Candle type liquid filter bags are the filter bags used in candle type filters. Here is the relevant introduction:

Features:

- High-efficiency filtration: They can effectively retain solid particles, impurities, etc. in liquids, with relatively high filtration precision, and can meet the requirements of different industries for liquid filtration.
- Deep filtration: Based on the three-dimensional filter layer made of materials like needle punched felt, particles will be retained on the inner wall surface and in the deep layer of the filter bag due to the deep filtration mechanism, having a high capture efficiency for solid or colloidal particles.
- Diverse materials: Common materials include polyester, polypropylene, nylon, PP, PE, PPS, PTFE, etc. Appropriate materials can be selected according to the chemical properties, temperature, pH value, etc. of the filtered liquid. For example, polyester material is suitable for general industrial liquid filtration, while PTFE material can withstand strong acids, strong alkalis and high temperatures.
- Prevention of fiber shedding: The filtrate outlet surface has undergone special singeing treatment to prevent fibers from shedding and contaminating the filtrate, and also to avoid excessive blockage of the filter holes caused by traditional rolling treatment and thus shortening the service life of the filter bag.

Structural design:

- Ring mouth design: There are stainless steel ring mouths, PP ring mouths, PE plastic ring mouths, etc., ensuring firm and sealed installation.
- Bag bottom and bag top design: There are various designs for the bag bottom and bag top, such as flat bottom, round bottom, pointed bottom, open top, drawstring top, etc., adapting to different filtration requirements and installation methods.

Application fields:
They are widely used in the liquid filtration of industries such as electroplating, paint, ink, coating, food, chemical engineering, grain and oil, and pharmaceuticals.

Installation and maintenance:

- Installation: Put the filter bag onto the filter element of the candle type filter, ensuring that the installation is firm, without wrinkles or misalignment, and that the filter bag fits tightly with the filter element to avoid liquid short-circuiting and affecting the filtration effect.
- Maintenance: After being used for a period of time, it is necessary to clean or replace the filter bag regularly to prevent excessive accumulation of impurities from affecting the filtration efficiency and flow rate.
