This luminaire had been in use for 10 years in a coke plant. When the polycarbonate cover was removed, it was discovered that the inside of the luminaire still looked shiny and new.
The air current caused by the lighting fixture heating and cooling is passed through a filter, which captures dust and other dirt particles. Such impurities are removed from the air by either the filtering microfibre paper, the activated charcoal element or the GORE membrane. This ensures that no impurities get onto the surface of the specially treated reflectors in such a way that would cause them to emit a dimmer light or damage their sensitive LED chips or electronics.
Energy consumption and the need for maintenance decrease and lighting life cycle costs reduce considerably.
The larger I-Valo dual-effect filters include an activated charcoal element in addition to the microfibre paper. They also filter out different gases in addition to dirt particles. The choice of filter is made based on the ambient conditions in the installation environment.
