GF135 Series Real-Time Flow Error Detection Metal Sealed Thermal Mass Flow Controllers

Performance and intelligence.
Models GF135

Keep critical flow processes on-target and maximize throughput with the GF135 Advanced Diagnostics Pressure Transient Insensitive (PTI) mass flow controller. The world’s first “smart” mass flow controller is a true game changer: It performs integral rate-of-decay flow measurement without stopping the flow of process gas. It allows semiconductor manufacturers to verify process gas accuracy, check valve leak-by and monitor sensor stability in real time without removing the flow controller from the gas line.

Combined with an all-metal wetted flow path, ultra-fast settling times and industry-leading process gas accuracy, the GF135 PTI MFC has the potential to transform the productivity and throughput rates for a wide range of deposition processes.
