两级干式螺杆无油压缩机不仅以其精心的设计给人留下深刻印象，当然这些创新的细节都基于富诺尔的产品品质。

The two-stage dry screw oil-free compressor is not only impressive with its careful design, of course, these innovative details are based on the product quality of fu promise air.

无油的主机

Reliable host

在每一台富诺尔干式无油螺杆压缩机都装有一个久经考验的无油主机，提供最佳的性能和可靠性，每一个无油主机在其使用寿命内都保持很好的效率。

Each fu promise air dry oil-free screw compressor is equipped with a proven oil-free host to provide the best performance and reliability. Each oil-free host maintains good efficiency within its service life.

耐久的图层

Durable layer

使用特殊“超级图层”工艺对转子进行喷砂和磷化处理，以产生耐高温度高达300℃的创新和耐用图层。因为这个高性价比的图层具有很高的耐磨性，即使经过多年的操作，其密封和保护性能仍保持不变。

The rotor is sandblasted and Phosphated using a special "super layer" process to produce innovative and durable layers resistant to high temperatures up to 300 ℃. Because this cost-effective layer has high wear resistance, its sealing and protection performance remains unchanged even after years of operation.

铬干钢转子

Chromium dry steel rotor

二级压缩转子采用不锈钢材质，这消除了转子的生锈而引起的卡死或堵塞。

The secondary compression rotor is made of stainless steel, which eliminates the jamming or blockage caused by the rust of the rotor.

主机冷却

Main engine cooling

在真正需要冷却的点，冷却剂直接通过主机的外壳夹层，带走高温热量，以确保良好的散热，保持好的压缩频率。

At the point where cooling is really needed, the coolant directly passes through the shell interlayer of the host to take away high-temperature heat, so as to ensure good heat dissipation and maintain good compression frequency.
