The wheel shall be balanced statically and dynamically as per ANSI/AMCA Standard 204.96 Balance Quality & Vibration Levels for Fans to grade G 6.3.
• Shafts will be 316ss accurately turned & gauged for accuracy and sized so that the first critical speed is a minimum of 1.35 times the maximum operating speed.
• Shaft Seal shall be Teflon precision cut for a close tolerance fit with the fan shaft, encased within an FRP seal box with encapsulated 316ss fasteners.
• Bearings shall be pillow block design sized to have a minimum life of 50,000 hours based on AFMBA L₁₀ standard. Bearings shall be equipped with extended lubrication lines with grease fittings on the outside of the fan housing.
• All fasteners to be 316 stainless steel construction.
• The exterior of the fan shall have a grey gel coat finish containing U.V. inhibitor to prevent ultra violet light degradation.

Note: The addition of UFBL Features to the standard fan will amend the specification accordingly
