Filter media for dust collectors
Dust collection systems are an important part of any manufacturing process, so they need to be sized and designed properly. One critical design component is specifying the proper filtration media, which requires analysis of the dust in the process and all operating conditions.
Your dust collector is only as strong as its filter cartridges, which makes filter selection vital. Filter elements need to use the type of media that is appropriate for your specific application and dust. For example, your application may require media treated with coatings that promote dust release, flame retardance or conductivity.
Using the wrong media can put workers at risk or cause high pressure drop and energy costs. Inefficient filtration also can lead to dust deposits creating a risk in event of an explosion. Using the correct media creates a safer, cleaner work environment with less dust collector maintenance.
Five factors you should take into consideration about your dust and process:
Cellulose/Paper and Spunbond/Synthetic are the two basic filter media types most commonly used for our filter elements.
The base material of Camfil´s standard filter elements is a proprietary fibre blend of cellulose and paper, what maximises dust holding capacity and promote dust release when pulse cleaned. Camfil´s medias are developed to provide the lowest pressure drop, longest service life and highest filtration efficiencies. The media can be treated to provide different properties which allows the handling of various dust types from different industrial processes.
Proprietary blend of cellulose fibres and polyester fibers for optimum dust release characteristics yielding long service life at high filtration efficiencies (colour: green). This media is used where dust is not explosive. We construct this media into our range of HemiPleat green filters.
Types of dust & fume (non explosive):
Typcial applications:
Industries:
Proprietary blend of cellulose and polyester fibres, additionally treated with flame retardant properties. This media is used where dust is typically not explosive but in processes where sparks might be generated (colour: white). We construct this media into our range of HemiPleat flame retardant filters.

Types of dust & fume (non explosive):
Typcial applications:
Industries:
Blend of cellulose and polyester fibres with a surface layer of nanofibres, additionally treated with flame retardant properties. This media is used where dust is typically not explosive but in processes where sparks might be generated (colour: white). The nanofibre layer helps to increase efficiency and the media is certified to dust class "M" in accordance to EN 60335-2-69. This media can help to reduce your emissions where that it is critical to your process. We use this media to construct our HemiPleat eXtreme flame retardant range of filters.
Types of dust & fume:

Basic spunbonded polyester with no treatments, heavy-duty and durable media (colour: white). Dura-Pleat standard media combines the best of both worlds: the high efficiency of pleated media and the versatility of synthetic materials. Filter elements with Dura-Pleat technology capture and release more pollutants when pulse-cleaned, resulting in a safer, cleaner work environment with less maintenance and provide lowest pressure drop. The media is certified to dust class "M" in accordance to EN 60335-2-69. This media can help to reduce your emissions where it is critical to your process.
