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 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 setpoint for each sequential terminal. The PredictAir Application Software completes the balancing process in much less time than traditional balancing methods.

Ergonomic design: Made from a rugged, lightweight polymer construction; it is the smallest, lightest and most aerodynamic design in the industry. The Series SAH 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.

Mobile speed: With the digital handheld test instrument and software, featuring Wi-Fi direct wireless communications and a range of up to 200 yards (183 m), the testing, adjusting and balancing process is faster and more accurate than any other air flow hood on the market today.

Lowest cost of total ownership: Fast, accurate and easy; a better way to air balance saving time and money. The Series SAH features a rechargeable lithium battery backed up by four AA batteries. For annual calibration, simply detach the removable quad flow sensing grids and sensor module and return without the hood for calibration. To ensure no downtime, simply snap on another calibrated set quad flow sensing grids and sensor module.
