Infrazor is a filter for observing materials melted in metallurgical furnaces, where there is high temperature. The filter guarantees necessary protection against harmful radiating which takes place in the process of melting materials. It absorbs harmful infrared radiation in the range of 780 – 2000 nm as well as UV radiation.

The filters are produced in various levels of protection, depending on the temperature in the furnace. Metallized Infrazor with a protection level of DIN 7 is used in furnaces, where the temperature reaches 1650°C. The filter thickness is 2.2 – 2.8 mm. Maximum accessible size of the metallized filter is 400 x 200 mm.
