Product Description
The Minneapolis Blower Door™ Ring C is an optional flow ring accessory for Model 3 Minneapolis Blower Door fans. It is used when a building or test condition requires lower airflow measurement than the standard rings can provide, helping blower door technicians capture airflow in the 330 to 85 CFM range.
Ring C attaches inside Ring B using rotating fastener clips, making it a straightforward add-on for existing Minneapolis Blower Door setups. Made from thermoformed virgin ABS plastic, this ring is a practical accessory for energy auditors, HERS raters, weatherization crews, HVAC diagnostic contractors, and building performance professionals working on tighter homes, smaller zones, or lower-leakage envelope tests.
