Air Flow Capture Hood User Manual

Air Flow Hood is a portable test equipment instrument that indicates volumetric air flow through grills, diffusers and registers. Applications include commissioning, testing, adjusting, and balancing volumetric air flow from diffusers, grilles, and registers in HVAC systems.

Question
Why should I buy a SMART Air Hood®?
Answer
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 standand wireless communications to the handheld, a single operator can balance a branch in less time than traditional balancing teams. Besides being lighter thanmost traditional capture hoods, the ergonomic design makes the Series SAH easy to maneuver, with less physical stress. The rugged polypropylene base hoodfeatures patented Quad Flow Design Technology for controlling air flow and minimizing back pressure, which yields superior measurement accuracy. The Wi-Fidirect communication gives reliable communication with a distance of up to 200 yards between the hood and the handheld test instrument.

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 terminaland 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 keyand 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 onwhere to go to set the proper flow for each register allowing the system to be fully optimized. 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 Balancingis a method of predicting the optimal flow set point for each register and the order in which they should be adjusted.

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 pressurecompensation. These factors contribute to wasted energy and poor performance. Dwyer’s patent pending, state of the art, Quad Flow Design concept is based oncontrolling the recirculating air patterns that can create back pressure effects, while mixing the flow more evenly and efficiently. This well mixed flow for velocitysampling leads to superior measurement accuracy.

Question
Where do I send the SMART Air Hood® to be calibrated?
Answer
Recalibration of the SMART Air Hood® is fast and easy. Dwyer recommends recalibrating the Hood, at a minimum, once a year to ensure maximum performance.When it is time for recalibration, simply detach, by unclipping the clamps on all four sides, the four Quad Flow Sensing Grids along with the Sensor Module. TheQuad Flow Sensing Grids and Sensor Module need to be calibrated together. For your convenience, Dwyer includes with each purchase of a SMART Air Hood® acustom return calibration package specifically designed for the four Quad Flow Sensing Grids and Sensor Module. To ensure no downtime, you can purchase a newset of four calibrated Quad Flow Sensing Grids and Sensor Module, model A-SAH-CK part number 100765-09, ready to install on the jobsite. You can return theoriginal four Quad Flow Sensing Grids and Sensor Module in the custom return package to Dwyer using our RMA process or to any authorized Dwyer calibrationservice company.
