GF120C-107924 is a configured Brooks Instrument GF120CXXC metal-sealed thermal mass flow controller identifier in the Brooks GF100 / GF120 / GF125 family. Official Brooks GF100/GF120/GF125 documentation covers the metal-sealed platform, communications, MultiFlo support, dimensional configurations, and installation/operation guidance. Sonisys auction history currently includes two active tracked listing records for this exact configured code, with exact listing evidence identifying GF120CXXC model context, 50 SCCM gas/range context, EtherNet/IP and surface-mount fitting context. exact listing evidence is inconsistent on gas wording, with one tracked listing title reporting CHF4 and a surplus listing page reporting CF4, so verify gas, range, communication option, fitting package, valve state, and any customer-specific configuration from the physical unit label before reuse
Unit-specific configuration
Observed configuration
Historical listing records identify this part as CHF4 at 50 SCCM. Exact gas, range, fittings, valve configuration, and communication interface must be verified from the physical unit label.
Configurations vary. Verify the exact unit before choosing a replacement.

Identification
Part identifier
GF120C-107924
Device type
Metal-sealed thermal mass flow controller
Observed model context
GF120CXXC appears in exact listing evidence for this configured code
Series family
Brooks GF100 / GF120 / GF125 metal-sealed mass flow family
Applications
Application domain
Semiconductor, MOCVD, thin-film, and high-purity process gas flow control
Performance
Family accuracy context
Brooks GF100/GF125 analog and DeviceNet documentation lists +/-1% of set point above 35-100% and +/-0.35% full scale over 2-35% based on factory N2 calibration
Family settling-time context
Brooks GF100/GF125 documentation lists normally closed valve response from 300 ms to less than 700 ms across listed flow bins
Materials
Wetted path standard
Brooks GF100/GF125 documentation describes SEMI F20 HP compliant wetted materials
Controls
Communication interfaces
Analog/RS-485, DeviceNet, EtherCAT, or Ethernet-based options depending on configured model and electronics option
Flow
Gas/range programmability
MultiFlo gas and range programmability is supported on applicable GF-series configurations
Observed configuration
Reported gas and range
50 SCCM appears in exact listing evidence; gas wording conflicts between CHF4 and CF4 across exact listing evidence, so verify against the physical unit label
Reported interface
EtherNet/IP appears in exact surplus and listing evidence; verify against the physical electronics option
Reported fitting
Surface mount appears in exact listing evidence; verify against the physical manifold interface
Configuration
Configured-unit rule
Gas, full-scale range, communication interface, valve state, fitting package, seal package, and process options vary by configured model code
