B38 - Stainless Steel, Precision Filter/Regulator
Installation & Maintenance Instructions
ASSEMBLY
1. Lubricate threads and nose of adjusting screw (2) at
regular intervals with suitable grease eg. Speerol APT2.
2. Lubricate seals (16, 36, 37) with light coat of good
quality grease.
3. Assemble the unit as shown on the exploded view.
4. Torque Table
Item Nm (Inch-Pounds)
4 (screws, stainless steel model) 7,3/3,3 (66/30)
CAUTION
Water vapor will pass through these units and could
condense into liquid form downstream as air temperature
drops. Install an air dryer if water condensation could have
a detrimental effect on the application.
WARNING
These products are intended for use in industrial
compressed air systems only. Do not use these products
where pressures and temperatures can exceed those listed
under Technical Data.
If outlet pressure in excess of the ilter/regulator pressure
setting could cause downstream equipment to rupture or
malfunction, install a pressure relief device downstream of
the ilter/regulator. The relief pressure and low capacity of
the relief device must satisfy system requirements.
The accuracy of the indication of pressure gauges can
change, both during shipment (despite care in packaging)
and during the service life. If a pressure gauge is to be used
with these products and if inaccurate indications may be
hazardous to personnel or property, the gauge should be
calibrated before initial installation and at regular intervals
during use. Before using these products with luids other
than air, for non industrial applications, or for life-support
systems consult Norgren.

• Only non-lammable gasese to be used as a medium.
• Surface temperature dependant on process luid
temperature and ambient temperature - must be
below the ignition temperature of the lammable gas
or dust.
• Earth unit and/or pipework to avoid electrostatic
discharge.
• Precautions should be taken to prevent hazard from
adiabatic compression.
• Use wet cloth for cleaning.
• Protect the unit from object falling onto it.
• Avoid contact with corrosive environment.
• For servicing the unit it is recommended to carry out
this work outside of the danger zone.
• For details of ignition hazard assessment contact
