High-Quality F9 Glass Fiber Medium Pocket Filter - China Suppliers & Factory for Efficient Air Filtration
The core advantage of the fiberglass bag filter lies in its filter bags made of glass fiber material. This material gives the filter unique properties, enabling it to perform excellently in harsh environments such as high temperatures and corrosive conditions.
Main Material
Glass Fiber: Glass fiber is composed of extremely fine fibers drawn from molten glass. Depending on the manufacturing process and subsequent treatments, it can be classified into the following types:
The most commonly used type, offering good electrical insulation, mechanical strength, and heat resistance. Serves as the base material for high-temperature filter bags.
Provides better acid resistance and chemical corrosion resistance, making it suitable for applications involving corrosive gases, such as in the chemical industry.
With higher tensile strength and modulus, it is used in special scenarios where extremely high strength is required.
Frame Materials
The most common choice, offering good strength and low cost, meeting the requirements for most air handling units.
Lighter in weight with good corrosion resistance, often used in weight-sensitive applications or special environments.
For filters made of the same material, higher efficiency typically results in greater resistance and higher cost, while lower efficiency leads to reduced resistance and cost. Altering the air velocity will also affect resistance, efficiency, and the number of filters required, so appropriate selection should be made according to specific conditions.
As dust accumulates on the filter media, the resistance increases. When the resistance reaches an unreasonable level, the filter must be discarded. Sometimes, excessive resistance can cause previously captured dust to become dislodged and re-enter the airflow; when this risk arises, the filter should also be replaced.
