Description and photos
AS-3M "Arcus" is a hose apparatus for breathing the compressed air from an airline or tank. The air is first directed into the FPO-1, FPO-2 or FPO-3 oil filter. Then is supplied to the main belt with a regulating valve. The user can control the airflow to the mask or to the spray gun, which can be used with this appratus
An interesting difference between a newer and an older version is the corrugated hose - in older versions the hose was fitted with additional exhale valve.
On the FPO-1 oil filter's page I've shown it's construction in a more detailed manner.
On the FPO-3 oil filter's page I've shown it's construction in a more detailed manner.
