Frequently Asked Questions
What does ISO 8573-1 Class 0 oil-free certification mean for compressed air quality?
ISO 8573-1 Class 0 is the highest standard for oil-free compressed air, certifying that the air contains zero detectable oil content in any form—liquid, aerosol, or vapor. This makes the TMC series centrifugal air compressors ideal for sensitive industries such as food processing, pharmaceuticals, and electronics manufacturing where contamination-free air is critical.
How does magnetic levitation technology contribute to energy savings?
Magnetic levitation eliminates all mechanical contact between the rotor and its housing by using electromagnetic force to keep the rotor suspended. This removes friction loss entirely, which is a major source of energy waste in conventional compressors. Combined with variable-speed operation, the TMC series achieves more than 30% energy savings compared to traditional oil-free screw compressors.
What communication protocols does the intelligent control system support?
The TMC series supports RS485, RS232, and Ethernet communication protocols. This multi-protocol compatibility enables seamless integration with existing plant control systems, allowing operators to perform real-time monitoring of operating parameters and carry out remote diagnostics or maintenance without requiring on-site intervention.
How quiet is the TMC series compared to conventional oil-free screw compressors?
The TMC series operates at noise levels below 75 dB(A), which is significantly quieter than conventional oil-free screw compressors that typically exceed 85 dB(A). This 10+ dB(A) reduction results in a noticeably quieter working environment, reduces the need for soundproofing enclosures, and helps meet workplace noise regulations.
Which model should I choose based on my required flow rate and discharge pressure?
Model selection depends on your required inlet flow rate (m³/min) and discharge pressure (kPa). For example, if you need approximately 90 m³/min at 250 kPa, the TMC 300 would be appropriate. The TMC series ranges from TMC 120 (120 kW, up to 43 m³/min) to TMC 450 (450 kW, up to 170 m³/min). Please refer to the Technical Parameter table above or contact our technical team for a precise recommendation.
Is the TMC series suitable for use in the food and pharmaceutical industries?
Yes, the TMC series is highly suitable for food and pharmaceutical applications. Its ISO 8573-1 Class 0 certification guarantees completely oil-free compressed air, which is essential for direct contact applications such as filling, packaging, fermentation, and spraying. The oil-free design also eliminates the risk of product contamination, helping manufacturers comply with strict hygiene and safety regulations.
