DATA SHEET Thermal Mass Flow High Purity/Ultra-High Purity Digital Mass Flow Devices GF100 Series Designed for semiconductor, MOCVD, and other gas flow control applications that require a high purity all-metal flow path, the Brooks® GF100 Series mass flow controllers and meters deliver outstanding performance, reliability, and flexibility. Highlights of the GF Series industry-leading features include: ultra fast 300 millisecond settling time, MultiFlo™ gas and range programmability, optional pressure transient insensitivity (PTI), local display, extremely low wetted surface area, and corrosion resistant Hastelloy® sensor tube and valve seat. The GF100 Series has been marathon tested to over three times the semiconductor industry standard for reliability, ensuring repeatable low-drift performance over time. An independent diagnostic/service port permits users to troubleshoot or change flow conditions without removing the mass flow controller from service. The flagship GF125 is a second generation multi-variable, pressure transient insensitive mass flow controller. This product builds upon Brooks’ leadership position in pressure transient insensitive (PTI) mass flow controller technology, minimizing process gas flow variation due to pressure and temperature fluctuations. The GF125 enables customers to simplify and reduce the size and cost of gas panels by eliminating the need for point of use pressure regulators, pressure transducers, and associated hardware. MultiFlo™ gas and range programmability, a patented technology developed and refined by Brooks over the last 10 years, has changed the mass flow controller industry by offering customers the ability to select new gas calibrations and full scale ranges without the trouble and cost of removing the mass flow controller from the gas line. The GF Series fourth generation MultiFlo technology continues to lead the market with the most accurate and broadest range performance through extensive refinement and physical validation on critical process gases. The GF100 Series is a highly configurable platform based on a novel modular architecture. Already widely adopted by semiconductor, vacuum thin film, solar, and related customers, the GF100 Series feature set was carefully selected to enable drop-in replacement and upgrade of most brands of metal-seal mass flow controllers, including the former Celerity, UNIT, Tylan, and Mykrolis brands. With the wide range of options and features available, the GF100 Series provides users with a path to simplification and standardization, greatly reducing spares inventory and support costs.
