Model 801

COOLANT FLUID ROTARY UNION (FRU)

The Model 801 Fluid Rotary Union (FRU) is designed to operate with ethylene glycols (non-silicate inhibitors), propylene glycols and polyalphaolefins (PAO), providing very low leakage rates over relatively long service intervals. The Model 801 FRU can be used as a standalone unit, or can be integrated with electrical slip rings and / or fiber optic rotary joints.
