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