Premo filter

Premo is a set of two different size of three-phase voltage filters.



The aim of the project was to update the design and manufacturing process of these filters. The client wanted to avoid the maintenance issues that their filters’ design had and, at the same time, change their manufacturing process from folded metal sheet to plastic injection production.


The final design was formed by three different plastic parts. The base where all the electrical components were installed. The cover that closed the assembly without having to use screws which meant that it could also be disassembled pretty easily unlike the previous design. And finally, the small windows on the cover that allowed an easy access to the primary and non-hazardous components in case of an electric failure.
