Quantity Available:


If you are looking for a option that changes your Nitrogen over automatically from one pack to your reserve, then look no further.
With 300 bar inlet pressure to accept EHP N2 packs and a massive 40 bar outlet pressure, the Druva Tec high flow, 100m³/hr semi auto manifold has the performance to match your application.
Bolt it to the wall, match this with LifeGuard EHP safety hoses in pack lengths, connect to your pipework. Done.

> Metallic sealing of the shut-off valves and pressure regulators to the atmosphere by Elgiloy/Hastelloy
> No increase of outlet pressure with decreasing inlet pressure due to the use of a pressure regulator with
inlet pressure compensation
> Very compact design
> Easy installation of the manifolds by using split plates in the stst backing board

> Shut-off valves- Design and production in accordance with ISO 10297 including oxygen ignition test for main
shut-off valves
> WITT Safety Relief Valve – pipeline protection
