1/ Description
Ventilated absorbers are manufactured from special reticulated (open cell) foam. When used as a vent material, this
product allows air to move freely.

Absorption @ Normal Incidence
3/ Medium Power Absorber Specifications
When the material is used as a medium power absorber,
it can safely dissipate 1 W/in
2 CW with standard convec-
tion cooling. This is accomplished by the open cell cha-
racteristics of the reticulated foam, which increases the
ability of the absorber to dissipate the heat generated
by the absorption of the microwave energy. For higher
power applications of 2 - 3 W/in
2
CW, material must be
force-cooled.
4/ Pressure Drop Specifications
HVAC professionals use pressure drop calculations to
ensure adequate air flow for proper air turn-over within
a chamber.
