SHIELDED VENT PANELS
ECS400 SERIES
ECS400 aluminum shielded air vent panels are created from an aluminum honeycomb medium installed in an aluminum casing. The honeycomb allows for maximum levels of shielding while ensuring the least possible re-sistance to air flow.
APPLICATIONS
Recommended use for East Coast Shielding ECS 400 vents is to install into electric equipment enclosures that require high levels of EMI shielding as well as sufficient ventilation. East Coast Shielding vents can be installed necessitating on either the inlet or outlet air flows.
AVAILABLE CONFIGURATIONS
Our vents are typically assembled from 0.500” (12.70) thickness, 90-degree aluminum honeycomb with a cell size of 0.125” (3.18), but the honeycomb is also offered 0.250 (6.35) thickness and cell sizes of 0.062” (1.57) and 0.188” (4.78). Slanted cells are also available at 30, 45, and 60 degrees from the horizontal for drip proof construction. Vents with panels including captive inserts (with or without-holes) are available for mounting pur-poses. The finished construction can be chromate conversion coated or tin-plated for additional protection. East Coast Shielding vents are supplied with attached mesh, strip, or conductive silicon fabricated gaskets. For addi-
