CPR01 – Pressure Relief Damper
The type CPR-01 Pressure Relief Damper has been designed to give maximum efficiency under arduous conditions and is suitable for the air outlets of electrical equipment rooms, control rooms and living quarters. These areas are maintained at a higher pressure than surrounding areas to prevent the ingress of hazardous gases.
The differential pressure is usually 63 N/m² although this may be increased to provide a greater safety margin. The dampers may be installed vertically or horizontally with the airflow upward.
