In high-end manufacturing and precision processes, the quality of the vacuum environment directly determines the final performance and yield of the product. Single-stage oil-free screw vacuum pumps, with their revolutionary oil-free screw compression technology and comprehensive performance advantages, are gradually replacing traditional oil-lubricated vacuum equipment and becoming the core choice for critical processes in industries such as semiconductors, new energy, and food and pharmaceuticals. We offer more than just a
Vacuum Pump; we systematically address the underlying pain points of clean production, energy efficiency management, and sustainable operations.
I. Deep Technical Architecture and Core Value Breakthroughs
Complete Cleanliness, Eliminating Contamination from a Mechanistic Perspective
High-precision screw rotors and aerodynamic profiles achieve contactless engagement and completely dry compression, fundamentally eliminating contamination of process gases and the vacuum chamber by oil vapor, oil mist, or oil particles. Output gas purity exceeds 99.9%, meeting the most stringent cleanliness standards.
Redesigning Energy Efficiency to Promote the Transition to Low-Carbon Production
With a volumetric efficiency exceeding 85%, it consumes 20%-30% less energy than traditional liquid ring and oil-filled rotary vane pumps. Under the dual-carbon policy, this system helps companies significantly reduce electricity consumption during continuous production while also reducing embodied carbon emissions from oil consumption and disposal.
High reliability and low-maintenance design reshape equipment management logic.
The non-contact operation mode eliminates wear on major moving parts, resulting in a mean time between failures (MTBF) exceeding 20,000 hours. Requiring only regular replacement of the air intake filter, this significantly reduces spare part costs, maintenance labor, and downtime, making it particularly suitable for high-load industrial scenarios requiring continuous production.
Stable wide pressure range provides flexible system integration.
A single stage achieves stable pumping speeds over a wide range of 10 Pa to 1000 hPa, supports direct start-up at atmospheric pressure, eliminates the need for a backing pump, simplifies vacuum system architecture, and improves process response speed and overall reliability.
In semiconductor and integrated circuit processes such as wafer adsorption, PVD/CVD, and ion implantation, even the slightest oil contamination can render an entire batch of wafers useless. Oil vapor backflow in conventional pumps severely hinders yield improvement. Oil-free screw vacuum pumps provide an absolutely oil-free vacuum environment, eliminating hydrocarbon contamination, significantly improving film quality and device performance, and ensuring the stability and yield of advanced manufacturing processes.
In food and pharmaceutical packaging, oil contamination during high-speed vacuum packaging and aseptic filling can lead to product spoilage, mold, or excessive microbial growth, violating FDA and GMP regulations, leading to product recalls and brand risks. Oil-free screw vacuum pumps offer an oil-free design that meets food and pharmaceutical hygiene standards, ensuring a sterile and contamination-free packaging process, protecting consumer safety, and helping companies pass stringent compliance audits.
The emergence and widespread adoption of single-stage oil-free screw vacuum pumps reflects modern industry's redefinition of "clean vacuum" as a fundamental element of production. Through fundamental technological innovation, they systematically address the multiple challenges of high-end manufacturing in terms of quality control, energy consumption, equipment reliability, and environmental compliance. They have become a core infrastructure for companies building green production lines and achieving intelligent manufacturing upgrades.
On the road towards Industry 4.0 and sustainable development, choosing oil-free screw technology is not only an optimization of process solutions, but also a strategic decision for enterprises to improve product grades, reduce overall operating costs, and strengthen industry competitiveness.
