Measurement and control damper with iris function

Type-approved method of measurement
Short installation length
Can be cleaned
Low flow-generated noise level
High measurement accuracy
Ductwork leakage class C, EN 1751

Function
- Volume control, Measurement and control

Design

The control function itself is built into a surface-mounted collar and offers uniform and centric throttling when the damper blades are actuated towards the centre. The result will be a laminar and uniform air stream pattern with a low noise level. Thanks to its compact design, SIRI is simple to integrate into the ductwork. Casing leakage is according to ductwork leakage class C (EN 1751).
