Description and photos
AJ-3M apparatus is an appliance similar to other hose apparatuses. The main difference being it does not require the access to electric grid or compressed air line. For it's use compressed air tanks are required, but contrary to AS-3M, here the compressed air is not only used for breathing but rather for powering the injector.
The compressed air is directed to the injector's nozzle, creating a negative pressure in a suction chamber, to which through an air filter the atmospheric air is sucked in and pumped through a hose to the user.
I only have the main belt for this apparatus.
