• It is a prismatic section fixed air adjustment damper designed to pass the set air flow completely mechanically without any power source in ventilation systems.

• Mechanical fixed flow adjustment dampers are self-adjusting with the spring-operated mechanisms of the desired air flow, regardless of the pressure change in the system.

• They are used in blowing or exhaust lines.

• Since there are no engines, they were more economical than motor types, and they do not require maintenance.

Accuracy in the study is within ± 5% band.

• Desired air flow rate can be adjusted on the device.

• They can be used in the pressure range of 50 Pa to 1000 Pa and in the air inlet speed range of 2 to 10 m / s (recommended).

• Notes for installation and adjustment: See. Catalog

• For size & flow compatibility, sound levels, pressure losses
