VAV B 10 Series

By Pass Type – AHRI

Type: Rectangular / Round

Construction: Galvanized Steel (GI) / Stainless Steel

Application: Light & Medium Duty

 

In Pressure Dependent VAV Model VAV-GB-21/22 , the room thermostat modulates the VAV box damper directly to control the space temperature. This requires that the duct static pressure be maintained at designated levels so that enough air pressure is available to cool the room.

 

The terminal unit damper is positioned from a signal sent directly from the zone thermostat to the damper actuator without regard for system conditions. In a pressure dependent system, two zones on the same system are effected by the control of one another.

Technical Features:

  • AHRI Certified.
  • Test Conducted at minimum static pressure at 100% of standard airflow.
  • Full range of control of variable air volume supply from 0 to 100% is possible to the conditioned zone.
  • A minimum air volume set in terms of percentage (20%) can be provided if required, field adjustment is also
    possible.
  • Low Leakage i.e. less than 2% of V nominal at 750 Pa.
  • Designed to produce low NC levels with minimal pressure drop to the system.
  • Air volume capacity upto 2800 CFM
  • Electronics control factory supply & mounted.
  • Variety of control options available, based on applications.
  • Electronic thermostat & actuator provide accurate mounting control.
  • Metal encapsulated edges limit fiberglass insulation erosion into the airstream.
  • Single-point power connection reduces installed cost.
  • Maintenance free.
