The FlowBlaster™ Capture Hood Accessory is designed for use with the company's Minneapolis Duct Blaster® System. The product is designed to accurately measure airflow in residential heating-cooling registers with flows from 10 to 300 cfm. The FlowBlaster™ accessory conditions the flow. It then compensates for pressure loss of the flow conditioners and variations in construction by precisely adjusting the Duct Blaster® fan speed to remove the pressure loss. The interactive, patent-pending design adjusts the fan air speed measurement to zero to produce accurate measurements of register flow. The accessory requires the use of a Duct Blaster fan, flow rings and a DG-700 digital pressure and flow gauge. The complete FlowBlaster™ kit includes a carrying case, housing, 16- by 16-inch hood assembly, Duct Blaster fan handles; battery-powered controller, holster, and battery charger; coiled cord for power and communication; plastic tubing and fan connect trim; and manual.
