The FG-130, FGP-130, FG-13 and FU-13 were box filters available in the Soviet Union, where they were used for protection against hazards found in industrial and agriculture manufacture. These filters were mostly issued with the ShMP kit.
Filter overview[]
Outwardly, it looks similar to the EO-16, sharing the same dimensions and overall shape, however, later the EO.1.08.01 (PMK-1 filter) shape was also used. Interestingly the "M" and FG-13 SO filters use two male GOST threads on either end, instead of the standard Soviet filter arrangement of one GOST thread and the intake sealed by a rubber plug. The M and SO filters are noticeably heavier than the others because it contains hopcalite (MnO2 and Cu2O in 3:1 mixture) to filter out carbon monoxide. Most FG-130s weigh in the region of 1100 to 1200 grams. During manufacture, the filters were painted the appropriate colour or colours with no basecoat. In the filters inlet or intake there is meant to be a blob of paint to indicate what filter it is, if the outside is damaged. Sometimes FU-13 filters with extra particle layers and no bottom thread are marked with an ink stamp saying A/V/G/E/KD2.
It is hard to establish the exact manufacturing timeline for these filters. The filter pictured above is dated 1971 and it is known that this filter design survived into the post-USSR period. It was probably used until the mid or late 1990s.
