MODEL 5100 SERIES - The high-grade metal sealed mass flow controller products
The KOFLOC High-Grade Metal Sealed Mass Flow Controller MODEL 5100 SERIES is the top-of-the-line mass flow controller and is the successor to the well-received 3440 SERIES. It is designed as the top-performing industrial-grade gas mass flow controller, with focus on low zero-drift, low range response and good control.

KOFLOC MFC MODEL 5100 SERIES
Quick Review
•Improved Response & Control
The KOFLOC High-Grade Metal Sealed Mass Flow Controller MODEL 5100 SERIES has improved control/response at all ranges over previous models and improved proportionality to control voltage. It is also equipped with range switching function for multi-range applications. Additional control resolution can be obtained through valve optimization.
•Clean-Room Production
A class 100 clean-room production is available for the KOFLOC High-Grade Metal Sealed Mass Flow Controller MODEL 5100 SERIES, if specified, for applications requiring extra cleanness such as CVD (Chemical Vapor Deposition) and other semiconductor processes.
• KOFLOC Dependability
KOFLOC has 60 years of experience in manufacturing precision flow instruments. KOFLOC products, both standard and off-catalog custom items are well received throughout Japan as the name that manifests confidence. KOFLOC, the fluid expert, is the name professionals trust in precision control of minute flow.
• High Temperature Models
The KOFLOC High-Grade Metal Sealed Mass Flow Controller MODEL 5100 SERIES has a standard high temperature option especially suited for processes of baking, that can withstand temperature up to 80˚C.
• Diaphragm Valve
The KOFLOC High-Grade Metal Sealed Mass Flow Controller MODEL 5100 SERIES utilizes the unidirectional normally closed valve with higher dependability and safety. This valve also reduces internal dead-space.
• Standardized Dimensions and Parts
The KOFLOC High-Grade Metal Sealed Mass Flow Controller MODEL 5100 SERIES retains the standard 3 in (76 mm) footprint, regular fittings and SEMI standard serial connector to easily replace and fit into existing gas lines without any modifications for use in widest possible applications.
• Low Zero Drift
The KOFLOC High-Grade Metal Sealed Mass Flow Controller MODEL 5100 SERIES looks like any other mass flow controller but it employs the new improved sensor-drive mechanism, improving on the well-regarded zero-drift performance of MODEL 3440 SERIES.
• Adaptability
The KOFLOC High-Grade Metal Sealed Mass Flow Controller MODEL 5100 SERIES is in wide use as a component CVD, sputter deposition, bond wiring and welding for semiconductor and electronic industries. The MODEL 3200 is also used as a general-purpose mass flow controller in industrial applications of exhaust sampling, including gas mixing, air sampling, burn control and more.
