Barriers to Dust, Dirt, and Moisture
Filter and venting materials can act as barriers to dust, dirt and moisture, protecting the components within a product while allowing air and sound to pass.
Acoustic Mesh
Acoustic Mesh is acoustically transparent while acting as a barrier to dust and moisture, protecting and extending the life of the device. Visit our Acoustic Mesh Page!
PTFE Vents for Pressure Equalization
Airflow through vents allows pressure to equalize within environmentally sealed enclosures (according to IP67) which protect the enclosure contents from damage. [Download IP Rating and NEMA Rating Charts]
Micro-sized Vents + Filters
Marian also has the advanced capabilities to manufacture extremely small vents and filters, down to 2 or 3mm in size.

Precision Selective Lamination
During the die cutting process, Marian often laminates filter and mesh materials with pressure sensitive adhesive cut to a zone, leaving the central portion of the filter or vent free to breathe. Additionally, Marian can add layers of other thin materials to meet the desired function of the final part. Marian excels at precise selective adhesive lamination.
In the rendering above, final die-cut parts adhere to a liner on a roll which is used for automated placement within the customer’s assembly.
