The Series SAH SMART Air Hood® Balancing Instrument is the most accurate and easy to operate air flow hood on the market. By using the included hood stand and wireless communications to the handheld, a single operator can balance a branch in less time than traditional balancing teams. Besides being lighter than most traditional capture hoods, the ergonomic design makes the Series SAH easy to maneuver, with less physical stress. The rugged polypropylene base hood features Quad Flow Design Technology for controlling air flow and minimizing back pressure, which yields superior measurement accuracy. The Wi-Fi direct communication gives reliable communication with a distance of up to 200 yards (183 m) between the hood and the handheld test instrument. The SMART Air Hood® Balancing Instrument includes the PredictAir™ Application Software which reduces the number of steps in the air flow balancing process using Predictive Balancing’s Express Balance mode. Predictive Balancing is a method of predicting the optimal flow set point for each register and the order in which they should be adjusted.


- Quad flow design technology - A patent pending design based on controlling the circulating air patterns providing a more even air flow with minimal backpressure effects. The design results in an accuracy of 3% or better regardless of diffuser types, based on any diffuser in the Dwyer PredictAir application software.
- Predictive balancing - An integrated process that guides the balancing technician on setting the proper air flow values for each diffuser to fully optimize the HVAC system. No more guess work as Predictive Balancing provides the optimal flow set point for each sequential terminal.
The ergonomic design is much lighter and easier to work with than the existing bulky air hoods, providing greater maneuverability and less physical strain. One technician can complete the air balancing
Wi-Fi direct wireless communication provides a range up to 200 yards (183 m)
