Graco 308024d is an air-assisted airless high-efficiency low-pressure system that provides precision regulation of air pressure for optimal performance in various applications. It is designed to comply with SCAQMD Air Quality Rules 1124, 1136, and 1151, ensuring compliance with environmental regulations. With a maximum inlet pressure of 500 psi (34 bar) and a reduced range of 0-10 psi (0-0.7 bar), the regulator ensures precise control of air pressure.

The regulator features Buna-N on Dacron diaphragms, providing durability and resistance to wear. It is equipped with a 1/4 NPT inlet and outlet, allowing for easy integration into existing air lines.

INSTALLATION
Preparing to Install the Air Regulator
Clean the air lines to remove dirt and scale before install-
ing the air regulator.
Apply a minimum amount of pipe compound to the air line
male threads.
CAUTION
To avoid getting compound into the air regulator
and damaging it, start with the third thread back
and work away from the end of the air line when
applying pipe compound.
CAUTION
To avoid contaminating the air supply to the air reg-
ulator, do not use an automatic air line lubricator;
lubricate the motor manually, instead.
Installing the Air Regulator
CAUTION
ALWAYS use an air line filter to remove harmful
dirt and moisture from your compressed air sup-
ply. Dirt and moisture will affect air regulator per-
formance.
Install the air regulator in the air line. It can be mounted in
any position without affecting its operation.
The regulator has a 1/4 npt inlet and outlet, which are
labeled with arrows indicating the direction of flow. Tight-
en the inlet and outlet connections securely.
CAUTION
DO NOT use undersized fittings as they will limit
flow through the regulator and cause the pressure
to drop downstream.
ADJUSTMENT
Turn the knob clockwise to increase the regulated air
pressure. Turn it counterclockwise to decrease the regu-
lated air pressure. The locknut is fixed to ensure the out-
let pressure does not exceed 10 psi (0.7 bar).
NOTE: If the regulator is difficult to adjust, make sure the
seal ring is lubricated.

MAINTENANCE
WARNING
To reduce the risk of serious bodily injury, including
splashing in the eyes or on the skin, or injury from
moving parts, ALWAYS shut off the air supply and
relieve all air and fluid pressure in the system be-
fore removing or servicing the air regulator.
The regulator does not have to be removed from the air
line to clean it. Remove the two No. 10–32 screws on the
bottom of the regulator, then pull out the inner valve
assembly.
Wash the inner valve assembly with solvent. Be careful
not to damage the diaphragm and valve facings.
CAUTION
Do not use acetone, carbon tetrachloride, trichlo-
rethylene or similar solvents to clean the regula-
tor. These solvents could damage regulator
parts.
Be sure the spring housing vent hole is not clogged. Keep
the vent hole clear as a slight flow of air through this hole
is necessary for the regulator to operate properly.
Lubricate the adjusting screw with petroleum jelly.
