The Czechoslovak FM-3 was mainly produced for industrial and civilian purposes.

Mask overview Edit

FM-3 Edit

The facepiece is made of moulded gray rubber. The round triplex eyepieces are held by black painted steel assemblies. The valve house is made of bakelite and clamped to the faceblank with a single metal strip. Instead of the Tissot-tube system on the previous FM-1 and FM-2 there is a bakelite cone on the intake which only allows the air to go upwards, defogging the eyepieces when inhaling. The 6 point head harness was simplified as well. The rubberised bands connect to moulded in metal buckles, there is a clamped metal part on the end of each strap which stops it in the buckle. There are two slabs on the back where the straps connect to and the harness can be adjusted there by two pull tabs.

FM-3a Edit

The same as the normal FM-3 but it has a gray stockinette cover on the rubber and it has a carring carrying strap which connects to the bottom strap.

FM-3b Edit

Not much is known about it.

FM-3c Edit

It has textured faceblank. Also called as Lidová C.

FM-3d Edit

The rubber was made thicker near the buckles to make the faceblank stronger.


Markings Edit

Several markings can be found on the mask, the most notable is the "FATRA" logo on the exhale valve (only on the ones which were made by Fatra). Most of them are stamps with legal and quality control meanings. The size of the mask can be found on the left temple (1-2-3).

Filter Edit

Mostly FF-3 and CHF-1 filters were used with this mask.

Kit Edit

Carriers for the mask vary, probably depending on the price, from cardboard tubes to sturdy metal canisters. Even the metal canister had two different types, one tall cylindrical similar to the Romanian and Italian carriers of the time period and a short but wide rectangular with rounded side.

The kit contained:

  • Mask
  • Filter
  • Carrier
  • Anti-fogging soap
  • Short manual

External information Edit

Export and foreign use Edit

Netherlands Edit

Two companies in The Netherlands imported FM-3d masks. G.L. Loos & Co. Fabrieken N.V. form Fatra and Cidex N.V. from Kudrnač. Both were called Rijkskeur 026.

Denmark Edit

It was called Arbejdsgasmaske Model F (Work gas mask Model F) in Denmark. The Danish government imported a bigger amount of FM-3 masks and with CHF-1 filters because the domestically produced M.1931 and M.1938 couldn't be produced in enough great numbers.

FinlandEdit

Finland imported FM-3d masks from Fatra in 1940-1941 probably because of the Winter War. The masks don't have any special markings but the CHF-1 filters which came with the mask have a SA stamp (Finnish: Suomen Armeija - Army of Finland). These masks also came with thread converters because Finland used 40mm filters while the FM-3 have 42mm connection.

GermanyEdit

After Germany invaded Czechoslovakia some masks were used by the Luftschutz (Nazi German Civil Defence) and by anti-aircraft units. On these masks, the Waffenamt proof stamp can be found.
