Kemtron-Icon-EMC

EMI Shielding Ventilation Panels

Kemtron’s EMI shielding vent panels or attenuvents are made from aluminium or steel honeycomb mounted into a frame. Many aluminium frame styles are available together with different thicknesses and configuration of honeycomb to meet different shielding requirements. Protective grilles are available for vulnerable areas together with dust filtration foams. Many plated or painted finishes can be specified.

Aluminium Panels Kemtron

Aluminium honeycomb vent panels for air flow consist of an aluminium honeycomb foil held in a rigid extruded aluminium mounting frame. The foil, formed and laminated into a series of honeycomb cells that are glued and perforated or laser welded at the join, ensures a conductive path at each join. Although the foil is conductive in all directions, to enhance EMI performance, two pieces of honeycomb polarised at 900 to each other are recommended.

Shielding is achieved by using Waveguide design principles (Honeycomb Cell dia X length by 4). The frame can be supplied with an integral or separate EMI/RFI gasket, and can be treated with a variety of finishes to provide corrosion protection or improve conductivity.

Ventilation Panels Kemtron

Aluminium EMC & dust filter ventilation panels consist of 3 layers of pleated aluminium woven mesh trapped between an expanded aluminium kick-plate then held in a rigid extruded aluminium mounting frame, The frame can be supplied in a range of sizes and profiles and panels can be treated with a variety of finishes to provide corrosion protection or improve conductivity.

Ventilation Panels can be provided with additional EMI gasketing or environmental sealing if required for extra emi and sealing protection.

Ventilation Panels Kemtron

Aluminium screen EMC & dust filter ventilation panels consist of multi-layer expanded aluminium foil mesh trapped in a rigid extruded aluminium mounting frame, the frame can be supplied in a choice of sizes and profiles. Ventilation panels can be treated with a variety of finishes to provide corrosion protection. Ventilation panels with a gasket groove have a knitted Monel wire mesh gasket as standard. Other frames can be provided with an additional EMI Gasket for extra EMI and sealing protection.

Aluminium Panels Kemtron

Steel Honeycomb Vent Panels are designed for high performance applications, where high attenuation is required particularly in the H field.

Steel Honeycomb Vent Panels consist of a steel honeycomb foil soldered in to a rigid fabricated mounting frame. The foil formed and laminated into a series of honeycomb cells that are welded at the join, ensures a conductive path at each join.

The frame can be supplied with an integral or separate EMI / RFI gasket, and can be treated with a variety of finishes to provide corrosion protection or improve conductivity and EMP protection.
