Description
IRIS diaphragm damper for air flow regulation
IRIS diaphragm damper is a modern and efficient air flow regulation device designed for precise balancing of ventilation systems. It ensures that the supply or exhaust air volumes are balanced according to design requirements. Unlike traditional throttle or vane ventilation dampers, this design operates on the diaphragm principle – the air flow area is reduced or increased evenly in a circular shape.
Such a solution provides several essential advantages:
more stable air flow,
less noise in the duct,
higher regulation accuracy even at low air flow rates.
Main advantages of the IRIS damper
✅ Precise air flow regulation – the circular diaphragm design allows the damper to narrow or expand evenly, so the air flow regulation remains accurate and stable throughout the entire working range.
✅ Lower noise – the air flow flows more evenly, reducing turbulence and whistling sounds that are often characteristic of vane dampers.
✅ Compact solution – one damper performs the entire regulation function, no additional elements or extensions are required in the duct.
✅ Easy installation – with the help of fasteners, the damper is mounted directly to the diffuser trim ring, without requiring additional space.
✅ Universal application – can be used for both air supply and exhaust in various ventilation systems.
Where are IRIS diaphragm dampers used?
IRIS dampers are a reliable choice when it comes to ensuring high comfort and air quality. They are widely used:
in office buildings, where a comfortable microclimate is important,
in hospitals and laboratories, where precise balancing of air flows is required,
in production facilities, where it is necessary to ensure proper ventilation,
in residential buildings and apartment buildings, in order to balance the supply and exhaust air volumes.
👉 IRIS diaphragm air damper is the optimal solution if you are looking for reliable, precise and quiet air flow regulation for your ventilation system.
