1)
Temperatures may differ for units with attachments. Details for other applications are available on request.
2)
Data applies to uniform upstream and downstream conditions for the fire damper.
3)
Condensation and the intake of humid fresh air have to be avoided as otherwise operation will be impaired or not possible.
4)
Leakage rate of the fire damper system tested at 300 Pa and 500 Pa negative pressure.
