Holyoake HFS motorised fire, smoke, and combination fire and smoke dampers, impede the spread of fire and smoke through ducted air systems whilst maintaining barrier integrity. Self-contained as fire and smoke dampers, and externally operable by a spring return actuator, the HFS damper offers supreme fire and smoke leakage performance due to the unique patented sealing system.
HFS Fire and Smoke Dampers Rating
HFS leakage-rated, fire and smoke dampers have undergone rigorous testing in accordance with AS 1530.4 – 2014 and AS 1530.7:2007, comfortably meeting the stringent leakage integrity rates of 11.6.2.1, aligned with the European ISO Standard 10294-1 ‘S’ Classification.
In fire rating tests conducted according to Standard AS 1530.4 – 2014, HFS fire and smoke dampers demonstrated exceptional integrity for over 4 hours. Compliant with the Australian Construction Code and New Zealand Building Code, they hold an impressive Fire Resistance Level (FRL) or Fire Resistance Rating (FRR) of –/240/–, making them a trusted choice for fire and smoke safety in your projects.
