How to read a 3000H nameplate

Hudson fans carry an adjustable pitch code on the nameplate. APT 14H 6 2 7/8" BORE breaks down like this:

• APT: adjustable pitch fan.
• The number: fan diameter in feet.
• H: the blade, here Tuf-Lite II. H is Tuf-Lite II, K is Tuf-Lite III, KW is Tuf-Lite III wide chord and M is Tuf-Lite IV.
• The next number: blade count.
• The bore: shaft size, where it's given. Large fans are often ordered without it.

Match the bore to a bushing: Q-2 fits 1" to 2.62", R-2 fits 2.68" to 3.62", S-2 fits 3.68" to 4.19" and U-1 fits 4.25" to 5.50". Read those off the nameplate and get in touch. We'll match the parts.

Obsolete H blades and the K blade upgrade

Tuf-Lite II was introduced in 1984. It is now only sold new in 34, 36 and 40 ft, and Hudson moves replacement projects to Tuf-Lite III. For a 3000H fan that means K blades.

Hudson says K blades can replace H blades on the original 23 inch hub with 4 to 9 blades, as long as every blade on the fan is changed at the same time. Tell us the diameter, blade count and bore and we'll confirm the change for your fan. Russell De Jesus, P.Eng, reviews the re-rate where one is needed.
