Minneapolis DuctBlaster® Flow Ring 4
Ring 4 is an optional flow ring accessory to the Duct Blaster®fan used to measure 25 – 2.4 CFM with a minimum fan pressure of 5 Pascals.
Flow rates can be displayed using various TEC software or app programs. Flow rates can also be manually determined by measuring the fan pressure signal from Ring 4 and using the flow table under the tab - Documents - Ring 4 Quick Guide or in Appendix F of the Minneapolis DuctBlaster® User Guide.
The flow ring temporarily attaches to the fan housing with a 40 inch piece of trim (item DBTRIM sold separately).
