Heavy duty type Bypass , Pressure Independent and Pressure Dependent VAVs’ are manufactured for high pressure applications
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 use as constant volume application,it can
maintain a set flow requirement, compensating for
fluctuations in system pressure. - Suitable for single duct variable volume control
- 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.
- AHRI Certified
