Technology Details
Modular Conversion to a Passive Filter
The adapter frame is designed as a direct replacement for the auto-darkening filter cassette (ADF) in Optrel liteflip series helmets. Its design allows a standard passive glass filter measuring 110×90 mm to be mounted securely and stably. This lets the welder easily turn an advanced auto-darkening helmet into a classic helmet with passive protection. It is the right solution for specific applications, such as welding at high currents with a single process, where a fixed shade is fully sufficient, or as an economical backup plan. This adapter gives you continuity of work and flexibility that make you independent of a single type of technology.
Standardisation and Full Flexibility
Using the world's most common passive filter size, 110×90 mm, is the key advantage of this adapter. It frees you from searching for non-standard, dedicated solutions and gives you access to the many affordable passive filters available on the market. This standardisation makes equipment management easier in larger workshops and allows consumables to be unified. For the individual professional, it means a free choice of shade and filter manufacturer, as well as noticeably lower operating costs in the long run. It is an investment in versatility and independence that lets you optimise costs without compromising the fit in your Optrel helmet.
