Gas Flow Control Solution – MKS Instruments MKS 1579A00412LM1BV | 1579A Series
Where This Product Is Used
The MKS 1579A00412LM1BV Digital Mass Flow Controller is engineered for precision gas flow management in demanding industrial and semiconductor environments. Typical deployment scenarios include:
- Semiconductor Fabrication (CVD / PECVD / ALD) – Precise precursor gas delivery to deposition chambers where flow accuracy directly impacts film uniformity and yield.
- Etch Process Tools – Stable, repeatable flow of reactive gases (Cl₂, HBr, SF₆) in plasma etch systems requiring tight process windows.
- Gas Blending & Mixing Panels – Multi-channel manifold systems where each MFC must maintain independent set-point accuracy across varying upstream pressures.
- R&D Laboratories & Pilot Lines – Benchtop gas delivery rigs for process development, where digital communication (RS-485 / analog 0–5 V) simplifies data logging.
- Industrial Process Control – Specialty gas dosing in chemical synthesis, fuel cell testing, and environmental monitoring instrumentation.

Why Engineers Specify This Model
- Digital Stability – Onboard microprocessor compensates for temperature drift, delivering consistent accuracy across ambient swings common in fab environments.
- Drop-in Compatibility – Standard 1.125″ face-seal (VCR / W-seal) port configuration matches existing MKS 1179 / 1259 footprints for straightforward upgrades.
- Dual-Mode Communication – Supports both analog set-point and RS-485 digital protocol, enabling integration with legacy PLC systems and modern SCADA/DCS platforms simultaneously.
- Fast Set-Point Response – Sub-2-second settling time minimizes recipe transition delays in multi-step deposition processes.
- Long Service Life – Hermetically sealed sensor element and corrosion-resistant wetted path reduce maintenance intervals in corrosive-gas applications.

Application-Specific FAQ
Q: What gas is this unit calibrated for?
A: The calibration gas and full-scale range are encoded in the model number suffix. The “LM1BV” suffix indicates specific gas and range parameters — contact us with your process gas to confirm compatibility or request recalibration.
Q: Is this compatible with MKS PR4000 controllers?
A: Yes. The 1579A series uses the standard MKS 15-pin D-sub interface and analog 0–5 V signal, fully compatible with PR4000B/F and similar multi-channel readouts.
Q: Can it control corrosive gases like HCl or Cl₂?
A: The 316L SS wetted path and Viton seals provide good resistance to many corrosive gases. Confirm seal compatibility with your specific gas before deployment in aggressive chemistries.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock items typically have a 2–6 week lead time. Contact us for real-time availability.
Q: Do you provide a warranty?
A: Yes — 90-day functional warranty on all units. Extended warranty options available on request.
