Compressed air filters are used to remove contaminants from air after compression. There are many types, sizes and levels of quality for filters, depending on their use. Choosing the right type of filter depends on the level of maintenance you are willing to perform and the requirements of your system.
Finding the right filter for your industrial air compressor can increase the efficiency of your unit and reduce energy costs.

  • Why use a compressed air filter?

    ewo filter regulator

    High-precision industrial processes must be free of contaminants. Just as when you put a paper filter in your percolator to obtain a clean, perfectly filtered coffee, your pneumatic equipment (valve or cylinder) needs a compressed air filter to work with air that is free of particles, oil aerosols and other lubricants.

    Compressed air increases the concentration per m3 of particles in the atmosphere. Theair leaving a compressor is also loaded with other contaminants(灰尘,铁锈,油,水等)。

    In order to obtain the purest air quality possible,过滤器必须连接到气流以捕获杂质在他们污染系统之前。

    因此,安装正确的压缩空气过滤器将防止:

    • 损坏昂贵的设备(金属部件的腐蚀,阀门堵塞和管道等)
    • contaminating products (particularly in the agri-food, pharmaceutical and medical industries)
    • affecting the performance or lifetime of other air handling components
    • fires
    • 由于设备分解而导致的意外停机
    • constant equipment maintenance
  • How to choose a compressed air filter?

    Before choosing your compressed air filter, there are several elements you should consider:

    • 待过滤颗粒的大小
      • There are standard universal filters that remove particles from 5 to 40 microns.
      • 除了小于1微米的颗粒也存在除粒子的过滤器,特别是制药和食品工业设备。
    • 流速和头部损失(or pressure drop)
      • 根据要管理的流量,过滤器以不同的尺寸存在。这些流量可高达1,700nm³/ h。
      • In order to select the right size, you will need to determine the maximum head loss for your filter.
      • 根据制造商提供的流速,请参阅压降曲线。
      • 为最佳操作,建议避免压降大于5 psi。
    • 温度
      • 您的压缩空气过滤器在什么温度下运行?
      • High performance filters are available for high temperatures (over 450°C).
    • Environmental standards
      • Compressed air filters are subject to the ISO 8573 standard, which specifies the purity classes of compressed air for the presence of solid particles, water and oil, regardless of their location in the compressed air system.
      • 本标准还提供了关于压缩空气系统中污染物的一般信息,并指的是ISO 8573的其他部分关于压缩空气纯度的测量或压缩空气纯度要求的规格。
      • Lastly, the ISO 8573-1:2010 standard also identifies gaseous and microbiological pollutants.

    Elements to consider before choosing your filter:

    • 待过滤颗粒的大小
    • 流速和头部损失
    • 温度
    • 适用的标准
  • What are the different types of compressed air filters?

    皮脂粒子过滤器

    There are various filters available for removing different types of contaminants.

    粒子过滤器

    They remove particles such as dust, dirt, pollen, etc.

    They remove 99% of the particles present in the air with a diameter of 0.3 micrometers.

    Coalescing filter

    它们用于过滤液体,油气和某些亚微米颗粒(最多0.01微米)悬浮在压缩空气中。

    他们增加了coalescence of liquids。聚结是过程中液体熔化在一起的细滴,以在压降的作用下形成大滴。随着液滴生长,它们落入水分疏水阀,脱离任何液体污染物的空气。这意味着获得的压缩空气是干燥器和更清洁的。

    他们是easy to maintain因为它们没有多大堵塞,但这些过滤器是not effective at removing vapours

    There are also cold coalescing filters (operating at 2°C) that are more effective at filtering moisture.

    JURA FILTRATION activated carbon filter

    • Activated carbon或蒸汽过滤器
      • 它们用于通过称为“吸附”的过程消除气味和杂质。
      • Adsorption is the chemical process by which the activated carbon filter naturally attracts oil vapors.
      • These filters are very expensive however.
      • 它们还需要防尘过滤器以防止小煤颗粒爆裂并进入气流。
  • Why choose a pressure regulating filter?

    CAMOZZI AUTOMATION filter regulator

    Pressure regulating filters provide clean, dry air with controlled pressure.

    • They can be mounted in a compressor, or between compressed air lines, in addition to the compressed air devices.
    • The pressure can be adjusted manually at any time. This means you don’t have to worry about pressure fluctuations. You will be able to keep full control over the pressure thanks to a pressure gauge, supplied with the pressure regulating filter.
  • Why choose a filter lubricator?

    A filter lubricator is a component that cleans the air from the compressor and lubricates it for the network.

    • Lubrication is made possible by an integrated lubricator that controlls the quantites of oil added to the compressed air system.
    • Filter lubricators are compact, easy to install and inexpensive.
    • 他们是, most often, equipped with a tank of about 150ml. This will allow you to avoid using traditional lubrication methods, which are very time-consuming.
    • This will help you avoid damage to your pneumatic equipment, which can be caused by moisture, rust or limescale.
