HIVAC F-4 High Vacuum Diffusion Pump Oil

Core feature

1. Ultra-high vacuum performance: The saturated vapor pressure is extremely low, and under normal operating conditions, it can stably achieve a vacuum degree of 10⁻⁷ to 10⁻⁸ Torr. When combined with the liquid nitrogen condensation valve, it can even reach an ultra-high vacuum standard of 10⁻¹⁰ Torr, meeting the requirements of precision manufacturing processes.

2. Exceptional environmental adaptability: Excellent resistance to oxidation, high temperature, and chemical corrosion. It will not undergo thermal rupture even at high temperatures and under vacuum conditions, and will not produce acids, tar, asphalt, or other impurities, thus avoiding contamination of the vacuum system.

3. Stable operation guarantee: As a non-petroleum and non-fatty acid ester type pump oil, it has stable chemical properties, no oxidation gas production phenomenon, and supports the long-term continuous operation of the vacuum pump, significantly reducing maintenance frequency.

4. Basic parameter specifications: The appearance is colorless and transparent liquid. At 25°C, the viscosity is 37 mm²/s and the specific gravity is 1.065. It has good fluidity and compatibility, and is compatible with mainstream diffusion pump models.

Applicable scenarios

Electronic/semiconductor field: Maintenance of vacuum environment for high-precision processes such as semiconductor wafer manufacturing and vacuum coating.

Research and experimentation field: Acquisition of ultra-high vacuum for experimental equipment such as electron microscopes, vacuum metallurgy, vacuum drying/distillation.

Precision manufacturing field: Assurance of vacuum conditions in the production of high-end products such as optical components and aerospace parts.

Product advantages

Safe and clean: No impurities are generated, preventing contamination of precision components and vacuum systems, meeting the requirements of high cleanliness production.

Long-lasting and durable: Outstanding thermal stability and chemical stability, with a service life far exceeding that of traditional oil pumps, reducing replacement costs.

Wide adaptability: Can directly replace Dow Corning DC704, compatible with various industrial-grade and research-grade oil diffusion pumps, without the need to adjust equipment parameters.
