Tech-Etch manufactures a range of EMI shielded honeycomb vents, fan vents, quiet vents and air filters from prototype to high volume in all shapes and sizes. In-house plating improves shielding effectiveness and environmental protection, while providing fast turnaround. Many RoHS compliant finishes are available.
Honeycomb bents are offered in both standard and custom configurations. Shielding is accomplished with 1/8-cell aluminium honeycomb panels, and can be increased by using two 1/4-inch thick panels in a cross-cell configuration. Nine different aluminium vent styles are offered, and additional shielding gaskets can be added to increase attenuation.
Shielded fan vents with optional dust screens provide high airflow without degrading fan output. A BeCu gasket can be added to the frame and six standard sizes are offered. Quiet vents with honeycomb media provide maximum air flow through openings requiring shielding to 90 dB attenuation levels. Since the honeycomb design yields 95% open vent area, the unrestricted air flow results in reduced turbulence and lower noise levels than vents constructed from perforated metal. Lightweight, aluminium frames come standard with a Twinseal gasket for shielding between the frame and the mounting surface.
