VENTECH ring jet diffusers are inconspicuous and discharge air long distances to the occupied zone. They can be adjusted electrically or manually and work in heating or cooling modes. Ring jet diffusers are used for preference where the supply air from the diffuser has to travel a large distance to the occupied zone. This is the case in large rooms (halls, assembly rooms etc.), particularly when the distribution of air via ceiling diffusers is not possible or not practical. Here ring jet diffusers are arranged in the side wall areas  





  • Nominal sizes 100, 150, 200, 250, 300, 350, 400. Multi ring jet diffusers type available by fixing 2, 3, 4 ring jet diffusers into flat rectangular face panel.

  • The direction of the air stream from the ring jet diffusers can be easily adjusted manually to suit particular on site conditions. The inner core movement can be adjusted within the range of ± 30°. And each ring can be adjusted any directions to allow air flow throws to any directions.

  • The wide range of designs available, the flexibility in adapting to local conditions and compliance with low noise requirements mean that VENTECH ring jet diffusers can be used in almost any air conditioning system.

  •  Diffuser made of aluminum, powder-coated.

  • For long distance supply air.

  • High induction results in a rapid reduction of the temperature difference and airflow velocity.

  • Aluminum panel optional.
