* Function type is optional.
* The max. air ow and the speed are measured in free air ; max. air pressure is measured at zero air ow.
* Noise is measured in anechoic chamber in free air, one meter from intake side.
* All readings are typical values at rated voltage.
* Specications are subject to change without notice.
