ATI 90° Cell and Slant Cell Ventilation Panel

ATI 90° Cell Ventilation Panel is an EMI shielded air filter. Extruded aluminum profiles surround aluminum honeycomb and are welded in place for structural support. Aluminum honeycomb in various cell size and thickness is secured into the channel. 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 90° Cell Ventilation Panel available in brass and steel.
*ATI 90° Cell design available in 15, 30, 45 & 60° slanted honeycomb for the control of air flow direction.
