100% Opening capacity The SPI can be fully opened,eliminating the need for an access door for clea- ning purposes. Low Noise Generation The design of the adjustment function together with the geometry of the SPI, results in low noise generation under volume control.A conventional damper will increase the air velocity along the duct walls resulting in high generated noise under volume control.The 'Iris' aperture is close to ideal from a flow technology aspect.The Iris damper increases the air velocity with low levels of noise generation provided the instructions are followed in relation to the...
