In the field of industrial compressed air,
oil free scroll air compressors are preferred for clean scenes due to their “zero pollution and low energy consumption” characteristics. As a ZAKF
Screw Air Compressor manufacturer with 20 years of experience and 60,000 square meters of production base, our
oil free scroll compressor models support CE/ASME and other global certifications, with a monthly production capacity of up to 500 units, and 15-day shipping to Southeast Asia / Middle East based on 7 overseas warehouses. The following is an analysis of the value of oil-free scroll compressors and ZAKF's customization capability from technical advantages to industry applications.
I. Four core advantages of oil-free scroll compressor
1. 100% oil free cleanliness to meet the stringent environmental protection requirements
Scroll disk contactless design: the dynamic and static scroll disks adopt involute meshing, with a gap control of 0.02-0.05mm, so that there is no lubricant involved in the compression process, and the cleanliness of the gas reaches ISO 8573-1 Class 0, which is far superior to the Class 2 standard of the traditional oil-injected screw machine. ZAKF's 5-axis machining center achieves a scroll disk accuracy of ±0.003mm, ensuring long-term stability of oil-free performance.
Food-grade certification: Customized ASME-certified model for a bakery company in the U.S. with FDA food-grade coating to avoid oil contamination during the bread fermentation process, reducing maintenance cost by 40% compared with traditional models.
2. High efficiency and energy saving, dynamically matching the load demand
Volume efficiency up to 95%: the multi-stage compression chamber design of scroll disk (usually 6-8 pairs of compression chambers) makes the isothermal efficiency 20% higher than that of piston compressor, and the case study of an electronic factory shows that the ZAKF oil-less scroll machine (with a flow rate of 10m³/min) saves 120,000 kWh of electricity per year, with a payback period of 1.5 years.
Frequency control without loss: Adopting permanent magnet synchronous motor + vector control, the speed adjustment range is 30%-100%, and the efficiency only decreases by 3%-5% at small load, which is better than the 8%-10% fluctuation of screw machine. 3. Low noise and compact design.
3. Low noise and compact design
noise ≤ 65dB quiet advantage: scroll disk smooth engagement without impact, with ZAKF self-developed soundproof cover (thickness of soundproof cotton 50mm), the operating noise is 10-15dB lower than the screw machine, suitable for hospitals, laboratories and other quiet scenarios.
40% reduction of floor space: integrated design eliminates gear box and complex oil circuit. After adopting ZAKF model in a Japanese precision instrument factory, the floor space of the air compressor station has been reduced from 30 square meters to 18 square meters.
4. Maintenance-free and long life
Maintenance cost reduced by 70%: the lubricant-free system eliminates the need for oil change and filtration, and only requires annual replacement of the air filter element, and ZAKF's 20 years of material research and development has resulted in a wear-resistant coating on the scroll disk with a life of 80,000 hours (compared to 50,000 hours for a conventional screw rotor).
Intelligent diagnostic system: the standard PLC controller monitors the changes of the scroll disk gap in real time, and gives an automatic warning when the wear amount exceeds 0.01mm, which has been used by a German automobile factory to reduce unplanned downtime by 90%.
Five core industry applications and ZAKF customized solutions
