This catalogue provides convenient
quick sizing tables for fire dampers.
The volume flow rates for all available dimensions
and nominal sizes are provided based on
a particular differential pressure and a given
sound power level (35 or 45 dB(A)).
Sizing data for other volume flow rates and
differential pressures can be determined quickly
and precisely using the Easy Product Finder
design programme.
