    HEPA filter for 3D printer
    Custom HEPA filter for 3D printer

    You may need a HEPA filter that can filter fine dust if you are using a 3D printer.

    3D printers will produce fine particles and VOC emissions during operation. Some 3D printers on the market have a closed body and have a purification system inside, which can filter out these emissions; but some open 3D printers do not have the HEPA filter system, the smoke will be discharged into the room, which is harmful to the human body.

    PLA produces more toxic particles than ABS, but PLA does not produce more pollution than ABS. Both will produce odor, even if there is no smell, it does not mean that no toxic gas is produced, usually, some are colorless and odorless. Here, it is recommended to use the combination of a custom HEPA filter + carbon filter.

    HEPA filtration grade is H13, which can filter 99.9% of particles larger than 0.3 microns, while most of the particles released by 3D printers are larger than 0.3 microns, so HEPA has a very good performance on purifying this emission.

    Activated carbon particles have a very good performance on the adsorption of odors and toxic and harmful gases. It can be used in combination with HEPA filters to remove harmful gas, VOC and so on.

    Provide customized size and efficiency according to customer’s design requirements.

      HEPA filter helps fix industry pollution
      Air filters improve air pollution caused by industry

      We long for fresh air without any pollution. We enjoy the gift of nature and take a deep breath. However, industrial pollution has brought air pollution, a large amount of PM2.5 and other pollutants such as formaldehyde, toluene, sulfur dioxide, nitrogen dioxide in the air. It seriously affects human breathing and brings disease and pain.
      Maybe we can’t immediately improve air pollution across the planet, but we can improve air pollution in our own homes.

      Air filters for pharmaceutical applications
      Pharmaceutical cleanroom air filters and equipment

      In order to keep the pharmaceuticla cleanroom cleanliness level, the air filters and equipments are necessary.

      There are some basic air filters should be applied.

      1. HEPA filters —– to remove particle over 0.3 micron, efficiency H13 or H14 EN:1822
      2. V bank filter or pocket air filter — to remove particle size over 5 micron, efficiency F7, F8, F9 and so on. this filter can enlarge HEPA filter service life.
      3. Pre air filter —- remove large dust so that enlarge service life for HEPA, v bank or pocket air filter.

      The air filter of a pharmaceutical factory is a vital product to maintain the cleanliness of its cleanroom. Without an air filter, the clean room will not exist.

      Depending on the product line, different purification plants need to be designed and require different levels of cleanliness. This affects which air filter and HEPA filter specification and quantity.

      In pharmaceutical plants, the most rigorous formulation workshops require Gel Seal HEPA filter, which are rated ISO5 class 100. In order to maintain cleanliness, the number of air changes per hour needs to be 60-200 times.

      Efficient air supply or FFU can be installed on the top of the pharmaceutical workshop. This depends on the cleanliness level. If it is a demanding preparation workshop, FFU is required. If it is a general workshop, you can use a HEPA filter ceiling module.

      Air showers and pass box are recommended to prevent staff from entering or exiting or entering and leaving the facility with additional sources of contamination. This is the necessary equipment for the pharmaceutical factory.

      Some specific sites require high-temperature resistant HEPA filters, such as high-temperature filters resistant to 350-400 degrees, which are commonly used in high-temperature sterilization channels in pharmaceutical plants.
