WorldWide List

Update 8-17-18 QuietCool is now 4th in the order of highest performance because the company has just complied with the state of California by displaying the true HVI-916 air flow like the other companies do now. But QC still insists on showing a misleading higher CFM value – here is an example from their web site:

Name STL PRO-7.0X Airflow* Hi:6996 CFM HVI-916 Airflow (CA Title 24)** 5200 CFM
The star is “*Listed airflow specs are tested via a device that is calibrated to NIST standards.” which is meaningless because NIST does not have a standard for testing like the HVI-916 has.
So the list below had QC in 2nd place but now shows them 4th.

List shows highest air flow offered.

Thorwaldson   6320 CFM
VentCool          6123 CFM
