Which Fans This Motor Fits

Fan Series Size Assembly Code
ACED 150 150C13D
ACED 150 150C15D

Both assemblies take the same motor. A size 150 built as a 10D runs slower and takes a different part, so read the whole code and not just the size.

If the code is worn off, the Loren Cook serial number lookup will work it back from the serial number.

Genuine OEM Parts for Size 150 Exhaust Fans

Replacement parts are available across the size 150 lineup, including motors, wheels, shafts, bearings and top cap assemblies. Larger direct drive units in the same family take the 100170 motor at the 120 and 135 sizes, so confirm the size before ordering either one.

Heinlein is an authorized Loren Cook distributor, so parts stay available for these fans after a unit leaves production, and a single part or a whole replacement fan can be sourced. If what you need is not listed on the site, call us and we will find it.

Frequently Asked Questions

What is the difference between the 105105 and the 105104?

Speed and fan size. Both are 3/4 HP at 115 volts. The 105105 runs 1550/1300 RPM and goes in size 150 units built as 13D or 15D. The 105104 runs 1050 RPM and goes in the 180C10D. Same horsepower, different fan.

Will this motor fit a 150C10D?

No. The 150C10D is a slower assembly and takes the 100172 motor at 1/3 HP and 1075 RPM. The 105105 is built for the 13D and 15D assemblies in that size.
