Optrel Inner Cover Lens for b630/p330 (1 pc.), 5000.370
A genuine Optrel inner cover lens for b630 and p330 series helmets, 1 pc. The inner lens is a key protective barrier for the heart of the helmet, the auto-darkening cartridge (ADF). Replacing it regularly is a basic part of equipment maintenance: it keeps optical quality high and fully protects the expensive filter from scratches, spatter and dirt that come from the inside. It is an essential item for every professional who cares about the reliability and life of their protective equipment.

Technology details
Direct Protection of the Auto-Darkening Cartridge (ADF)
The inner cover lens is the last and most important line of defence for the technologically advanced and costly ADF. Placed between the welder's eyes and the cartridge, it protects it from accidental scratches, dust and small spatter that can get inside the shell. Replacing a worn or scratched lens regularly is far more economical than an expensive repair or replacing the whole ADF module. Investing in this basic consumable is the simplest way to protect a key component of the helmet and extend its life.
Consistent Optical Clarity
Even the best auto-darkening filter with optical class 1/1/1/1 loses its advantages if the image is disturbed by a scratched or hazy inner lens. Micro-scratches and dirt scatter light, causing eye fatigue and headaches and making it harder to judge the weld pool accurately. Replacing the lens with a new, crystal-clear one immediately restores full transparency and viewing comfort, so you can use the full technical potential of the helmet. It is a key investment in precise work and in the protection and comfort of your own eyes.
