REGULATOR OPERATION
OPERATION
Binks models 85-448, 85-449 and 85-450 regulators
are flow-thru regulators offering virtually no
restriction for spray painting applications.
Efficient, low flow, regulated parts allow for easy
control of cup (fluid) pressure and/or rotary agitator
speed.
The following conditions must be observed:
1. Do not exceed 100 PSI inlet pressure.
2. When reducing the regulator setting, it is
necessary to relieve fluid supply cup of its
previously set pressure.
WARNING
Risk of injury from pressurized components. Turn off inlet
air pressure and bleed off remaining pressure before dis-
assembly.
!
CAUTION
Do not immerse this regulator in solvent or allow solvents
to enter any of the regulator openings. When using a gun
cleaning cabinet, remove the regulator before cleaning
the gun.
