Purge ring
The purge ring is an important accessory when used in
conjunction with the dust tube. When installed, it allows air to
be pushed in between the instrument lens and the dust tube,
thus pushing all forms of dust away from the lens and acting
as an additional barrier against dust.

external commissioning laser device can help you align the

In applications where dust may be present (even in very small
quantities), the dust tube accessory is highly recommended.
