The RKP-C is a round mechanical CAV damper designed for constant airflow regulation in ventilation systems. It does not require external power supply and is made of galvanized steel. The device operates efficiently at airflow velocities between 3 and 8 m/s and pressure differences above 50 Pa. Flow rate adjustment is manual, via a screw on the cover. With a temperature range of –20°C to +80°C and class C airtightness, it is an ideal solution for passive ventilation control in residential and commercial buildings.

• Made of galvanized steel sheet.
• Recommended air velocity 3 to 8 m/s, at differential pressure >50 Pa
• The required constant quantity is adjusted by turning the operating screw on the right side of the cover.
