SPI-300°C Iris damper. Manually set damper 300mm diameter for supply or extract air.
Description
The SPI is an iris damper for measurement and adjustment of the air flow. The SPI has the following specifications: low sound level, centrically formed air flow and fixed test points for precise measurements. This device can be used for supply as well as for extract air.
Design
The damper is manufactured from galvanised sheet steel and is fitted with a rubber gasket tested for air-tightness in class C according to EN 1751. It has an adjustment aperture which can open the entire cross-section, so there is no access door for cleaning required. Available in sizes ø 80-800mm.
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 the deviation. The SPI enables taking precise air-flow measurements at all points including points close to T junctions and bends, and points in front of air ducted or terminal devices.
