Dust type:
The shape and size of the dust will determine which filter material is required to capture the dust particles effectively. Process dust will contain particles of different sizes from those that are comparatively large and visible to the naked eye, to sub-micron particles which cannot be seen and which can cause significant harm to human health and damage to process equipment. One of the key benefits of PTFE membrane filters is the filtration efficiency of sub-micron particles, helping to comply with the increasingly stringent regulations relating to occupational health and the environment.
The shape of the dust rather than its size is the critical factor when considering its abrasive potential. Angular particles such as those found in cement have a far greater abrasive potential despite their small size. The airflow velocity transporting the dust, the filter unit and ductwork design are also important factors that need attention to ensure the service life of the filters is not significantly reduced due to degradation.
Advantages of ePTFE membrane: :
filters ePTFE membrane filter media can provide an array of benefits to manufacturing processes and add significant value.
1) Production savings
Increased system airflow can be achieved through reduced filter pressure drop, significantly reducing the cost per tone of product.
2)Reduced energy consumption
Maintains airflow at a reduced filter differential pressure (DP), therefore energy absorbed by the fan is reduced.
3)Reduced downtime
ePTFE filters require less frequent cleaning providing longer bag life and fewer bag changes
4)Reduced emissions
Near-zero emissions are possible to help comply with environmental and workplace health standards and regulations
