FMD 300-14/-18

The FMD 300-14 consists of manual cylinder connection with knurled nut (supplied), pressure regulator, upstream pressure gauge, downstream pressure gauge, relief valve and screw connections. The FMD 300-18 has in addition a regulating valve at the outlet. The customary hose fittings and couplings are available as accessories (see ordering information). The inlet on the back end allows for particularly space saving installation.


The cylinder pressure regulator series FMD 300 is attractive for its high flow rate values and good regulating characteristics. The FMD 300-14 is used anywhere where gas is directly taken from the cylinder and greater flexibility for the end user when choosing a location for use.
