b.safe Service Life Indicator for Exhaust Filters and Air Valves

The service life of a b.safe Exhaust Filter / Air Valve can be easily and reliably monitored with the practical service life indicator. It is activated at the touch of a button and the white field starts to turn red. The colour bar does not fill linearly. Initially it runs relativelyfast, so that the release is immediately visible after pressing the button, and then it slows down. There are marks for 3, 6 and 12 months on the field. When the field is completely coloured red, the lettering „Change“ appears, and the exhaust filter or air valve should be changed. Alternatively, the change date and, if applicable, the name sign (for example for audits) can be notedby hand on the backside of the service life indicator or next to the service life indicator.
