Custom EMI Vent Panels and Shielding Filters for Electronics Enclosures
Aluminum Honeycomb EMI Shielding Filters with Integrated Airflow
UAF manufactures custom EMI vent panels and shielding filters for electronics enclosures that require both electromagnetic interference protection and ventilation airflow. Constructed with aluminum honeycomb media, these EMI filters deliver high shielding effectiveness at low resistance to airflow, making them well suited for enclosures where thermal management and EMI/RFI protection are both required.
UAF designs and manufactures each panel in custom dimensions, frame profiles, and honeycomb configurations to meet the specific shielding and filtration requirements of the application.
As one of the few dedicated EMI vent shield manufacturers in the U.S., UAF combines in-house engineering, prototyping, and production to deliver custom shielding and filtration from a single source.
High performance shielding solutions
Custom EMI vent panels are the ideal solution for electronics enclosure applications with high frequencies and limited space. Products are configured with aluminum honeycomb and provide low resistance to airflow and thin profiles. Edge-to-edge venting requirements and intricate designs are met with precision metal fabricated aluminum frames and housings.
Trusted by OEM Teams Across Telecom, Defense, and Electronics
Custom EMI Vent Panels attenuate EMI noise with positive grounding to enclosures. Air straightening and air diffusion are a standard feature for applications requiring thermal management. Products are custom designed to meet specific application needs and are configured with EMI gaskets, spring clips and other attachment hardware to improve installation and contact.
The aluminum components are usually treated with special RoHS compliant protective finishes to provide corrosion protection. EMI Vent Panels typically use 0.12” cell honeycomb in 0.12” and 0.25” thickness, but other components like slanted 45 or 30 degree honeycomb and mesh screens are also specified.

Frequently Asked Questions
What is an EMI vent panel?
An EMI vent panel is a component that provides electromagnetic shielding while allowing air to pass through an enclosure for cooling. They typically use aluminum honeycomb media, which blocks electromagnetic energy while maintaining low resistance to airflow. EMI vent panels are used in electronics enclosures where both thermal management and EMI/RFI protection are required.
What is the difference between an EMI vent panel and a power line EMI filter?
EMI vent panels and shielding filters are mechanical components that block radiated electromagnetic interference at enclosure ventilation openings while allowing airflow for cooling. Power line EMI filters are electrical components that suppress conducted electromagnetic noise on power and signal lines. Both serve EMI protection purposes but address different interference paths.
What honeycomb configurations are available?
UAF offers aluminum honeycomb in 0.125″ cell diameter as standard, with media thicknesses of 0.125″, 0.25″, and 0.50″. Straight (90 degree) honeycomb is most common, but slanted configurations at 30, 45, and 60 degrees are available for applications requiring directional airflow control.
Can EMI vent panels be customized for specific enclosures?
Yes. UAF manufactures EMI vent panels in custom dimensions and frame configurations. Panels can be specified with EMI gaskets, spring clips, and other attachment hardware, and aluminum components are treated with RoHS-compliant protective finishes.
