Shielding Vents

4 corners of 4 different vents

Aluminium honeycomb ventilation panels are used in electronic enclosures where EMI shielding and heat dissipation are required. These are available in any size to suit your requirements with a choice of material thicknesses and frame profile. 


  • Cho-Cell (plated honeycomb aluminium)
  • Shield-Cell & Omni-Cell (shielded vent panels)
  • VIP (Viscous Impingement Vents)
  • Shieldscreen (3-layer mesh dust vents)
  • Stainless Steel Honeycomb Vent Panels
  • Steel & Brass Honeycomb Shielded Vents
  • Streamshield EMI Vents

A honeycomb vent is either a free-standing metallic alloy honeycomb or an assembly incorporating the honeycomb with other value-added features, such as: framing, plating, gasketing, filters, etc. These vents are typically incorporated into enclosures where EMI radiation or susceptibility is a concern, as well as where heat dissipation is necessary to ensure long-term assembly performance.

Application-specific performance can be changed by modifying the size and other associated features of the vent assembly. Design requirements such as (but not limited to): attenuation values, airflow rates and direction, corrosion prevention, durability, air particulate filtration and flame resistance can be achieved.

Honeycomb material selection:

  • Aluminium (single layer & unplated)
  • Aluminium (omni cell 2 layer & unplated)
