During the exhibitions Cleanzone and Semicon in autumn 2018, COLANDIS GmbH presented the prototypes of the Mini-Fan-Filter-Modules. 

Joachim Ludwig has become an expert in cleanroom applications for technology industries. He thinks that a big cleanroom isn't always the best solution for the process and the product. He is very successful with his motto "the best cleanroom is the one you don't need" for more than 20 years.

In industries such as micro, and semiconductor technology working in controlled surrounding conditions has been standard for a long time now. Cleanroom technology has been viewed sceptically by injection moulding and the sense of this technology has been questioned. Meanwhile even in plastics processing a change in its views has taken place.

For a zero-fault production concerning a justifiable clean production the entire process chain needs to be taken into consideration. If only one part of the process has been neglected, all other production steps lose their effect and the product loses its quality. Therefore, not only the single component purification but also the purification of the assemblies and complete machines are of utmost importance.
