Fan guard-EMI-shields

Material: stainless steel (spring V2a) material no. 1.4310/AISI 301
Material thickness: 0,2 mm
Equals guideline: EG 2011/65 (RoHS) & EG 1907/2006 (REACH)

The premium fan guard EMI-shields are manufactured in etching technique. The use of fan guard EMI-shields ensures the typically desireable condition, that technical equipment does not disturb each other by unwanted electronic or electromagnetic effects. By a test an improvement regarding EMI-tightness could be determined overall the frequency range, in peaks up to approximately 50 %.

Additionally fan guard EMI-shields function as a touch protection and/ or prevent the absorption of filtermaterials while existing just one wide opening in the housing box. The fan guard EMI-shields can be mounted either at the inside or at the outside of the housing wall. The inside installation has the advantage, that the fan sleeve squeezes directly the fan guard EMI-shields onto the shiny inside wall or by using a plastic-case onto the metallic coated inside wall. The fan guard EMI-shields seal up the fan opening in techniques of electromagnetic compliance. The skinny grill made from stainless steel takes care of EMI-protection and a maximum of air circulation at the same time.

Quite different by comparison with a use of a plastic-/ or a customary guard grill or a perforation in the housing box, an essential noise alteration by the fan guard EMI-shield is almost not existing when the fan is working.
