Filter / Regulator
Installation
1. The Filter / Regulator should be installed with reasonable accessibility for
service whenever possible – repair service kits are available. Keep pipe or
tubing lengths to a minimum with inside clean and free of dirt and chips.
Pipe joint compound should be used sparingly and applied only to the male
pipe – never into the female port. Do not use PTFE tape to seal pipe joints
– pieces have a tendency to break off and lodge inside the unit, possibly
causing malfunction. Also, new pipe or hose should be installed between
the Filter / Regulator and equipment being protected.
2. The upstream pipe work must be clear of accumulated dirt and liquids.
3. Select a Filter / Regulator location as close as possible to the equipment
being protected.
4. Install Filter / Regulator so that air flows in the direction of arrow on body.
5. Install Filter / Regulator vertically with the bowl drain mechanism at the
bottom. Free moisture will thus drain into the sump (“quiet zone”) at the
bottom of the bowl.
6. Gauge ports are located on both sides of the Filter / Regulator body for your
convenience. It is necessary to install a gauge or socket pipe plugs into each
port during installation.
Operation
1. Both free moisture and solids are removed automatically by the filter.
2. Manual drain filters must be drained regularly before the separated moisture
and oil reaches the bottom of the baffle or end cap.
3. The filter element should be removed and replaced when pressure
differential across the filter is 69 kPa (10 PSIG).
4. Before turning on the air supply:
4A. On SB1, disengage the adjusting knob by pulling upward. Turn adjusting
knob counterclockwise until the compression is released from the pressure
control spring.
4B. On SB2, push down on the adjusting knob while turning knob
counterclockwise until the compression is released from the pressure control
spring. (Knob is locked when up.)
5. Then turn knob clockwise and adjust regulator to desired downstream
pressure. This permits pressure to build up slowly in the downstream line.
6. To decrease regulated pressure settings, always reset from a pressure lower
than the final setting required. Example, lowering the secondary pressure
from 550 to 410 kPa (80 to 60 PSIG) is best accomplished by dropping the
secondary pressure to 350 kPa (50 PSIG), then adjusting upward to 410
kPa (60 PSIG).
7. When desired secondary pressure settings have been reached, push the
knob down to lock this pressure setting on the SB1 or up to lock on the
SB2.

• Disconnect air supply and depressurize all air lines connected to this
product before installation, servicing, or conversion.
• Operate within the manufacturer’s specified pressure, temperature,
and other conditions listed in these instructions.
• Medium must be moisture-free if ambient temperature is below
freezing.
• Service according to procedures listed in these instructions.
• Installation, service, and conversion of these products must be
performed by knowledgeable personnel who understand how
pneumatic products are to be applied.
• After installation, servicing, or conversion, air and electrical supplies
(when necessary) should be connected and the product tested for
proper function and leakage. If audible leakage is present, or the
product does not operate properly, do not put into use.
• Warnings and specifications on the product should not be covered by
paint, etc. If masking is not possible, contact your local representative
