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.

| 1 Operational life is dependent on pressure, temperature, rotational speed and duty cycle. Maximum values do not apply concurrently. Please consult the factory for actual value. 2 Break-in torque may be higher. Flexible conduit should be used to couple to the rotating component. The torque arm must be loose coupled. |
