FU独特的分离过滤器是旋风分离与过滤两个功能的组合产品,具有节省安装空间,减轻滤芯负荷的优点。旋风分离组件可以去除大部分的液态油水及大的固体颗粒，滤芯再进一步除油除尘，分离器滤芯一般选用P级或M级。产品可以安装在紧凑空间的机器内部，冷冻式干燥机前，空分设备后以及其他应用场合。

The unique advantage of the combination of two cyclone filter elements is that they can reduce the installation space and reduce the load of the two cyclone filters. The cyclone separation module can remove most of the liquid oil-water and large solid particles, and the filter element can further remove oil and dust. The filter element of the separator generally adopts grade P or m. The product can be installed inside the machine in a compact space, in front of the freeze dryer, behind the air separation equipment and other applications.

压缩空气过滤器的工作原理

Working principle of compressed air filter

大气中含有水蒸气，碳氢化合物及固体颗粒(每立方米的空气中含有大约1亿4千万个固体颗粒)，这些杂质随着空气被吸入空压机中，然后和残留的润滑油一起进入压缩空气管网。这些污染物如果不能及时得到处理将会导致管道腐蚀，危害到生产设备及工具的灵敏度和寿命，并对制造产品的质量造成影响。

The atmosphere contains water vapor, hydrocarbons and solid particles (about 140 million solid particles per cubic meter of air). These impurities are sucked into the air compressor with the air, and then enter the compressed air pipe network together with the residual lubricating oil. If these pollutants cannot be treated in time, they will lead to pipeline corrosion, endanger the sensitivity and service life of production equipment and tools, and affect the quality of manufactured products.

当待处理的压缩空气进入过滤器时，流速放缓，大颗粒的液滴在重力作用下掉落下来，还有一些液滴和固体颗粒在通过玻纤滤料层时被直接拦截下来。较小直径的液滴和固体颗粒随气流通过滤芯时，因惯性碰撞被滤料捕捉并逐渐凝聚成更大的液滴流下来，更小的固体和液体颗粒不随气流改变方向，只是在做布朗运动，一旦接近滤料时，受玻纤的静电引力影响而被吸附在滤料上。过滤出来的油水聚集在过滤器的底部，经排水器排出。为了保护环境，排出的油水必须要有专门的容器收集，切勿直接排放到公共污水管。

When the compressed air to be treated enters the filter, the flow rate slows down, the droplets of large particles fall down under the action of gravity, and some droplets and solid particles are directly intercepted when passing through the glass fiber filter material layer. When the smaller diameter droplets and solid particles pass through the filter element with the air flow, they are captured by the filter material due to inertial collision and gradually condensed into larger droplets. The smaller solid and liquid particles do not change the direction with the air flow, but only do Brownian motion. Once they approach the filter material, they are adsorbed on the filter material under the influence of the electrostatic attraction of glass fiber. The filtered oil and water is collected at the bottom of the filter and discharged through the drain. In order to protect the environment, the discharged oil and water must be collected in a special container and must not be directly discharged to the public sewage pipe.
