The stated air flow and sound level were recorded under the following measurement parameters: Centrifugal fan mounted on a foundation plate 140 x 140 mm. Cover plate 140 x 140 mm, with an air inlet opening Ø 94.4 mm, arranged concentrically to the impeller. Speed control range from 800 rpm-1 at 7% PWM up to nominal speed at > 90% PWM. Standstill at 0% PWM, maximum speed if control cable is interrupted. The specific service life is valid when an external capacitor is wired between the positive and negative wires. Please note the wiring suggestion. Tin-plated 112 2016-01 Air performance measured according to: ISO 5801. Installation category A, with ebm-papst inlet ring without contact protection. Noise: Total sound power level L WA ISO 103002 measured on a hemisphere with a distance of 2 m; Sound pressure level LpA measured at 1 m distance from fan axis. The values given are applicable only under the specified measuring conditions and may differ depending on the installation conditions. In the event of deviation from the standard configuration, the parameters must be checked after installation!
