  • Page 4 Working conditions Dampers are designed for smoke exhaust piping systems with underpressure max. 1500 Pa or overpressure max. 500 Pa. Dampers are designed for maximum air velocity 12 m/s. Dampers are installed with the horizontal or vertical axis of the blades. Dampers are intended for installation on air ducts and in/onto the walls where in the case of wall installation, this wall with damper does not have fire resistance and therefore does not separate two fire compartments.
