Brooks Instrument GF126 High-Flow PTI Mass Flow Controller

About this part

Brooks Instrument GF126C-200158 is associated with the GF126 high-flow thermal mass flow controller line. Brooks defines GF126 as a high-performance, high-flow model with pressure-transient insensitivity and integrated inlet-pressure measurement; the following C denotes MultiFlo capability. The published GF126 model envelope is 55–300 slpm N2-equivalent. The 200158 suffix is not defined by the published configuration-code sequence, so the configured gas, full-scale range, valve, fitting, connector, communications, calibration, and customer-special requirements are not established by this identifier alone

Configurations vary. Verify the exact unit before choosing a replacement.

What Does GF126C-200158 Mean?

Only the GF126C prefix can be decoded from Brooks’ published product-code structure. The suffix must remain uninterpreted without an exact manufacturer record or readable physical label.

SegmentFieldInterpretation
GFBase model codeHigh-purity/ultra-high-purity digital mass flow controller platform.
126Package and performance modelCurrent Brooks documentation defines GF126 as high-performance and high-flow with PTI; its model-code table assigns a 55–300 slpm N2-equivalent envelope and integrated pressure measurement.
CConfigurabilityMultiFlo capable.
-200158Secondary suffixNot defined as a valid continuation of the published GF100 Series configuration-code sequence. Do not assert a gas, range, fitting, connector, CSR, or other option meaning from this suffix.

Configuration Software Status

MultiFlo capability does not identify the gas or full-scale range currently programmed into the controller.

Legacy utilityBrooks states that MultiFlo Configurator remains downloadable but is no longer supported.
Current recommendationBrooks recommends its supported Expert Support Tool (BEST) where compatibility and continuing updates are required.
Copy-exact cautionBrooks advises controlled users to evaluate software and FloCom database changes before updating approved configurations.
