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-Cell, Econo-Cell, 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.
