1. long work life Filter bag is the core of the dust filter components. The filter bag has the strict requirements on design, filter material cutting, woven technology etc. These requirements are very important for the normal operation of the bag filter and convenient maintenance, and it is great significance to enlong the service life of the filter bag. 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.  First of all, we need to confirm the detailed size of filter bag with our customer. After received your confirmation or agreement, we should begin for processing. If the drawing can not clearly or need filter bag sample to trail installment, we should provide the confirmed size filter bag sample before the purchase order processing. 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.... Working occasion CNP Co., Ltd. was founded in 2008, specializes in the field of air pollution control and bag filters. Including engineering design, planning, consulting, equipment research and development, manufacturing, sales, installation and commissioning, as well as production and services. Based on the high starting point, CNP Co., Ltd., with a positive and upward pioneering spirit, will further create brilliancy as to technological innovation, intellectual property rights and independent brand strategy.  1. long work life Filter bag is the core of the dust filter components.

2. High dust collection efficiencyÂ
3. Many types of material can suit for many industry and dedusting cases
FILTER BAG FUNCTION
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
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.
Please see our  picture poster as following:
FILTER BAG SPECIFICATION
Â
After then, we should begin to processing. We will make the filter fabric first. After then, we will sewing the filter fabric into the filter bag. For more detailed information, please reference the above processing picture.Â
Â
Please see the following working circumstance. The filter bag is often used in dust filter equipment and replace the filter bag in dust filter equipment. So, please reference the dust filter (dust collector) working occasion. Please be sure to inquiry us by following e-mail table directly. Hope that we can give you more professional suggestion for reference.
