Product Overview

It is a diffuser that can control the direction of airflow with a blade. It is divided into S type and D type according to the number of slots.

Number of slots 1 2
Control of Diffused Airflow Direction and Air Volume Since the direction of the airflow can be adjusted up to 45° to the left and right by using the blade,
the airflow distribution in the room can be properly maintained.
There is very little static pressure loss and air volume change due to the change in the direction of the airflow.
Structure and Appearance A blade that can control the direction of the airflow is attached. When the blade is removed, it can be used for
suction and exhaust. The diffuser is made of aluminum, which is light and sturdy, and the exterior is beautiful.
2 The diffuser and chamber (Chamber/Plenum Box) are integrated
by fixing it with screws to the mounting hooks.
Since the gasket (option) is attached to the instrument frame(option) and adheres to the ceiling surface, contamination of the ceiling surface due to suction and discharge can be prevented.

*1 Noise level: Measured with a microphone at 45° angle from the outlet and 0.9m away (noise level reduced by 8db under indoor conditions)

*2 The vertical distance reached until the residual wind velocity of the airflow with a terminal velocity of 0.5m/s becomes 0.25m/s.

*3 The horizontal distance reached until the residual wind velocity of the airflow with a terminal velocity of 0.5m/s becomes 0.25m/s.
