SFF–Series: SEMI Standard Gas Mass Flow Controllers
Drop-in replacement for vacuum coating systems—FastTrack means we ship to you, customized, in just 5 days.
SFF-Series SEMI Standard Gas Mass Flow Controllers are manufactured with 1/4″ VCR®-compatible male fittings machined right into the flowbody to eliminate leaks from welded fittings. The device matches end-to-end with SEMI standard MFCs, for easy drop-in upgrades to vacuum deposition fixtures. Control mass flow or pressure of 98 gases.
- Drop-in compatibility. Form factor includes machined in place 1/4″ VCR®-compatible male fittings and matches 124 mm end-to-end length of SEMI standard MFCs.
- Versatile & accurate. Real-time control with NIST-traceable accuracy up to ±(0.4% of reading + 0.2% of full scale) for on-board 98 gas calibrations and 20 custom-defined mixtures you can build yourself.
- Easy integration. Custom process ports and electrical connectors, and your choice of EtherNet/IP, EtherCAT, DeviceNet, PROFIBUS, PROFINET, Modbus (RTU and TCP/IP), or serial communications for easy integration into your industrial process.

Device Features
Included with each device
- Multi-variable process measurements: Simultaneously measure mass flow, volumetric flow, gas pressure, and gas temperature.
- User changeable units of measurement: Change the unit of measurement for pressure, flow, or temperature from our extensive list of engineering units.
- Gas selectability: Select your process gas from any of the 98 preloaded NIST-traceable gas calibrations in our gas list.
- Gas Select COMPOSER™: Define 20 custom gas mixtures of up to 5 constituent gases using our Gas Select Composer™ firmware.
- Monochrome backlit LCD with integrated touchpad: Easily read measurements using the backlit display and control configurations with the user-friendly integrated touchpad.
- User adjustable setpoint ramping & limits: Configurable ramp rates allow the process variable to be controlled as fast or as slow as desired, and configurable setpoint limits protect processes from inadvertent setpoint changes.
- User adjustable standard temperature and pressure (STP) conditions: Quickly change reference conditions without need for recalibration.
- Valve close override and valve open override: Utilize alarms to quickly vent your system or stop all flow as needed.
