Can anyone recommend a good cab exhaust fan that's quiet and still has good airflow? Ideally has at least two speeds with low around 200-250 cfm and high 400-500 cfm. Quiet is important.
Those rather large Nylube ones are pretty quiet relative to the computer-fan style ones a lot of vendors are putting out these days. I think because the fan is so large it has no trouble with the CFM at a lower RPM than others.
