This weather proof pyramid absorber saves you money in the long term and is suitable to be applied in a cleanroom environment. The lightweight structure material is covered with a 10 [µm] thin film offering a high impedance against radio waves. The applied material is non-combustible according to DIN 4102 class A2 and in addition meets the cleanroom specifications of ISO 14644-1 class 5. In contradiction to carbon filled foam absorbers these pyramids are easily cleaned and will not be able to release carbon dust.

Advantages are:

• High absorbing properties
• Highly reproducible properties
• Since the pyramids are hollow, they can be stacked for storage
• No degradation or (downwards) deformation
• Weather proof
• Long life expectancy
• Easily cleaned
• No release of carbon dust
• Non combustible
• Non toxic

All together these properties keep you long term ownership costs low.
