Description
Fire dampers WH45P are devices for use in heating, venti-
lation and air-conditioning (HvAC) systems at fire bounda-
ries to maintain compartmentation and protect means of
escape in case of fire. They satisfy integrity, insulation and
smoke leakage criteria for the declared time of fire resistan-
ce.
Tested and classed in accordance with EN 1366-2 and EN
13501-3 regulations with 500 Pa depression (300 Pa for in-
stallations with Weichschott sealing).
Studied and optimized for medium and big diameter ducts
focusing on aeraulic and acoustical performance.
