Product Description
The Duct Blaster® Fan with Rings and Fan Speed Controller is a replacement or partial-system assembly for Minneapolis Duct Blaster users who need the fan, flow rings, and controller without purchasing a full Duct Blaster kit. It includes a new Series B Duct Blaster fan assembled with a fan speed controller, calibrated Flow Rings 1, 2, and 3, a black fabric fan cover, a 40" black fan trim piece, and a white foam foot for supporting the fan during testing.
This assembly is useful for duct leakage testing professionals, energy auditors, weatherization teams, HVAC diagnostic contractors, and building performance technicians who already have the rest of the Duct Blaster setup, such as gauges, transition plates, tubing, or flex duct. With the included calibrated rings, the fan can measure approximately 10 CFM to 1500 CFM and can create up to 50 Pascals of back pressure, making it suitable for common residential and light commercial duct leakage diagnostics.
