Old topic, new inquiry... Replacing the original AC squirrel cage blower

[rwaldrop13]

Good afternoon! Looking for some advice/experience. I pulled the original blower from the forward V-berth cabin in my Hat 54' to try to identify a replacement. Not only is the electic motor seized, the squirrel cage is rusted out as well. I followed some links from an older thread with a similar topic, but could not get a match based on the model number. I've reached out to Electric Motor Warehouse, and another vendor to see if the blower they listed on their website is a direct replacement. I'm trying to replace a Dayton Model 8C264, which is apparently a defunct model number. I've attached a couple of pictures of the data plate - Anyone else run into this? The existing AC system definitely performs - Even in Florida.20201014_134430.jpg20201014_134346.jpg

I looked up Daytona electric motors and found numerous available. I typed in your model number but it did not come up. You might try to contact them on Monday and see if they have a crossover for you.

Grainger sells Dayton. Did you check with them?

115V or 230V? This is 230V if you could use it.

Following other thread answers on this website, I contacted Electric Motor Warehouse, provided all the information I could, and asked about a Dayton blower they showed on their website asking if it was a direct replacement or if they could steer me in the right direction. The answer I got back? "That's a Dayton part or model number contact them." So obviously they don't want my business. I've contacted Grainger - Not optimistic, not only are they not good with customer service but they are ridiculously high-priced. That's an opinion based on a LOT of experience with them thru different employers as a fleet manager, service manager, etc.

Thanks Robert - I am looking for a 230V, not sure if that one will fit but going to look at the pictures more closely.

Solved. Grainger is the parent company of Dayton, but apparently the Crusair products used exclusive model/part numbers that did NOT cross over. However, I printed a spec sheet off Grainger that I thought was a close match to the existing blower, and measured the physical dimensions and matched up the electrical specs from the data plate. WIN! Blower has been ordered. $130.00

Yes, Dayton is a Grainger brand. Glad you found a match.

So for anyone else struggling with this issue, I found out that the current model of this blower is the Dayton Model 1TDR4 Blower 271 CFM 1670 RPM 230V 60/50hz.

After I printed out the spec sheet, and compared data plates and measured physical dimensions, I am convinced that this is the same blower with an updated number. Bonus - It not only is a complete drop-in including the squirrel cage, it has 7-inch leads instead of the motor it replaced which had NO power leads.

Here's why I shouldn't have bothered. A month after replacing the blower, the compressor locked up. However, I have completed the install of a new MarineAir unit with connections to the original ducts feeding the galley and V-berth. Easier in some ways than expected, and a good trial run for the eventual installation of a second similar unit to service the aft and midship staterooms.
