Vent Panel Options & Finishes.

Finishes:

Our standard surface finish is KEM-PAS. Kemtron is leading the market with this new coating which fully meets the RoHS Directive for the elimination of hexavalent chromium in electrical & electronic equipment. This new coating fully meets the performance requirements of MIL-C-5541E for corrosion and electrical conductivity. The finish is a golden yellow colour, similar in appearance to Alocrom 1200. Other finishes available to special order are Alocrom 1200, Nickel and Tin Plating.

Painted Finishes:

We are able to offer a comprehensive range of painted finishes to complement our standard Kem-Pas finish. Using industry leading wet paint solutions from Trimite, we offer full painting and preparation to DEF STAN specifications including matt and gloss finishes. In addition we can also offer Infra Red Reflecting (IRR) matt finishes complying with DEF STAN 00-23, 80-166 and STANAG 2338.

For less critical / commercial applications requiring a protected finish we recommend polyester powder coating. This is tough material that offers excellent resistance to fresh and saltwater, petrol, linseed and penetrating oils, along with limited resistance to various acids. We are happy to advise on specific examples if required. As the epoxy process is an electrostatic method, it offers excellent penetration of the honeycomb cells, further aiding resistance to corrosion. With both processes, we are able to offer a full range of colours to RAL / BS charts

Kick Plates:

For high traffic areas or where honeycomb damage could easily occur kick plates can be fitted. Two types are stocked as standard, however custom designs to customers specific requirements (i.e louvred openings) can be discussed and fitted if requested.

Expanded aluminium style:

Woven Stainless Steel mesh:

Provides maximum protection but reduced airflow

Provides lower protection but with better airflow

Gaskets:

Frame styles 1702 & 1703 are supplied fitted with solid monel mesh EMC gasket as standard. Tin-plated Copper Clad Steel (TCS), Aluminium or Stainless Steel solid mesh can also be specified if required. All other frame styles can be supplied with many different types of EMC gaskets including knitted mesh bonded to an environmental seal, oriented wires in silicone, conductive fabric over foam or beryllium copper.

Fixings:

Vents are normally supplied with drilled clearance holes to customer specific sizes. Inserts are also offered and are stocked in M3, M4 & M5 sizes. Other styles and sizes are available on request.
Standard tolerance on Hole Centres is +/- 0.4mm

Welding:

Vents are normally supplied with three notched and one welded corner to achieve the best trade off between cost and performance. This combined with an EMC gasket is normally sufficient for all but the most demanding EMC specifications. In the event that the best possible attenuation is required all corners can be supplied fully welded. Please note that styles 1702 & 1704 are always supplied fully welded due to the nature of their construction.
