I just got a Lakewood HV-18 with 2.4 amp Mcmillan motor from a neighbor and was wondering if anyone can tell me the CFM's for each of the fan's speeds.

I think you mean RPMs? CFMs isn't normally measured in terms of air movement on High speed, Medium speed and Low Speed, its usually measured as an overall measurement of what the fan is capable of moving air wise on the highest speed setting whereas RPMs are measured on all three speeds, and generally speaking most box fans (I'm assuming you are referring to a box fan in this post) range between 600 RPMs and 1500 RPMs.
Hope this helps.

No I'm not referring to a box fan and yes I am asking about CFM's. Several fans have CFM's listed at all speed levels.

Well then I don't know then because unless you have the fan's original box or an original advertisement for your particular fan, that kind of informations isn't really general knowledge on here, you might try searching through the archives on here to see if they might have an old advert for your fan on here, but the only  problem is that in order to access that archive you have to be a paying member, which currently as a guest you can't access the archives here.

honestly i dont know how you would have been able to get this information. During development i am sure it would be in the product creation reports, but i am not sure without a vintage selling ad that it would have been published. In the 50s-70s sears and other brands used CFMs as selling points and also Sones (Noise) etc, but after awhile i dont think people cared and they stopped. Fans became throwaways and not something you invested in.... as long as it made wind, thats all that was needed
