KB II Two-Quart Pressure Cups
DESCRIPTION
All KB-II style cups are pressure regulated
and have a 2.4 quart (77 oz.) capacity. They
are designed to be attached to any manual
spray gun with air and material hose. The
cup may be carried in one hand using the
comfortable hand grip or left on the floor
while spraying. The KB-II's wide diameter and
low profile provides a low center of gravity
which increases stability and resists tipping.
Models KB-555 and KB-545-SS include a 0-30
psi gauge. KB II cups are supplied with KK-
5051 disposable cup liners (5 each) to reduce
clean up time and cleaning solvent.
Pressure cups provide a greater degree of
control over atomization air and material
pressure than obtainable through use of
suction feed equipment. Pressure cups also
enable user to apply heavy or more viscous
materials in small amounts where a 2 quart
capacity is sufficient for the job.
INSTALLATION
Risk of injury. Cup is under pres-
sure. Disconnect cup assembly
from air supply before installing or
removing lid assembly from cup
for filling or cleaning.
