Frequently Asked Questions

Q What does ISO 8573-1 Class 0 oil-free certification mean for this compressor?

ISO 8573-1 Class 0 is the highest standard for compressed air purity, verifying that the discharged air contains zero detectable oil content. This magnetic levitation centrifugal compressor achieves this through a completely frictionless, oil-free mechanical design — no lubricants are used anywhere in the compression process, making it ideal for food, pharmaceutical, and electronics applications.

Q How does magnetic levitation technology improve compressor efficiency?

The rotor is suspended using electromagnetic force, eliminating all physical contact between rotating and stationary parts. This removes mechanical friction losses entirely, which allows the compressor to maintain high efficiency consistently over its full operational life without the performance degradation typical of conventional bearing-based compressors.

Q How much energy can be saved compared to traditional oil-free screw compressors?

These magnetic levitation centrifugal compressors achieve more than 30% energy savings compared with conventional oil-free screw compressors operating under equivalent conditions. The savings come from eliminating friction losses, using variable-speed control, and achieving higher overall isentropic efficiency — significantly reducing operating costs over the compressor's lifetime.

Q What remote monitoring and communication options are available?

The intelligent control system supports RS485, RS232, and Ethernet communication protocols, enabling seamless integration with existing plant automation and SCADA systems. Operators can monitor real-time performance data, set operational parameters, and carry out remote diagnostics or maintenance without requiring on-site access.

Q What is the noise level of this compressor, and why does it matter?

Operating noise is below 75 dB(A), which is at least 10 dB lower than conventional oil-free screw compressors that typically exceed 85 dB(A). Lower noise levels improve workplace safety and comfort, reduce the need for acoustic enclosures, and make installation in noise-sensitive environments — such as hospitals, laboratories, and food plants — far more practical.

Q Which model should I choose for my application, and what is the flow regulation range?

Models range from TMC 120 (120 kW) up to TMC 450 (450 kW), covering inlet flow rates from 33 m³/min to 170 m³/min across discharge pressures of 200–350 kPa. Flow regulation ranges vary by model from 50%–100% to 75%–100%, providing flexible capacity control.
