How to read a 3000K nameplate

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

• APT: adjustable pitch fan.
• The number: fan diameter in feet.
• K: the blade, here Tuf-Lite III. 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.

Specifications and part numbers from Hudson's published 3000K installation manual, put in our own words. Common parts for every series, including clamp bolts, hub spools and seal discs, are on the Hudson parts page. Every number is also in the part number lookup.
