The EM3 was an Italian gas mask made by Pirelli for industry use.

Mask overview Edit

The EM3 mask's facepiece was made of a two layers beige rubber, textured on the outside and smooth on the inside. The head harness had five straps, two of which had hooks to quickly don the mask without having to field adjust. The lenses were made of triplex glass. Inside the mask, there was a sponge layer that helped to reduce the dead space inside the mask and to prevent fogging while wearing it; this sponge-section design varied slightly from the Penna respirator to closen the eyepieces to the eyes so to give a better field of view. The inlet-outlet assembly 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 inlet valve. The filter itself was attached through a corrugated hose to the aforementioned piece and itself was kept in its bag or cage carrier.

The EM3 was very similar to the EM2, with only three small differences:

  • The eyepieces are larger and allow a better peripheral vision
  • The lower straps sport a hook system
  • The hose is extendable, allowing smoother movement

Filter Edit

The mask was issued with a Tubin or Turnivercio filter, containing various blocking substances that depended on the kind of protection required in the buyer's working condition.

Kit Edit

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. With these kits, the buyer could also get anti-fogging soap, anti-fogging lenses and a spare exhale valve.
