CR7050 Navitek S4 Airkos Main Filter

The Navitek CR7050 Airkos Main Filter is designed for use with the Weltek air fed welding & grinding helmets and fits inside the Airkos blower unit. The main PRSL filter is protected by the CR7060 pre-filter which prevents its lifecycle.

The Airkos clogging alarm sound will notify when the main filter should be changed. The user can also change more frequently if deemed appropriate.
