Leader Tech introduces its high performance EMI shielded air vent panels to its product range. Air vent panels are manufactured using aluminum, steel or brass and are available in various plating finishes and mounting configurations allowing for installation in most applications.
|
|
Metex EMI vent panels provide maximum attenuation with minimal air-flow resistance. Shielding effectiveness is greater than 80 dB at 10 MHz for chromate finished, single layer honeycomb, and is increased to 105 dB using our cross cell construction. By selecting the appropriate frame style, finish, and gasket type, performance can be custom tuned to meet your shielding requirements, and your budget constraints.
Vent panels are constructed of aluminum alloy honeycomb, with a perimeter frame of aluminum extrusion for mounting and gasket application. Various gasket options include wire mesh, spring finger, or conductive fabrics

What differentiates ATI-Circular EMI Vents from other conventional panels is the shape.
Billets, rods, bar and plate stock are fabricated into rigid frames for structural support.
Core materials of honeycomb in assorted thickness and cell size, 3-layer screen, multi-layered screen, rigid grill and combinations may be selected for circular vent assemblies. EMI gaskets and environmental seals can be applied. Plating options enhance shielding effectiveness. Through hole locations are customized for easy surface mount installation with standard 8-32 rivnuts or .203 diameter holes. ATI Circular Vent Panels are designed for a precise fit of round openings on mounting walls or enclosures. Circular Vents are ideal in applications where a conventional rectangular vent may impede mounting space. Alco's special circular vent process can be fabricated in ATI 90° Cell, ATI-Dual Stack or ATI 3-Layer designs.

ATI Dual Stack Ventilation panel is a high level EMI shielded air filter with superior performance. Extruded aluminum profiles surround dual layers of ¼-inch honeycomb and welded in place. Both honeycomb layers are positioned 90 degrees to each other, optimizing shielding effectiveness and minimizing the polarization characteristics of straight aluminum honeycomb. Alco-Multi Gasket, a combination of neoprene sponge and monel mesh or Alco-Knit, is installed on the panel. Hole locations are customized for easy surface mount installation with standard 8-32 rivnuts or .203 diameter holes. Plating options enhance shielding effectiveness.

ATI's brass and steel honeycomb vent panels are recommended when structural integrity, H-Field shielding effectiveness, harsh environmental conditions and durability are primary concerns. Brass or steel extrusions are customized to surround brass or steel honeycomb and welded in place. Continuous flow soldering provides enhanced contact between the honeycomb and frame improving integrity. Alco Multi-Gasket, a combination of neoprene sponge and monel mesh fit, most applications although Alco-Knit or conductive gaskets are available. Standard through holes and spacing for surface mounting installation is customized. Vents without gasketing can be welded in place. Brass vents are typically finished with tin lead plating. Steel vents are commonly finished with tin plating. Other plating options available. Ideal for mobile military transportation, communication shelters or equipment where EMP or TEMPEST is required.

|
ATI-Thin Filter is the thinnest profile EMI shielded air filter. Extruded aluminum surrounds a singular thin piece of expanded monel or aluminum metal screen and welded in place. Alco-Knit or conductive gasket increase shielding effectiveness. Through hole locations are customized for easy surface mount installation. Plating options enhance shielding effectiveness. ATI- Thin Filters are frequently placed at intake and exhaust areas and are best utilized where narrow space limitations are a requirement.
