Product Description
High-Flow Gas Mass Flow Controller for Process and Vacuum Systems
The Series GFC Model GFC-2144 Gas Mass Flow Controller is engineered for accurate, closed-loop gas delivery in industrial and laboratory environments. Covering flow rates up to 500 LPM, this controller integrates a straight-tube thermal sensor with a precision restrictor element to maintain stable performance across changing temperature and pressure conditions.
Designed for automation-driven process systems, the GFC-2144 supports analog control signals and provides a locally readable digital display, making it ideal for coating chambers, vacuum lines, and production gas manifolds.
