Voir AF400 Adsorption filtration products   The lubricating oil and grease inside the LiDAR bearings will emit PFPE, which will adsorb on the radar optical components and affect the optical and radar perception and capture of information. Voir® AF400 can significantly adsorb volatile PFPE oily substances and filter acidic gases, greatly reducing the amount of oil adsorbed on radar optical devices.Voir ® The AF series adsorption filtration products are applied in fields such as semiconductor microelectronics-disk drives, precision instrument equipment-sensors, control systems-lidar, etc. Voir® AF400 is a specialized adsorption filtration product for LiDAR.
