1. Adopt large rotor and low speed to ensure high performance of the machine;
2. Increase the oil and gas separation equipment to ensure that the oil content at the outlet is less than or equal to 2ppm;
3. The air source of the low-pressure screw air compressor is clean, which reduces the number of cleaning nozzles of the texturing machine and other equipment, and improves the quality of the finished product;
4. The heat dissipation area of the oil cooler is increased by more than 30% to ensure normal operation in summer without overheating;
5. Independently design the internal pressure ratio of the host to ensure better specific power;
6. The intelligent control system automatically adjusts the exhaust volume according to the customer's usage (frequency conversion model).
