INTRODUCTION

The Graymills Air-Powered Ink and Coating Mixers were

developed to use with our on-press peristaltic and diaphragm

pumps, providing the level of in-tank agitation traditionally

supplied by centrifugal pumps. By continuously blending

the pigments, solvents, and additives, your viscosity and

print quality remain more stable, making your process more

predictable. Variable speed adjustment of the mixer allows you

to adjust to the needs of your inking system, while conserving

compressed air and avoiding any risk of foaming.

UNPACKING

Remove mixer from carton. The carton should contain the air

motor mounted on a shaft, 1 mounting plate, 1 propeller,

mufﬂer and air speed valve. Mixer is assembled except for

mounting hardware.

Unpack and inspect carefully. Contact shipper or Graymills if

you suspect damage or missing parts. Follow instructions and

put into use.
