Default Cooling fan cfm

Does any one know the cfm of our cooling fans at high speed?

I think I have found a good alternative but need to check the cfm is something close to ours.

I found one figure that may put you in the ball park. The archives have a comment by Jules regarding the Kenlowe system he offered as a replacement fan.

We've always used the Kenlowe 17 inch which is rated at 265 Watts but due to their more efficient blade is only 10% behind in Litres per minute Airflow IIRC.
Performance even against high resistances - 3750m³/h @ 3.75mm wg
Advanced forward curved blades
Two speeds low amp and high amp (18/24A)


So according to this, you're looking at 3,500 to 4,000 cubic metres per hour. A bit of maths will give you the cfm figure.


EDIT: Here's the Kenlowe specs (the 17" model is at lower rhs). https://www.kenlowe.com/CoolingOEM.php
The later Revotec/Comex system is also about 3,800 cubic metres/hr.

Thanks Tcut, that is great.

I will get one of these alternatives ordered and see how it works.
