Loren Cook Company Fan CVR

Warning: Only use compatible grease such as Exxon Mobil Polyrex EM and Chevron SRI.

Motor bearings lubricated properly?

Note: Reduce the intervals to half for vertical shaft installations.

Establish a schedule for inspecting all parts of the fan.

The frequency of inspection depends on the operating conditions and location of the fan.

Clean the propeller and air inlets if material build-up is excessive. Excessive build-up can cause imbalance and failure of the propeller.

Regular inspections are recommended for fans exhausting non-contaminated air.

All belt driven Propeller Wall fans with motors up to and including 5 HP are equipped with variable pitch pulleys. To change the fan speed, perform the following:

1. Loosen setscrew on driver (motor) pulley and remove key, if equipped.

2. Open or close the groove facing to change the pitch diameter.

Warning: This procedure requires trained personnel with PPE!

Conditions: RPM - 1000 to 3000, Temperature - -30 to 120 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.

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.

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.

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?

Warning: This procedure requires trained personnel with PPE!

Conditions: RPM - Up to 1000, Temperature - -30 to 120 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.
