The fans formally known as Dayton Marleys.

I've been doing some research on this topic as of late. We recently discovered they made a 72" version (I'd seen 72" stamped fans, but not cast), so I called Marley to see if anyone there knew anything about it. The oldest guy in the office at the time wasnt around when the 72" version was made, but he was there when Marley bought Leading Edge. Apparently all of the fan designs, including the contract with Grainger for Dayton, came from Leading Edge. Prior to the buyout in the mid 1990s, Marley had nothing to do with these fans. It seems unlikely that Leading Edge was the OEM.

I cracked open several of the fans I have.

60" labeled Leading Edge. Capacitor made in AUSTRALIA, labeled 1975. Fan serial number includes '1985'.
56" labeled Leading Edge, purchased and installed at the same time as the 60". Capacitor made in Hong Kong, no date. Fan serial number includes '1985'.
48" labeled Sonnet-Air, but under the yoke it says "Weatherite Industries LTD, Hong Kong". Capacitor made in AUSTRALIA dated 1975. No other date markings.
38" labeled Emerson. Dated 1980. No other markings.

We've seen a Westinghouse labeled fan in the US from 1976.
In Australia, we've seen fans labeled Weatherite, Weatherite licensed by Westinghouse, North Sydney Manufacturing Co, and China Cold Storage & Engineering Co Ltd.

So . . . is Weatherite the OEM? Based on some of the fans in Australia, it doesnt seem likely, but then why do I have a US fan relabeled, with a HIDDEN label "Weatherite, Hong Kong"?

"China Cold Storage & Engineering Co Ltd" appears to be a Chinese HVAC company. Maybe they made fans in the 1970s, but seems unlikely.

"North Sydney Manufacturing Co" sounds like a good candidate for the Aussie relabel, but then why are they all labeled Weatherite? And Westinghouse, which is a US company?

The fact that some of the capacitors in the US fans CAME from Australia may also be a clue.

Here is a picture of a Westinghouse labeled fan in the US in 1976.


Here's a very early Australian fan:

Here is a 56" Leading Edge motor and a 48" Sonnet Air motor:


Here is a 60" Leading Edge motor and a 56" Leading Edge motor:


And the blades:


Here are the labels on two Australian fans:

Do you have any pictures of the 72 inch versions? I've never seen or heard of a 72 inch industrial.

Either way, interesting information. The conflicting dates of manufacture in 1985 with the capacitor from 1975 is very odd, I would think that's too far apart for them to have used them as old stock in their fans, but I suppose it is possible.

Maybe Weatheright was originally a make under Westinghouse, then either got bought out or separated from Westinghouse into its own company?

We have no pictures of the 72" fans.

Given the size increase from 56" to 60", which is only 4 inches, is pretty big, another 12" increase must be huge!
