Applied Materials AFC-550 Mass Flow Controller

Applied Materials AFC-550 Mass Flow Controller is a nitrogen-specific gas metering device designed for integration with AMAT process equipment. The unit regulates nitrogen flow in the 20 to 1000 standard cubic centimeters per minute (sccm) range, providing precise setpoint control for gas delivery in semiconductor process environments. As a mass flow controller, the AFC-550 monitors flow and modulates gas throughput to maintain stable process conditions, helping to achieve consistent deposition or etch performance where nitrogen is used as a carrier or purge gas. Identified by the AFC-550 model number from Applied Materials, this controller is part of AMAT’s family of flow-control components intended to deliver reliable, repeatable gas control within compatible tooling. When encountered in listings or inventories, the AFC-550 is typically described as a nitrogen mass flow controller with a 20–1000 sccm range, enabling operators to select a compact, medium-range solution for tight process gas management. Use cases typically involve precise regulation of nitrogen flows in gas-handling subsystems of semiconductor fabrication equipment, ensuring accurate flow measurements and timely response to control signals.
