Measuring air flow of residential forced air registers can be a challenge. The uneven pattern of air flow from typical residential registers and the relatively low register flow rates make accurate measurement difficult with traditional flow capture devices.
The Energy Conservatory has developed the FlowBlaster Capture Hood Accessory for the Duct Blaster® to convert it to a powered flow hood to accurately measure air flow in all residential applications.
The FlowBlaster is designed to measure supply, return and exhaust flow from 10 to 300 CFM. The FlowBlaster works by adding necessary flow conditioning and then precisely adjusting the speed of the Duct Blaster® Fan to compensate for the pressure loss through the conditioners.
The unique, patent-pending design compensates for variations of construction and is able to measure air flow more accurately than commercial capture hood devices that have been used in the residential market.
The FlowBlaster works with your existing Duct Blaster Fan and DG-700 Pressure and Flow Gauge. The fan is powered by a new combination fan speed controller and rechargeable Lithium-Ion battery.
Set the DG-700 to Cruise, place the FlowBlaster to the grill and the fan will automatically adjust to read the correct value. Your airflow measurement is complete in just seconds. Accurate, quick readings with the reliability you expect from The Energy Conservatory. The FlowBlaster includes everything you need to turn your Duct Blaster® into a powered capture hood.
