Frequently Asked Questions

Q: What are the main energy-saving benefits of the Two-Stage Compression system?
A: The integrated two-stage compression system optimizes the internal oil and gas channels. By compressing the air in two distinct stages, it improves thermodynamic efficiency, resulting in up to 15% energy savings compared to standard single-stage compression models.
Q: How does the Permanent Magnet Motor contribute to operational efficiency?
A: The high-efficiency permanent magnet motor prevents energy loss during periods of no-load operation. It supports a wide speed regulation range, leading to an extra 6%-7% energy savings compared to conventional three-phase asynchronous motors.
Q: Can the supply voltage and frequency be customized for different regions?
A: Yes, while the standard configuration operates on 380V, 3-Phase, 50Hz, alternative voltages and frequencies can be fully customized according to your regional industrial power specifications.
Q: What role does vector control play in the VSD frequency conversion?
A: High-performance vector control in the inverter minimizes mechanical friction losses and matches output precisely to real-time air demand. This intelligent regulation can save up to 42% energy compared to fixed-speed industrial air compressors.
Q: What is the typical oil content and temperature limit for output air?
A: The output air is highly purified, maintaining an oil content of ≤ 3 PPM. Additionally, the air supply temperature is exceptionally controlled, remaining at ≤ ambient temperature +8~15°C to protect downstream equipment.
Q: How does the cooling system maintain low noise levels?
A: The machine utilizes large-diameter, low-speed axial flow fans. This specialized configuration lowers the overall operating noise profile while decreasing power usage compared to standard high-speed cooling fans.
