This VPU (Voice Projection Unit) is solid, and designed for quick attach and detach. It fits the M40, M42, MCU series, Millennium mask (and any with the same front voicemitter ring), even those with a mic input jack protruding from the front like some MCU models and the M42.

The VPU makes a person’s voice clear and distinct, which is a critical necessity for tactical units such as SWAT teams and the military. Once fitted, the VPU is securely attached and allows for weapons firing.

Compatible with MSA Millennium, Advantage 1000, and 3M FR-M40 Gas Masks; NIOSH approval for effectiveness against chloroacetophenone (CN), chlorobenzylidene (CS), and oleoresin capsicum (OC) tear gas; Uses 2 triple(AAA) batteries for up to 18 hours of continued use; Condition Voice Amplifiers are in like-new condition, and are fully functional.

Clip on VPU for MCU2P mask specifically. It clears the plug on the front of the mask and clips onto the sides rather than screwing on. It will work with any similar MSA mask of the time (m40, millenium, etc) but check my page for the threaded VPU as well if that's what your after.

Dec 24, 2021 · I’m having issues with this MSA M40 VPU. It’s practically brand new, it was sealed and everything, but when I put the battery in and turn it on it just makes this faint static noise. Share

Apr 18, 2020 · From what I've seen they're made for the Millennium and Advantage 1000 masks which look to have the same diaphragm as an M40 and MCU-2/P. Was curious if anyone can confirm if they'll mount properly or if there's a specific VPU I should keep an eye out for.
