Air Purge Collars [SF15/ SF02/ 2W/ 2WM-2]
The lens must be kept clean at all times from dust, smoke, fumes and other contaminants in order to avoid
reading errors. These effects can be reduced by using an air purge collar. Make sure to use oil-free,
technically clean air, only.

The needed amount of air (approx. 2...10 l/ min.) depends on the application and the installation
conditions on-site.
