Patent No. EP4091697 (titled "Separation System For Paint Overspray") was filed by Brain Flash Patententwicklungs on Mar 2, 2015. The application was issued on Aug 28, 2024.
A set for cleaning airflow comprises a hollow body (5) with an inlet opening (6) and an outlet opening, and multiple cleaning substructures (7) serving as separating structures (1) for particle separation or filtration. The hollow body is configured to accommodate at least two different combinations of cleaning substructures. At least one separating structure (1) includes at least two flaps (11) aligned substantially parallel to the airflow. These flaps are configured to act as spacers against the hollow body's inner wall or another separating structure, enabling the arrangement of an additional separating structure between the flaps. This modular configuration allows the set to adapt to various paint contamination types, particle sizes, and moisture contents by adjusting the total thickness of the cleaning substructures.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
