Voice Projection Unit for the Canadian C4 Gasmask. These use AAA batteries and HAVE been function checked.
These devices are meant to clip onto the front of a C4 mask to boost the audibility of the user.
Very rare piece, the “nose” piece of the C4 needs to be outfitted with the “VPU Kit” in order to accept these devices. Example photo shown in the gallery. These may work with other Airboss Masks, but it cannot be guaranteed.
