In the field of industrial vacuum applications,
oil free vacuum pumps have become a necessity for precision industries such as semiconductor and pharmaceutical industries due to their “zero pollution and low maintenance” characteristics. As a ZAKF
Screw Air Compressor manufacturer with 20 years of experience and 60,000 square meters of production base, our oil free vacuum pumps support CE/ASME and other global certifications and customization, with a monthly production capacity of up to 500 units, and relying on 7 overseas warehouses to achieve 15 days of speedy delivery in Southeast Asia / Middle East. Below is the analysis of the core value of oil-free
vacuum pumps and ZAKF's customization ability from technical advantages to industry applications.
Five core advantages of oil free vacuum pumps
1. 100% oil-free cleanliness to meet the stringent environmental standards
Oil-free compression chamber design: ZAKF oil-free vacuum pumps adopt dry screw, scroll or claw rotor structure, no lubricant is involved in the compression process, and the gas cleanliness is up to ISO 8573-1 Class 0, which is far superior to the Class 3 standard of traditional oil-lubricated vacuum pumps. For example, the ASME-approved model customized for a US pharmaceutical factory has passed the FDA food-grade coating treatment, avoiding the risk of oil contamination in pharmaceutical production.
Precision processing guarantee: 60,000 square meters production base is equipped with German five-axis machining center, rotor precision control at ±0.003mm, to ensure the long-term stability of the oil-free performance, a Korean semiconductor factory case, the equipment for three consecutive years of operation of the oil content of the gas source <0.01mg/m³.
2. Energy-efficient and low-power operation
Volumetric efficiency upgraded to 92%: The multi-stage compression chamber design of ZAKF scroll oil-free vacuum pump makes the isothermal efficiency 18% higher than that of traditional piston pumps, and the application case of a Taiwan LCD factory shows that the model with a flow rate of 150m³/h saves 80,000 kWh of electricity annually, with a payback period of 1.3 years.
Intelligent frequency conversion control: adopting permanent magnet synchronous motor + vector control, the speed adjustment range is 30%-100%, the efficiency only decreases by 3%-5% at small load, with ZAKF self-developed energy-saving algorithm, the energy saving is 25%-30% compared with the fixed-frequency pump.
3. Low Noise and Compact Design
Quietness Advantage with Noise ≤68dB: ZAKF claw-type oil-free vacuum pumps have a smooth meshing of double claw rotors, and with a 50mm thickness soundproof cover, the operation noise is 12-15dB lower than traditional oil pumps, suitable for laboratories, hospitals and other quiet scenes.
35% reduction in floor space: integrated design eliminates the complex oil circuit system. After adopting ZAKF model in a Japanese precision instrument factory, the area of the vacuum station has been reduced from 25m2 to 16m2, which increases the space utilization rate by nearly 40%.
4. Maintenance-free and long life cycle
Maintenance cost is reduced by 60%: the lubricant-free system eliminates the process of oil change and filtration, and only needs to replace the air filter element every year. ZAKF has made the rotor wear-resistant coating life up to 80,000 hours (the life of the traditional oil-type pump is 50,000 hours) through the material research and development for 20 years.
Intelligent diagnostic system: standard PLC controller monitors the rotor gap changes in real time, and automatically warns when the wear amount exceeds 0.01mm, which has been used by a German automobile factory to reduce unplanned downtime by 85%.
5. Wide working condition adaptability and certification compatibility
All-scene adaptability: ZAKF oil-free vacuum pump supports -20℃~+50℃ environment operation, and is equipped with moisture-proof plus heat tape as standard for high humidity areas (e.g., Southeast Asia), and the desert model is equipped with an automatic dust remover, which has reduced the failure rate by 70% after application in a photovoltaic project in the United Arab Emirates.
Global certification support: Provide 20+ international certifications such as CE, ASME, ATEX, etc. For example, the explosion-proof model developed for the chemical industry in Europe has passed the ATEX 2014/34/EU certification, and can be used for vacuuming of flammable and explosive gases.
