filter protect hard medium

The bachmaier® protect medium hard filter is the ideal solution for demanding work environments with elevated noise levels up to 101 dB. Perfect for loud workshops and industrial settings, it reliably reduces disruptive noise without blocking out essential acoustic signals such as speech or warning sounds. The innovative nozzle technology enables precise sound attenuation while allowing pressure equalization through micro-ventilation. Two marking dots on the filter cap ensure clear identification during everyday use.
