Frequently Asked Questions
ISO 8573-1 Class 0 is the highest level of oil-free air quality certification. It means the compressed air output contains zero detectable oil content in any form — liquid, aerosol, or vapor — making it suitable for the most demanding applications such as food processing, pharmaceuticals, and electronics manufacturing.
Magnetic levitation (maglev) technology uses electromagnetic force to suspend the rotor completely, eliminating all mechanical contact and friction between moving parts. This means no energy is lost to friction, no lubricating oil is required, and efficiency remains consistently high throughout the compressor's operational lifespan.
The magnetic levitation centrifugal blower achieves more than 30% energy savings compared to conventional oil-free screw compressors. This significant reduction in power consumption translates directly into lower operating costs and a faster return on investment, especially in high-usage industrial environments.
The intelligent control system supports RS485, RS232, and Ethernet communication protocols. This multi-protocol compatibility enables seamless integration with existing industrial automation systems, SCADA platforms, and remote monitoring infrastructure, allowing operators to perform real-time monitoring and remote maintenance from any location.
These blowers operate at noise levels below 75 dB(A), which is significantly quieter than conventional oil-free screw compressors that typically exceed 85 dB(A). The lower noise level improves workplace safety, reduces the need for soundproofing infrastructure, and creates a more comfortable working environment for operators.
Model selection depends on your required discharge pressure (200–350 kPa) and inlet flow rate. For example, if you need approximately 75 m³/min at 250 kPa, the CXF 220 model would be appropriate. Please refer to the Technical Parameter table above for a full comparison of all models (CXF 120 through CXF 450) across different pressure and flow configurations. Our technical team can also assist with custom application matching.
