Product Description

MS 400

The MS400 Semiautomatic manifold reduces compressed gases of max. 300 bar to a continuous gas supply of 18-20 bar. It is designed for the use with 2 gas sources (cylinders or cylinder bundles). However, one side at time is the operating one and the other is then the reserve side. The MS400 will ensure continuity of gas flow by automatically changing from a nearly empty side to a full (reserve) side. MS400 is a complete valve unit with high pressure filters, isolating valves, purge valves, regulators, auto change unit and low pressure pipe with line shut-off valve. Components are assembled and mounted at stainless steel wall bracket. Inlet x-block contain free port for extension to more gas sources.

MS400 can be used for inert gases as nitrogen, argon, CO2 and their mixtures. It is optimal solution for continuous gas supply for industrial applications as e.g. welding & cutting, assist gas supply for laser cutting, different inertization, food packaging and many other applications. There is also variant with contact gauges giving information about switching over to reserve side to responsible person.
