque adjustment screw is used on this type of filter and regulator. The
upper spring rest is located on top of the regulator spring and transmits force from the adjustment screw to
the spring. Regulators use simple wire coil springs for controlling the downstream regulator pressure. The
bonnet houses the adjustment spring and is used to help retain the diaphragm. The diaphragm moves up
when the downstream pressure reaches its preset pressure level, which in turn closes the valve. A self-
relieving regulator is designed to automatically relieve overpressure in the secondary side of the regulator.
NOTE: THIS SELF-RELIEVING FEATURE IS NOT DESIGNED TO BLEED THE
DOWNSTREAM PRESSURE.
Dryer must be provided with a clean, dry, regulated 80 PSI +/- 10 PSI (5.51 bars +/- 0.68 bars) air supply
(equivalent volume = 9 cfh [.26 cmh]).
The regulator should be set at 80 PSI +/- 10 PSI (5.51 bars +/- 0.68 bars). To set pressure, pull the
adjusting knob up and either turn the knob clockwise (CW) to increase the pressure or counterclockwise
(CCW) to decrease the pressure.
