Product Introduction When the dust gas through the filter bag. The dust will be block on the filter bag surface. The clean gas will pass away. So we can say that,The filter bag is the core of the dust filter. Or, you can consider it as the lung in our body. FILTER BAG REQUIRED STRICT SEWING TECHNOLOGY Please see our  picture poster as following: FILTER BAG SPECIFICATION The diameter of the filter bag should around 115 mm diameter to 200mm diameter.  The filter bag length should 2000 - 9000mm, the specifications of the commonly used filter bag is 125 - 170 mm diameter,  2000 ~ 6000mm length.The oval, flat, envelope and support ring types of filter bag, please be sure to enquiry for us with detailed information. After then, we should begin to processing. We will make the filter fabric first. CNP Co., Ltd. was founded in 2008, specializes in the field of air pollution control and bag filters.

The filter bag has the strict requirements on design, filter material cutting, woven technology etc. These requirements are very important for the filtration operation, maintenance and even the service life of the bag filter.
After then, we will sewing the filter fabric into the filter bag. For more detailed information, please reference the above processing picture.Â
When we finish the manufacture, the filter bag should begin to rechecking. As you know, even if one filter bag broken. It will be the 100% result for the dust filter equipment bad working. So, it is our the most important step for all. We must assure it can work correctly 100%. Not 99.9 or 99.99%. We must assure it 100% correctly. We must assure it 100% corrctly!. The important things three times....
