Feature

  • Patent pending Quad Flow Design Technology directs the circulating air patterns to provide a more even air flow that minimizes backpressure enabling accurate readings.
  • Predictive Balancing is a process that guides the balancing technician on setting the optimal flow set point for each sequential terminal.
  • With the PredictAir™ Application Software, the balancing process takes much less time than traditional air balancing methods.
  • The ergonomic design is much lighter and easier to work with than the existing bulky air hoods, providing greater maneuverability and less physical strain. One technician can complete the air balancingOptional.
  • Wi-Fi direct wireless communication provides a range up to 200 yards (183 m).
