Iris regulating damper

Galvanised round iris regulating damper with manual
control, equipped with 2 manometer connections for airflow
measurement. The iris-type closure allows airflow control
with low turbulence and duct noise. The lever and iris
regulating plates mechanism allows smooth adjustment of
the orifice opening. The iris damper can be fully opened for
easy cleaning of the ductwork. However, the iris damper
cannot close completely, in fully closed position there will
still be about 25% free passage. The casing airtightness
meets class C according EN1751. Both flange connections
are fitted with EPDM gaskets.

Airtight casing: Class C EN12237
Galvanised steel sheet
