(AV) hubs feature Timken tapered roller bearings and synthetic lubricants. All components are
suitable for high and low temperature operation and are interchangeable (except hub bodies) in 4, 5, or 6 blade configu-
rations. Hudson AV hubs are durable and designed for low maintenance and energy saving operation.

(white, prev. blue) fan blades are made from fiberglass reinforced vinyl-ester resin having a very
high strength-to-weight ratio and superior ultra-violet and corrosion resistance. An elastomeric blade/holder joint cover
(not shown) prevents moisture from entering blade.
The individually balanced blades can be replaced independently—matched sets are not required.
