IMPORTANT: Read and follow all Instructions and Safety

Precautions before installing, operating or maintaining this

equipment. Keep this manual for future reference.

Improper use can cause bodily injury or equipment

damage. Read the following:

• This air regulator and gauge assembly is intended only

for use in general service air systems. Do not use for

liquids or gases other than air.

• Do not use where pressure or temperature can exceed

rated operating conditions (see speciﬁcations).

• Regulated outlet pressure must never be set higher

than the maximum operating pressure of the down-

stream air tool or equipment. An outlet pressure gauge

should always be used.

The accuracy of the indication of pressure gauges can

change during shipment and normal use. If gauge

accuracy is necessary for preventing risks of injury or

property damage, the gauge should be checked before

use and on a routine periodic basis. (See ANSI B40-1974

for gauge standards.)

DESCRIPTION

This unit is used in a compressed air system to maintain a nearly

constant outlet pressure despite change in inlet air pressure and

changes in downstream ﬂow requirements. It is also used for

ﬁner control of air at the spray device. The air setting can be

locked in place by pushing the adjusting knob downward.

The DeVilbiss HARG-510 Air Regulator and Gauge Assembly is a device designed for use in compressed air systems to maintain a nearly constant outlet pressure despite changes in inlet air pressure and downstream flow requirements. It also provides finer control of air at the spray device. The air setting can be locked in place by pushing the adjusting knob downward.

Important Safety and Usage Information:

This assembly is intended only for general service air systems; it should not be used for liquids or gases other than air.
Do not use where pressure or temperature can exceed rated operating conditions.
The regulated outlet pressure must never be set higher than the maximum operating pressure of the downstream air tool or equipment. An outlet pressure gauge should always be used.
The accuracy of pressure gauges can change during shipment and normal use. If accuracy is critical for preventing injury or property damage, the gauge should be checked before use and on a routine periodic basis (refer to ANSI B40-1974 for gauge standards).
Do not submerge the regulator in spray gun solvents or use solvents to clean regulator parts, as this can damage the gauge or regulator components.
Risk of injury from pressurized components: Always turn off inlet air pressure and bleed off remaining pressure before disassembly.

Technical Specifications:

Type: Diaphragm, relieving
Inlet Size (Nipple): 1/4" NPS(M)
Outlet Size (Swivel Adapter): 1/4" NPS(F)
Gauge Port Size (two) in Regulator: 1/8" NPT(F)
Gauge Range: 0-160 PSIG
Maximum Air Flow Rate: 15 SCFM
Rated Operating Conditions:
- Inlet Pressure: 300 PSIG max.
- Temperature: 0° to 150° F with dewpoint less than air temperature below 35° F
Outlet Pressure Adjustment Range: 5 to 100 PSIG. While the regulator can be adjusted to zero PSIG and to pressures higher than 100 PSIG, it should not be used to control pressures outside this specified range.

Construction Materials:

Bonnet and Valve Seat: Acetal
Diaphragm: PTFE/Buna-N/PTFE
Body: Zinc
Valve: PTFE

Installation:

Install the regulator as close as possible to the device being serviced. It can be installed at any angle.
In systems with a cyclic demand, install the regulator upstream of cycling control valves.
Air line piping should be the same size as the regulator ports.
Air flow must be in the same direction as the arrow on the bottom of the regulator body.

Operation:

Before turning on system air pressure, turn the adjusting knob full counterclockwise. This closes the regulator to produce zero air pressure. The knob locks in position when pushed downward towards the regulator body.
Turn on system air pressure.
Turn the regulator adjusting knob clockwise until the desired outlet pressure is reached.
To avoid minor readjustment after making a change in pressure setting, always approach the desired pressure from a lower pressure. When reducing from a higher to a lower setting, first reduce to some pressure less than that desired, then bring up to the desired point. Lock the pressure setting by pushing the knob downward.

Preventative Maintenance and Cleaning:

Clean parts using warm water and soap.
Inspect all parts and replace any damaged ones.

Disassembly for Maintenance:

Turn the regulator knob counterclockwise until it stops.
Unscrew the bonnet from the regulator body.
Remove the adjusting screw and nut, then the regulating spring (4), slip ring (5), and diaphragm (6).
Using a screwdriver, unscrew the valve seat (7) and o-ring (8).
Remove the valve (9) and valve spring (10).

Reassembly:

Apply a small amount of lubricant SSL-10 gun lube to the adjusting screw threads inside the bonnet.
Torque the valve seat (7) to 4-6 in./lbs. (do not overtighten).
Torque the bonnet to 50-60 in./lbs.
