GF80 Series Metal Sealed Thermal Mass Flow Controllers & Meters

Raises the standard in performance for value-driven metal sealed applications.
Models GF80 / GF81
For many industrial and semiconductor processes, both performance and cost efficiency are crucial. The GF80 Series metal sealed mass flow controllers and meters deliver both: Engineered using the same fast response sensor and patented 4th generation MultiFlo™ technology as our best-selling GF100 series, it’s the right choice for operations that need high performance at a value price point. Moving to a metal sealed MFC brings the full benefit of MultiFloTM multi-gas/multi-range capability since there are no limitations in gases that can be used, enhanced purity of the gas due to elimination of oxygen permeation through elastomers, and a reduction in maintenance since metal seals will last indefinitely.

Features

  • Long-term zero stability of <±0.5% full scale per year
  • <1 second settling times
  • Full-scale flow rates up to 300 slpm
  • All-metal seal flow path - 16µ inch Ra surface finish
  • Corrosion-resistant Hastelloy® sensor can operate at lower temperatures for gases prone to thermal decomposition
  • Programmable MultiFloTM capability—one device, thousands of gas types and range combinations without removing the MFC from the gas line or compromising accuracy
  • Best-in-class temperature coefficient specification through active temperature compensation
  • Embedded self-test routines and independent diagnostic/service port
  • Slimline body with VCR fittings
  • DeviceNetTM, Profibus®, RS-485 and analog interfaces

Benefits

  • Fast <1 second flow settling time eliminates wasted gas and process variability
  • No elastomer seals that can have oxygen permeation, requiring replacement over time
  • MultiFloTM simplifies and streamlines changing process gases — no more removing and calibrating MFCs
  • New gases and/or ranges can be set in under 60 seconds
  • Measurement accuracy not affected by temperature variations
  • Convenient access to diagnostics port for maximum uptime
  • Compact size eases integration into tight machine spaces; excellent choice for retrofits
  • Multi-protocol communication interface simplifies integration into existing systems

Applications

  • Cost efficient retrofit/upgrade of legacy MFCs in refurbished semiconductor process tools
  • Reduce MFC inventory in six-inch/eight-inch semiconductor fabs
  • MOCVD for LED and power device manufacturing
  • Solar/thin film chemical vapor deposition (CVD) systems
  • Analytical OEM equipment
