As a highly clean vacuum generator based on the screw compression principle, the single-stage oil-free
Screw Vacuum Pump achieves efficient gas compression and delivery through two precisely meshed counter-rotating screws, completely eliminating traditional oil lubrication and fundamentally eliminating oil contamination. It has become a critical infrastructure in many high-end manufacturing and scientific research scenarios. Its technical characteristics are highly aligned with industry needs. The following is an in-depth analysis of its performance advantages and industry applications.
1. Core Technology Advantages and Value Insights
Absolutely Clean Output Air Quality
The oil-free design completely eliminates oil vapor backflow and particulate release, achieving gas purity exceeding 99.9%. This not only protects process media from contamination but also significantly reduces back-end filtration and exhaust gas treatment costs, making it particularly suitable for sensitive materials and high-purity environments.
Energy Savings and Economic Operation
With a volumetric efficiency exceeding 85%, combined with optimized profile design and gap control, energy consumption is reduced by 20%-30% compared to traditional oil-lubricated vacuum pumps. In continuous operation, this difference translates into significant electricity cost savings, aligning with the trend toward low-carbon manufacturing.
High Reliability and Low-Maintenance Architecture
The non-contact screw rotor design significantly reduces mechanical wear, resulting in a mean time between failures (MTBF) exceeding 20,000 hours. Requiring only periodic air inlet filter replacement, the long maintenance cycle and simple operation effectively reduce downtime and labor costs.
Wide Operating Pressure Compatibility
It operates stably within a range of 10Pa to 1000hPa and supports direct startup from atmospheric pressure, eliminating the need for a pre-assisted pump. This flexibility enables it to adapt to complex and changing operating conditions and multi-stage vacuum process requirements.
II. In-Depth Analysis of Industry Applications
1. In the semiconductor manufacturing industry, wafer bonding, laminating, and PVD/CVD pre-processing processes can cause film contamination and device failure even with trace amounts of oil vapor, placing extremely stringent demands on vacuum cleanliness and stability. Our oil-free screw vacuum pumps operate oil-free, eliminating hydrocarbon contamination, maintaining a high-purity vacuum environment, and ensuring product yield and equipment life. 2. Beyond semiconductors, emerging industries such as battery module packaging for new energy vehicles and motor impregnation insulation processes are also facing challenges. Common battery electrolytes are sensitive, and oil contamination can easily cause short circuits or performance degradation. Motor processes require the elimination of bubbles and contamination. Our oil-free screw vacuum pumps provide a clean vacuum degassing environment, enhancing material permeability and insulation strength while avoiding the introduction of new contaminants.
Single-stage oil-free screw vacuum pumps not only represent technological advancements in vacuum generation but also reflect the clear trend in high-end manufacturing toward clean production, high efficiency, reliability, and intelligent operations and maintenance. Their extensive application across multiple key industries reflects the increasing quality requirements of the vacuum environment—the fundamental process element—in the current industrial system. By fundamentally addressing long-standing industry pain points such as oil contamination, high energy consumption, and frequent maintenance, this equipment has become a crucial technical support for driving industrial upgrading and achieving sustainable development. In the future, with the continued development of new materials, precision manufacturing, and biotechnology, the application boundaries of oil-free vacuum technology will continue to expand.
