GRACO 25T862 – Radial Piston Air Motor Retrofit Kit for Back-Geared Agitators

GRACO 25T862 – Radial Piston Air Motor Retrofit Kit for Back-Geared Agitators

Retrofit Kit 25T862 is a drop-in replacement that provides a 6:1 gear reduction for the gearbox and air motor. Use Kit 25T862 on non-geared agitator models that have a 24:1 gear reduction, in operation with high-viscosity materials.

By upgrading back-geared agitators with radial piston air motors, factory paint mix rooms can cut compressed air costs by up to 85 percent.
