How to read a 5000M nameplate
Hudson fans carry an adjustable pitch code on the nameplate. APT 28M 8 breaks down like this:
- APT: adjustable pitch fan.
- The number: fan diameter in feet.
- M: the blade, here Tuf-Lite IV. 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 5000M 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.
Before you order.
Do the 5000M and 5000K share hub parts?
For 9 to 12 blades, yes: Hudson lists the same hub assembly and hub part numbers for both. The 6 to 8 blade 5000M hubs have their own numbers.
What torque do the 5000M blade clamp bolts take?
It depends on the bolt. 316 stainless bolts take 130 ft-lb lubricated. Grade 8 galvanized bolts take 250 ft-lb lubricated or 280 ft-lb dry.
Which seal disc fits a 5000M fan?
The 64" D5937 on fans with 6 to 8 blades, and the 76" D5938 kit on 9 to 12 blades.
