FF Filter Foam Absorber
FF Filter Foam/Vent Absorber is similar in appearance and geometry to conventional ETS‑Lindgren pyramidal and wedge type absorbers and similar to conventional EHP series absorbers in normal incidence and wide-angle performance, while being designed with open cell/reticulated polyurethane foam substrates.

Absorber with Increased Airflow and the Same Excellent Performance
FF Filter Foam/Vent Absorber is similar in appearance and geometry to conventional ETS‑Lindgren pyramidal and wedge type absorbers and similar to conventional EHP series absorbers in normal incidence and wide-angle performance, while being designed with open cell/reticulated polyurethane foam substrates.
The large pore size allows for easier airflow through the absorbers and can be used over air vents while also handling up to 10 times the power density of conventional foam absorbers. Filter Foam absorber can also handle more RF power since the open cell design allows for better heat release.
