Filter bag

The filter bag is the core component of the bag filter. The materials used to make the filter bag include polypropylene, polyester, and nylon. The filtration accuracy ranges from 1 to 400 micrometers (μm). There are two manufacturing methods for the bag body: sewing and thermal fusion. The collar of the filter bag is categorized into steel rings and plastic rings, and the selection should be determined based on various factors such as the type of medium, filtration temperature, chemical conditions, and filtration efficiency.

Product Description

PP polypropylene filter bag



All use sanitary-grade filter materials that meet FDA requirements, with a multi-layer composite deep filtration structure that does not contain silicone oil, non-cleanable, and resistant to acid and alkali.
The optimal replacement pressure difference is 0.1 MPa, and the maximum should not exceed 0.16 MPa. The operating temperature is less than 80°C, and the filtration accuracy is 1-200 μm (nominal accuracy).


PE polyester filter bag



All use sanitary-grade filter materials that meet FDA requirements, with a multi-layer composite deep filtration structure that does not contain silicone oil, non-cleanable, and resistant to acid and alkali.
The optimal replacement pressure difference is 0.1 MPa, and the maximum should not exceed 0.16 MPa. The operating temperature is less than 110°C, and the filtration accuracy is 1-200 μm (nominal accuracy).


NYLONG nylon filter bag



All materials used are sanitary-grade filter materials that meet FDA requirements, featuring a multi-layer composite deep filtration structure that does not contain silicone oil, is non-cleanable, and is resistant to acids, alkalis, and solvents. The optimal replacement pressure difference is 0.1 MPa, and the maximum should not exceed 0.16 MPa. The operating temperature is less than 100°C, and the filtration accuracy is 25-400 μm (nominal accuracy).
