Ball jet diffusers

Photo of product family: Ball jet diffusers


The KHA ball jet diffuser is intended for supplying fresh air to high and very large areas, including theatre halls, cinema auditoria, or industrial bays. The high volumetric airflow from the diffuser has a low sound pressure level and provides a very long airflow range.

The ball jet diffuser can be installed for supplying air either horizontally or vertically. The ball jet nozzle can be adjusted in any direction within 30˚ from the centreline without affecting the airflow resistance or the sound pressure level. The KHA ball jet diffuser has a male inward connection.


The ITG long-range round vane supply diffuser is designed for providing high air supply rate. The temperature of the air supplied can be lower by up to 12˚C than the indoor temperature. This enables using ITG diffusers in cold storage rooms. The air flow angle can be adjusted in the range of 15˚ to 30˚. The air flow cohesion can be adjusted by rotating the diffuser by 180˚ in either direction.
