AIR FILTER INSTRUCTION SHEET
PPR2-N02BG-2
Maximum Supply Pressure: 250 PSI
Maximum Operating Pressure: 30 PSI
Operating Temperature Range: 40⁰F to 140⁰F
Installation
***RECOMMENDED - INSTALL A PARTICULATE FILTER BEFORE THE REGULATOR***
Install regulator with the air flow as indicated by the arrow on the unit.
Install regulator as close as possible to the air operated equipment for best performance.
Locate the regulator upstream from the lubricator.
Mount with the knob up or down on regulator.
If the air line contains water, sludge or foreign materials, a filter should be installed on the upstream side to protect the regulator.
A tamper resistant feature is available to lock in specific air requirements.
After a regulator has been installed in the air line, the adjustment knob should be turned counterclockwise until compression is released
from the pressure control spring. This prevents over pressurizing the air operated equipment when the air supply is turned on.
Connect piping to proper ports using pipe thread sealant on male threads only. Do not allow sealant to enter interior of regulator.
Air line piping should be the same size as regulator ports.
Operation
Pull knob to adjust air pressure.
Turn clockwise to increase pressure.
Turn counterclockwise to decrease pressure.
Note: On non-relieving models only, reduce pressure to lower than estimated final operating pressure, purge air (open or actuate air
operated equipment to relieve pressure), adjust pressure upward as needed.
Push down to lock knob. Maintenance

WARNING
IMPROPER SELECTION OR IMPROPER USE OF PRODUCTS AND/OR SYSTEMS CAN CAUSE DEATH, PERSONAL INJURY, AND
PROPERTY DAMAGE. PNEUMATIC PLUS IS NOT LIABLE FOR USE OTHER THAN SPECIFIED.
To avoid unpredictable system behavior that cause personal injury and property damage,
User must be trained and equipped for the handling, use and servicing of high pressure fluids and systems.
Follow all applicable safety and maintenance procedures.
Obey local, government and agency codes and regulations.
Disconnect electrical supply if necessary before installation, servicing or conversion.
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.
These products are intended for use in industrial compressed air systems ONLY. Do not use on life support systems or breathing air systems. Never
use polycarbonate plastic bowls with air supplied by a compressor lubricated with synthetic oils or oils containing phosphate esters or chlorinated
hydrocarbons. They can carry over into the air distribution system and chemically attack and possibly rupture the bowl. On these applications use a
metal bowl. Also, do not expose the polycarbonate plastic bowl to materials such as trichloroethylene, acetone or paint thinner. Cleaning fluids or
other harmful materials will craze and/or rupture the bowl. If materials harmful to polycarbonate are present either outside or inside the bowl, use a
metal bowl.
