VAV B 40 Series
Induction Type
Type: Rectangular / Round
Construction: Galvanized Steel (GI) / Stainless Steel
Application: Light & Medium Duty
Induction VAV Model GB-41 is pressure-independent VAV where air volume control terminals are designed particularly for systems with high variations in heat load. The terminals induce room air and mix it with conditioned primary air, maintaining a nearly constant air volume to the room thus providing sufficient air movement necessary to maintain occupant comfort even in extreme load variations ensuring cold air ‘dumping’ will not occur and comfort zone will be maintained under extremely low primary air temperatures, without producing excessive differences between the supply and the room air temperature.
Data
Technical Features:
- Volume control range from 100 to 10% is possible to the
conditioned zone. - Accurate airflow sensing with 2 X 12 points averaging.
- 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. - Suitable for low temperature primary systems.
- Air volume capacity upto 2800 CFM
- Suitable for use as constant volume application
- 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.
