How often should I lubricate my ACCUREX XID or XIB fan bearings?

[ChaseLee]

To maintain your ACCUREX XID Direct Drive or XIB Belt Drive Centrifugal Inline Fan's peak performance, proper bearing lubrication is crucial. The relubrication frequency hinges on operational intensity and environmental factors. Here's a guideline:

• 1 to 3 months: For fans in demanding conditions such as dusty or dirty areas, high temperatures, moisture-rich air, or environments prone to vibration.
• 3 to 6 months: For units running 12 to 24 hours daily under heavy loads or in moist conditions.
• 6 to 12 months: For fans operating 8 to 16 hours a day in a clean, relatively dry setting.
• 12 to 18 months: For infrequently used fans or those in light-duty applications within a clean environment.

Always use a high-quality lithium-based grease with an NLGI Grade 2 consistency. Some recommended options include Chevron SRI Grease 2, Mobilux EP 2, or Shell Gadus S2 V220 2, among others listed in the ACCUREX fan manual. Lubricate while the unit is running, and avoid overfilling or contamination.
