Miniature Regulator/Filter/Gauge
Description
Model 7936 is a combination regulator, moisture separator
with filter, and a gauge. This model has a drain feature that
allows bowl sediment and condensate to be automatically
discharged.
Regulator
The regulator is self-relieving. Anytime the regulated air
pressure is lowered, air exhausts at a relief port located in the
spring cage. See Figure 2.
Filter
The filter removes impurities from the airstream in two ways.
A deflector valve plate removes heavy particles (greater than
20 microns) dynamically by centrifugal force. The removal of
smaller particles occur statically through the filter element.

WARNING
Release all pressure within the system prior to
performing any maintenance procedure.
• Close the air line shut-off valve.
• Turn the adjusting knob on the regulator fully
counterclockwise.

Operation and Cleaning
Caution: Do not exceed 150 psi (10.3 Bars) line pressure. Do not use on systems lubricated with synthetic oils, oils
with phosphate esters, or chlorinated hydrocarbons. Do not clean the bowl with chemicals (use soap and water only).
These oils, chemicals, or excessive pressure will weaken the structure of the bowl and may cause it to rupture.
