FAH Large Hollow Pyramidal Absorber

 

FAH Large Hollow Pyramidal Absorber
Features：
It is mainly an absorber made with rigid foam as a carrier. Compared with solid pyramids of the same thickness of 1.5 meters or more, the biggest advantage is light weight, low cost and non-sag tip.
It is suitable for the rear wall of the low-frequency anechoic chamber and the Fresnel zone. It is also suitable for the construction of large EMC chambers.
 
Characteristics：
Appearance: light blue hollow single-pyramid.
Fire retardant: Meet the NRL REPORT 8093 TEST 1, 2, 3 of US Navy and the B2 requirements of national fire protection.
Power capacity: 0.12W/cm²
Operating temperature: -50°C ~75°C
