What Is Fomblin® Y LVAC 06/6?
Fomblin® Y LVAC 06/6 is a low-viscosity perfluoropolyether (PFPE) fluid designed for lubricating and sealing compatible vacuum pumps. It combines low vapor pressure, chemical inertness, non-flammability and good low-temperature flow, making it suitable for vacuum systems where conventional hydrocarbon oils may degrade, oxidize or introduce process contamination.
Key Features and Process Benefits of Fomblin® Y LVAC 06/6
| Key feature | Process and customer benefit |
|---|---|
| Low vapor pressure | Helps reduce lubricant evaporation and backstreaming into the vacuum chamber. |
| Low-viscosity PFPE fluid | Supports easier circulation, lower starting resistance and efficient lubrication in compatible pump designs. |

Common Applications of Fomblin® Y LVAC 06/6
Mechanical and rotary vacuum pumps
Fomblin® Y LVAC 06/6 is primarily used as a sealing and lubricating fluid in compatible mechanical vacuum pumps. Its relatively low viscosity may be beneficial in pumps requiring rapid oil circulation, lower starting resistance or effective operation at reduced ambient temperatures. Syensqo describes the Y LVAC range as sealing and working fluids for vacuum pumps, including equipment handling aggressive gases.
Semiconductor and electronics production
Vacuum pumps used in semiconductor and electronics manufacturing may encounter corrosive gases and strict contamination limits. Y LVAC 06/6 can help reduce hydrocarbon backstreaming while resisting chemical degradation in properly designed and qualified systems.
Potential processes include plasma treatment, vacuum deposition, etching, electronic-component manufacturing and process-chamber evacuation. Suitability must be confirmed for the specific equipment and process chemistry.
Chemical-processing vacuum systems
The product can be considered for vacuum pumps exposed to acids, halogens, oxidizers and other aggressive chemicals that may rapidly degrade conventional mineral or synthetic hydrocarbon oils. Fomblin® PFPE fluids are documented as resistant to a broad range of aggressive gases and chemical agents.
Oxygen and oxidizing-gas systems
PFPE fluids are non-flammable and inert to liquid and gaseous oxygen, making them candidates for approved oxygen and oxidizing-gas systems. However, using PFPE fluid alone does not make a pump suitable for oxygen service. The equipment must be oxygen-clean, correctly configured and approved for the relevant pressure, temperature and oxygen concentration.
Clean and contamination-sensitive vacuum equipment
The low vapor pressure and absence of hydrocarbon base oil make Y LVAC 06/6 suitable for compatible systems where oil-vapor contamination must be controlled. Examples may include laboratory vacuum equipment, analytical instruments, optical processing and high-technology manufacturing.
Vacuum pumps operating at lower temperatures
With a typical pour point of −50°C, Y LVAC 06/6 offers better low-temperature flow than the higher-viscosity Y LVAC grades. This can be useful where cold start-up, low ambient temperature or rapid fluid circulation is important.
