Puravent 6757 SPI-315 C Iris Damper
Description
Technical details can be found here
The SPI is an iris damper for measuring and adjusting the air flow. 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
adjustment aperture which 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 galvanised sheet steel and is fitted with a rubber
seal tested for air-tightness. 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 minimise air-flow deviation. Reducing or enlarging the duct to the
next duct size does not require any specified distances for minimising
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

- after“ – 1 x D
