Application Parameters
The SmokeShield PTC™ range of Fire/Smoke dampers are CE Marked ‘ES’ Rated dampers used to prevent spread of fire and smoke maintaining compartmentation. SmokeShield dampers up to maximum width and height dimensions can be used where the operating total system pressure is up to 1500 Pascals and duct velocities to 15m/second. The SmokeShield PTC™ Damper blades are open and fail-safe to the closed position. Dampers may be installed both vertically and horizontally. Airflow can be from either direction. Actionair SmokeShield PTC™ Dampers are designed for applications in normal dry filtered air systems. If exposed to fresh air intakes and/or inclement conditions, the dampers should be subject to a planned inspection programme. For specialist and/or aggressive applications, please contact us.
