Linear diffuser LDF is a ceiling-mounted air diffuser with a fixed horizontal air jet, designed for horizontal air supply in variable airflow systems. Utilizing the Coanda effect, it directs air along the ceiling when airflow is low, ensuring even distribution without drafts. Made from powder-coated steel and integrated with an insulated PBL-F plenum box, the LDF diffuser offers durable performance, minimal noise, and a compact design. Ideal for office buildings, retail spaces, and public areas with ceiling heights up to 3 meters.

• Suitable for horizontal supply and variable flow: when the flow is low, the air stream follows the contours of the diffuser (Coanda efect).
• Usable up to 25% of maximum flow rate.
