The Halton TRF auditorium diffuser is designed for installation in raised floors in auditoriums, theatres, concert halls, where good indoor climate conditions are required.

The recommended supply air temperature is less than 3°C below the ambient temperature. The supply airflow rate is up to 15 l/s per unit. Where requirements for comfort are perceived to be less important, higher airflow rates can be used, resulting in increased velocities close to the diffusers. In such cases diffusers should be installed further away from continuously occupied areas.
