Series SAH SMART Air Hood® Balancing Instrument
Quad Flow Design Technology, Predictive Balancing
AVAILABLE with SAH-22HC HARD TRAVEL CASE!
The SMART AIR HOOD® (SAH) Balancing Instrument is the most accurate and easy to operate air flow hood on the market today. The low profile design allows balancers to work in occupied spaces (bathroom stalls, MRI machines, cubicles, tables/chairs, etc.) and maneuver through doorways easier. By using the included 12 foot hood pole and wireless communications to a mobile device, one 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 technician exude less energy as the SAH has a lighter, balanced design. 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 protocol back to the user’s Android® or iOS® device gives the user real-time feedback, as they may be up to 200 yards (183 m) from the hood which saves the technician from unnecessarily going up and down their ladder multiple times to cut or open the dampers to balance the system.
The SMART AIR HOOD® Application Software reduces the number of steps in the air flow balancing process using Predictive Balancing. Predictive Balancing is a method of predicting the optimal flow set point for each register and the order in which they should be adjusted.

Questions
- Question
- What is Quad Flow?
- Answer
- Traditional industry cone shaped air flow hoods experience two main problems when measuring flow registers; poor accuracy of flow readings and back pressure compensation. These factors contribute to wasted energy and poor performance. Dwyer’s patent pending, state of the art, Quad Flow Design concept is based on controlling the recirculating air patterns that can create back pressure effects, while mixing the flow more evenly and efficiently. This well mixed flow for velocity sampling leads to superior measurement accuracy.

- Question
- What is Predictive Balancing?
- Answer
- The current industry method of balancing is commonly referred to as proportional balancing. Proportional balancing determines the flow between each terminal and the key. The key flow changes with each adjustment of any given terminal, so the balancing technician must estimate a flow for the terminal and adjust the key and the terminal until the correct proportion is achieved. The SMART Air Hood® is designed to provide Predictive Balancing, an industry first for air flow balancing. Predictive balancing guides the balancing technician on where to go to set the proper flow for each register allowing the system to be fully optimized. The SMART Air Hood® Balancing Instrument 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.
