GF120C-916430 is a configured Brooks Instrument 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, but no verified official one-part specification for GF120C-916430 is currently available Sonisys auction history currently includes two tracked listing records for this exact configured code, with one stored title identifying N2 and both stored titles carrying 3030-16835 context. Verify gas, full-scale range, controller configuration, valve state, communication option, fitting package, and any customer or AMAT markings from the physical unit label before reuse
Unit-specific configuration
Observed configuration
Historical listing records identify this part as N2. 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.

Brooks GF100/GF120/GF125 documentation lists repeatability and reproducibility of +/-0.15% of set point from 5-100% and +/-0.015% full scale from 2-5%
Family settling-time context
Brooks GF100/GF120/GF125 documentation lists normally closed valve settling-time bins from 300 ms to less than 700 ms across documented flow bins, depending on configuration
Materials
Wetted path standard
Brooks GF100/GF120/GF125 documentation describes SEMI F20 HP compliant wetted materials
Wetted materials context
Brooks GF100/GF120/GF125 documentation lists wetted material context including 316L VIM/VAR, Hastelloy C-22, 316L stainless steel, 304 stainless steel, KM-45, and PCTFE on optional zero leak-by valve configurations
Controls
Communication interfaces
Analog/RS-485, DeviceNet, or EtherCAT depending on configured model and electronics option
Flow
Gas/range programmability
MultiFlo gas and range programmability is supported on applicable GF-series configurations
Ratings
Operating temperature context
Brooks GF100/GF120/GF125 documentation lists a 10 C to 50 C operating temperature range for documented family configurations
Configuration
Configured-unit rule
Gas, full-scale range, communication interface, valve or meter configuration, fitting package, seal package, surface finish, and process options vary by configured model code
Observed configuration
Stored auction gas evidence
N2 appears in one stored listing title for this exact configured identifier
Secondary marking context
3030-16835 appears in both stored listing titles; one title labels it as AMAT context, so verify the marking against the physical unit label before using it as a procurement identifier
