About performance
Efficient and energy-efficient: Designed with two-stage compression, our two-stage oil-free screw air compressors can more effectively utilize energy than a single-stage air compressor does. Under the same power input, more compressed air can be outputted and the operating cost is lowered accordingly.
Stable pressure: Our two-stage oil-free screw air compressors can output pressure steadily and continuously. Even under a high working load, the outputted pressure hardly fluctuates. This ensures the stability of the production process.About air quality
Oil-free and clean: Thanks to a special oil-free design, the compressed air contains no oil. In this way, the air purity can be guaranteed. For food processing, pharmaceutical, and electronics industries, etc. with strict air quality requirements, air purity is critical, and ensuring air purity can avoid product quality problems caused by oil contamination.
About reliability
High durability: Internal key components such as the screw are made from high-quality wear-resistant materials. Through precision machining and strict quality inspection, our products are highly durable. Therefore, the maintenance and replacement frequency of devices can be reduced.
Stable operation: The advanced two-stage screw technology result in little vibration and steady operation of air compressors during their running. This may lower the possibility of equipment failure caused by mechanical vibration.About maintenance
Simple and convenient maintenance: The reasonable overall structural design makes it convenient for daily maintenance. For example, routine maintenance procedures such as separator element replacement become simpler, faster, and more convenient, which may save time and human costs.

Application description
Rebar is the common name for hot rolled ribbed steel bars. The grade of ordinary hot-rolled steel bar is composed of HRB and the minimum yield point of the grade. H, R, and B are the first letters of the three words Hotrolled, Ribbed, and Bars respectively. Hot-rolled ribbed steel bars are divided into three grades: Grade II HRB335 (the old grade is 20MnSi), Grade III HRB400 (the old grades are 20MnSiV, 20MnSiNb, 20Mnti), and Grade IV HRB500.
