What is the CFM rating, size motor, whether sleeve or ball bearings?

Don't know the CFM, but these things have been running 24/7 at my local gym for at least the last four years. They are very robust -- industrial. Nothing like cheaper consumer fans.

I don't know cfm rating-not listed, sorry not near fan to check. Permanent lubed bearings I believe was in the literature.

I already installed it in my cooler, but I have the old motor still (which has almost identical dimensions). What dimensions do you need?

Thanks for your question! According to the manufacturer's website the CFM of this fan is 740 / 600. I hope this helps!

Cfm is an ambiguous rating and it's difficult to say. I would say 38 would be better as it accounts for compressed volume of air. However if you are using power tools or anything that needs more air I would look much higher or you will see significant pressure drops. Something in the 100's at least or 200's would be ideal. I bought this and switched to a 200+ scfm and I only get a drop of 2-3psi. With this unit I experienced 20-30psi drop at full load.

The bearings are ABEC 7; they were terrible in the first batch, but the newer boards come with some pretty good ones - don't be afraid to try breaking the board in before deciding to order a different set of bearings!

As I understand it, it depends on how you plan to mount the fans. If mounted vertically, the sleeve bearings are fine, but if you mount horizontally, the ball bearings are better. Horizontally mounted sleeve bearing fan will wear out faster and be noisier. Ball bearings are round, sleeve bearings are cylindrical. Ball bearing fans are more expensive, but in the long run worth the extra.

CFM need is 6.1, Most 1/2 inch impacts require around 5-7 CFM. You might need to go with a 3/8 drive for lower CFM.

try getting Robinson Racing 1050 48p Six Pack Pinion 16/26t and experiment to see what speed set-up works best.

Big. Its not universal. Haha.. I took the fan apart and used the motor int he stock fan on my ATV and with some lock tight and screws it works fine in the original housing my ATVs fan had. Way too big to fit on my grizzly 300 though.

Not sure, but the bearings in mine went out 5 minutes after I installed it... noisier now than the noisy one I replaced.

It is listed by Fasco as a direct replacement. That means it should fit and work with little to no adaption needed but it does not mean it is the same. The biggest difference you will see is one having sleeve bearings versus ball bearings. Also, any parts that would be needed to make it work are included by FASCO in the package. I replaced my unit with last year with this unit. It took around 30 minutes. Good Luck.

I believe the 600 cfm will be ideal for a stock 400" or a slightly warmed up engine. I have had no experience withChevrolet engines but I believe that is the carburetor you want to use.

what do you mean by size? You need to pull the motor and look at the HP and serial no.s. and brand. I believe thats all I matched up.

What Darren said is spot on. It should be fine. 75 RPM is only 7.5% (0.075) faster than the one you have now. If you still want another opinion, I would drop by the local technical college/school and find the HVAC instructor. Ask him or her to make sure. And it would be free advice, too.

I wondered the same thing. After checking out some other reviewers I think the ball bearing units overall were in better quality I think. Also someone mentioned something about sleeve bearings being mounted a certain way that would cause early failure or something of that nature. Either way i don't think it was a huge price difference extra for ball bearings. I'd get these again. They are good.

Robert, I would be happy to answer your question for you and also let you know with a phone call 360-755-0665 you can save some money.Most customers use the Minn Kota Endura 30lb thrust motor. this is sufficient for most applications. The 50lb would give you that little extra in case you got caught in a heavy wind.Ron SchmidtValley Sports and More360-755-0665
