Series SAH22A SMART Air Hood
Specifications - Installation and Operating Instructions
The SERIES SAH22A SMART Air Hood
and easy to operate air flow hood on the market. By using the included hood stand
and wireless communications to a handheld device with the Dwyer Instruments
PredictAir
application software, 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 SAH22A easy to maneuver, with
less physical stress. The rugged polypropylene base hood features patented 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 between the hood and the handheld
test instrument. The PredictAir
application software 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.
