The honeycomb panel frames are used to hold the honeycomb panel material in place and to reference the honeycomb panels to equipment chassis ground potential. The frame comes with a spiral EMI gasket for panel bonding on either Spira-Cell or Brass-Cell filters.
The extrusions used for the Spira-Cell and Brass-Cell filters have built-in dovetail grooves. These grooves are used to hold the spiral EM bonding gasket in place during the manufacturing process and allow the gasket to move unrestricted during compressed applications. This unrestricted movement allows the gasket to absorb movement of the joint surfaces during thermal expansion and contraction, vibration and shock. This results in reliable EM bonding between the honeycomb panel and the frame throughout the life of the filter.
All of the standard filters use a 1/8” cell. Other cell sizes are available through special order. Contact us for availability.
The standard panel thicknesses are 1/8” (Aluminum only), 1/4”, 1/2” or 1”. Contact us for availability.
Filters can be made either with through holes of varying sizes or fitted with threaded inserts. For cost efficiency, we recommend even spacing of holes. Threaded inserts are not available on the 1/8” thick panels.
The high humidity/salt spray versions use our edge tin/lead plated beryllium copper gaskets and are available in the following configurations:
Spira-Cell: Tin plated aluminum frame and honeycomb panel (or chem-film plated for “light” salt-fog)
Brass-Cell: Tin plated brass honeycomb panel with tin plated aluminum frame
RoHS compliant versions also available on request.
Static Pressure Drop Versus Air Speed
All honeycomb filters are made-to-order to your specifications. Please send a drawing that specifies the following information:
- Size of Filter: Length and Width
