Variable Air Volume Flow Control - VARYCONTROL

<< ONLINE SHOP PAGE

Circular Air Terminal Units for Variable Air Volume (VAV) Flow systems, for the control of supply air or extract air, suitable even when upstream conditions may be unfavourable. These units enable a highly precise yet simple setting and measurement of the volume flow rates. Our production facilities are fully equipped with air test rigs, so that every unit leaves the factory perfectly set up to exact customer requirements.

VAV units work with an external power supply and can be used for controlling, restricting, or shutting off the airflow in room air conditioning systems. Depending on their construction configuration the units can meet even the most demanding acoustic requirements with its whisper-quiet operation; different materials and surface finishes are also available.
