Dwyer Smart Air Hood - Advanced Air Balancing Capture Hood with 12ft Extension Pole
Quad Flow Design Technology, Predictive Balancing
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.

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.
An industry first for airflow balancing, this patent pending process 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 application software completes the balancing process in much less time than traditional balancing methods.
Made from a rugged lightweight polymer construction; it is the smallest, lightest and most aerodynamic design in the industry, weighing less than 6 pounds and 1/4 the height of other bulky air hoods. The Series SAH SMART Air Hood mounts to an extendable pole for easy use and maneuverability resulting in less muscle strain compared to other air balancing equipment. Balancing can be completed by just one technician.
With the digital handheld test instrument and software, featuring Wi-Fi direct wireless communications and a range of up to 90 yards, the testing, adjusting and balancing process is faster and more accurate than any other air flow hood on the market today.
Fast, accurate and easy; a better way to air balance saving time and money. The SMART Air Hood features a rechargeable lithium battery backed up by 4 AA batteries resulting in no downtime. For annual calibration, simply detach the removable pitot arrays and pressure sensor and return without the hood for calibration. To ensure no downtime, simply snap on another calibrated set and you are back in business.
The SMART Air Hood balancing instrument comes standard with a 2 ft x 2 ft (0.6 m x 0.6 m) opening but can also be used with other diffuser / register sizes using a required adapter base kit (A-SAH-BK) and various adapter hoods. Available adaptor hood sizes, sold separately, include a 1 ft x 4 ft model A-SAH-14S, a 2 ft x 4 ft model A-SAH-24S, a 3 ft x 3 ft model A-SAH-33S, a 4 ft x 4 ft model A-SAH-44S and a 1 ft x 5 ft model A-SAH-15S.
