Loren Cook Company Fan CVR-S

Warning: This procedure requires trained personnel with PPE!

Select the condition of the fan

If not prelubricated, user takes responsibility for flushing bearings and lines, and maintaining a lubricant that is compatible with the installation

Select the type of lubricant used

For moist or otherwise contaminated installations; divide the interval by a factor of three. For vertical shaft installations divide the interval by a factor of two

Lubricate the bearing while the fan is in operation

Pump grease in slowly until a slight bead forms around the bearing seals

Warning: Excessive grease can damage seal and reduce life through excess contamination and/or loss of lubricant

Warning: This procedure requires trained personnel with PPE!

An NLGI #2 grease is a light viscosity, low-torque, rustinhibiting lubricant that is water resistant. Its temperature range is from -30°F to 200°F and capable of intermittent highs of 250°F.

Is the installation moist or otherwise contaminated?

Is the shaft installation vertical?

Was the bearing lubricated while the fan was in operation?

Motors are provided with a polyurea mineral oil NGLI #2 grease. All additions to the motor bearings are to be with a compatible grease such as Exxon Mobil Polyrex EM and Chevron SRI.

The above intervals should be reduced to half for vertical shaft installations.

Nema Frame Size - Up to and Including 184T

Warning: This procedure requires trained personnel with PPE!

Conditions: RPM - Up to 1000, Temperature - 120 to 200 F

Fan Bearings: The fan bearings are provided prelubricated. Any specialized lubrication instructions on fan labels supersedes information provided herein.

Bearing grease is a petroleum lubricant in a lithium base conforming to an NLGI #2 consistency.

If user desires to utilize another type of lubricant, they take responsibility for flushing bearings and lines, and maintaining a lubricant that is compatible with the installation.

For best results, lubricate the bearing while the fan is in operation. Pump grease in slowly until a slight bead forms around the bearing seals. Excessive grease can damage seal and reduce life through excess contamination and/or loss of lubricant.

In the event that the bearing cannot be seen, use no more than three injections with a hand operated grease gun.
