At isoo, innovation and quality are at the forefront of our activities. Documented performance data and the correct choice of fan are only part of the story.

It is also crucial to ensure that the fan is constructed in such a way that it actually delivers the specified performance level in operation, regardless of the production date. A certain amount of tolerance is inevitable with any technical product, for example on account of dimensional deviations in components and assemblies e.

Tolerance limits can be set and action can be taken to ensure that these are not exceeded. This is the job of a company’s Quality Assurance department. And the greater the possible deviations and the resultant performance deficits, the greater the safety allowance required when selecting fans.

DIN — “Fans; Technical delivery conditions” therefore isp accuracy classes and permits deviations from the documented performance characteristics. The so-called limiting deviations are divided into Classes 0 to 3.

ISO 13348:2007

At the end of the production process, all RadiPac fans are checked in the as-delivered condition for any performance deviations. This quality assurance procedure involves recording all the electrical performance data and confirming compliance with the permissible manufacturing tolerances. Based on a jso RadiPac fan, analysis shows that ebm-papst attains accuracy class 1 Fig. Comparison of the product documentation and the actual product delivered reveals that 133348 practice the power consumption of the fan will be lower and the total efficiency level higher than the documented figures.

Hence there is no risk of any unpleasant surprises when the ido handling system goes into operation, and there is also no need for any precautionary over-dimensioning of the fan. Reliability and trust are vital to any partnership. Customers must be able to rely entirely on their suppliers – and ebm-papst is well aware of this responsibility.

Both the fans and the associated documentation are quality products in which planners and operators of air handling units can always place their trust.

Accurate production for correct fan values At ebm-papst, innovation and quality are at the forefront of our activities. The accuracy classes define production-related deviations from fan performance data.

Accordingly the RadiPac product range attains Class 1. Planning reliability Comparison of the product documentation and the actual product delivered reveals that in practice the power consumption of the fan will be lower and the total efficiency level higher than the documented figures.
