● Compact design

● Full flow gauge ports

● Low torque, non-rising adjusting knob

● Snap action knob locks pressure setting when

pushed in

● Standard relieving models allow reduction of outlet

pressure even when the system is dead-ended

● Protects air operated devices by removing liquid and

solids contaminants

● Screw-on bowl reduces maintenance time

● Can be disassembled without the use of tools or

removal from the air line

GENERAL PURPOSE FILTER/REGULATOR

1.1 GENERAL OVERVIEW

Filter/regulators combine the features of a filter and
regulator with a single compact body.

Air passes through the filter section first
removing water and particle contaminants, and is
then regulated by the top regulator section.

See individual filter and regulator sections
for details.

1.2 PERFORMANCE

CHARACTERISTICS

The regulator section of the filter/regulator
determines the flow and regulation characteristics of
the unit.

Flow is therefore measured in terms of
pressure droop from set pressure (see regulators)
and not flow versus pressure drop as in a filter.

Regulation characteristics are determined
in the same way as regulators.

1.3 SPECIALS

1.3.1 Can we do a Coalescing Filter/Regulator?

Yes. We have a B39 unit in the 07 Series. Other
sizes could be considered for volume customers.

1.3.2 Can we do special materials?

Units are available in stainless steel (B05 and B38)
for harsh environments and process applications.
