Puravent 6758 SPI-400 C Iris Damper
Description
Technical details can be found here
The SPI is an iris damper for measuring and adjusting the airflow. The SPI has
the following specifications: low noise level, centrically-formed air flow,
and fixed test points for precise measurements. The damper also has an
adjustable aperture that can be opened completely, which means there is no
need for an access door for cleaning. Available in sizes ø 80-800mm. The
damper is manufactured from galvanized sheet steel and is fitted with a rubber
seal tested for air-tightness. The permitted ambient temperature is 70 °C.
This device can be used for exhaust air.
Mounting
The SPI adjustment damper must be installed in accordance with the distances required to minimize air-flow deviation. Reducing or enlarging the duct to the next duct size does not require any specified distances for minimizing deviation. The SPI enables the taking of precise air-flow measurements at all points including points close to duct deviations such as T junctions and bends, and points in front of other supply-air devices.
Protective distance
- before bends – 1 x D
- after“ – 1 x D
- before T-pipes – 3 x D
- after “ – 1 x D
- before supply-air
