The EM 3 was an Italian gas mask made by Pirelli for industry use.
Mask overview Edit
The EM 3 mask's facepiece was made of a two layers beige rubber, milled on the outside and smooth on the inside. The head harness had five straps, two of which have hooks to quickly don the mask without having to field adjust. The eyepieces were made of three layers, two glass ones and a cellulose one that tended to become orange over time. Inside the mask, there was a sponge layer that helped to prevent fogging while wearing the mask; this sponge-section design that varied slightly from the Penna respirator to closen the eyepieces to the eyes so to give a better field of view. The intake-outtake piece is connected to the mask at the bottom and it has three holes: one for the hose, one for the connection to the mask and the third was for the exhale valve, kept still by a lid; inside there is an inhale. The filter itself was attached through a pleated hose to the aforementioned piece and itself was stored in its bag.
The EM 3 was very similar to the EM 2, with only three small differences:
- The eyepieces are larger and allow a better peripheral vision
- The lower straps sport the hook system
- The hose is extendable, allowing smoother movement
The mask was issued with a filter that depended on the kind of protection required in the buyer's working condition. The most common filter was the "Tubin", a metal box similar to the one of the Penna.
The mask was used in two configurations. With the first one, the mask came with a satchel similar to the one of the Penna respirator: it had two sections, one for the mask and the other for the filter and hose. The filter section had holes to allow ai flow. The main strap had a special buckle to be shortened when the mask was in use; the small string on the side of the satchel helped to keep the aforementioned firmly onto the wearer's chest. In the second configuration, the filter was put in a small cage satchel on the wearer's chest.
