How to Choose Filter Bags: Understanding Their Characteristics Will Make It Clear

What role does the filter bag play in a filter? As another important component of a filter, regardless of the product, its quality largely determines the filtration effect for the user. It is also a critical part of the filtration process. When choosing a filter bag, it is generally recommended to use filter cloth produced by world-renowned companies, manufactured with professional production equipment, and paired with a patented structural ring. Shanghai Sffiltech Co.,Ltd has specialized in purification for 12 years and possesses rich experience in purification technology. When it comes to choosing filter bags, due to the variety of filter bag materials and the wide range of specifications in real life, it is important to select them according to your needs.

Filter bags are generally divided into many types based on their different performance characteristics, and each type has its own features. For instance, liquid filter bags mainly have the following four characteristics:

1. The seam at the opening of the liquid filter bag has been improved to eliminate high protrusions, thus preventing the occurrence of side leakage due to the absence of needle holes.

2. Liquid filter bags are made of various materials such as polyester, polypropylene, and nylon, with a wide range of filtration accuracy and high precision.

3. The labels indicating the product specifications and models on the liquid filter bags are all designed to be easily removable, to prevent contamination of the filtrate by the labels or ink during use.

4. Liquid filter bags do not cause silicone oil contamination problems, as they are produced using high-speed industrial sewing machines designed without silicone oil cooling.

There is a type of filter bag used in air conditioning systems, which, depending on the efficiency level, can be divided into three types: primary efficiency filter bags, medium efficiency filter bags, and sub-high efficiency filter bags. However, air conditioning system filter bags can also be divided by material into synthetic fiber filter bags, fiberglass filter bags, and non-woven fabric filter bags. Regardless of the type, the design of the outer frame is generally made of aluminum or galvanized frame material. Non-woven fabric filter bags also have their own characteristics; each filter bag is equally divided in width to prevent safety hazards caused by excessive expansion of the filter bag due to wind pressure.
