Our ECR dedusting filter systems have been present on the global market for several years for the most demanding pharmaceutical applications. Among other things, they have been specially developed to reliably protect operators and repeatedly stay below the OEL limits. With the considerations described above, we at TRM Filter have decided to optimize and improve containment solutions for ECRs. During the development process we implemented many ideas that came directly from our end users – people who work with dust collectors every day in the production process. In the working sessions, they were presented with various options in the form of mock-up models and prototypes. The result of several sessions and iterations is a design perfected down to the smallest detail that ensures the best possible user experience, even with the most demanding HSE requirements.
