The "Spira Advantage"
Spira’s family of exceptional honeycomb filters includes our Shielded
Fan Filter, as well as our popular Econo-Cell,
Spira-Cell, and Brass-Cell Shielded Air Vent Filters. All Spira honeycomb filters include the “Spira Advantage” as described below.
Spira's Patented Process
All Spira Shieldied Air-Vent and Fan Filters include our patented “blending” process
of the aluminum honeycomb panel that provides high and reliable
levels of shielding. Our filters also include the use of epoxy
which mechanically bonds the honeycomb panel to the frame and the
use of our patented spiral EMI gasket, which ensures an excellent,
long-lasting EM bond between the panel and the frame.
The shielding effectiveness graphs illustrate the shielding of
1/8” cell by 1/4” thick honeycomb panels including:
(A) the level of shielding obtained from a typical honeycomb
panel; (B) the shielding from a panel which has been processed
using our patented blending process; and (C,D) the shielding
obtained from tin plated honeycomb panels, where most of the
incidental contact points across the epoxy joint were removed
from one of the panels during the pre-plating cleaning process
of Spira Filters
