BCF floor diffusers are designed for installation in raised floor systems like auditoriums, conference rooms, theatres, where a high level of comfort and conveyance is required. Air is supplied into the space through the front panel at a low velocity, mixing with room air above the diffuser.

Supply air velocity must be very low to reduce discomfort that may be felt in the near zone. We recommend designing as a displacement system with a maximum supply temperature of 3°C below room. Supply 10 to 15 l/s per unit and allow a distance between outlets of 0.8 to 1 meter.

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.
