The Finesse TruFlow gas manifold design leverages the well-known “gas stick” concept used in semiconductor process tools – wherein gases only come into contact with clean metallic surfaces. The TruFlow gas manifold interfaces easily with the Finesse G3 utility tower family. This gas control system consists of up to six mass flow controllers and associated solenoid valves attached to a manifold: it can direct each gas to one of two or three independent headers / spargers. The digital gas mainfold units are hot-pluggable into Finesse utility / control towers and are auto-detected by the software. The TruFlow Gas Manifold maximizes safety (gas does not come into contact with electrical wiring), maintains UL compliance, and facilitates planned maintenance of the system.


  • Compatible with Finesse G3 Controllers
  • Compact but scalable
  • Hot-swappable with digital control
  • Gas contacts only metallic parts for cleanliness
