Vav Units

Overview:

Circular and Rectangular VAV terminal unit for use in variable air volume systems at low airflow velocities even under unfavourable upstream conditions

• Effective tubeless pressure monitoring via damper blade
• Effective pressure transmission through pressure channel in shaft
• Terminals with protective cover – no junction boxes required
• Any direction of flow with dynamic transducer
• Suitable for airflow velocity of 0.5 – 13 m/s
• For volume flow rate ranges up to 36,000 m³/h or 10,000 l/s
• Compact dimensions for use in confined ceiling areas
• Exact measurement even at low airflow velocities
• Any installation orientation even with static transducers
• Closed blade air leakage tested to EN 1751, at least class 3
• Casing air leakage tested to EN 1751, class C
• Volume flow rate range 1:25

Typical Applications

• Circular and Rectangular VAV terminal unit for use in room air conditioning systems (HVAC systems)
• Also for unfavourable upstream conditions at low airflow velocities for supply air or exhaust air flow control in variable air volume systems
• Closed-loop volume flow control using an external power supply
• For controlling, restricting, or shutting off the airflow in air conditioning systems
