High quality F9 Glass Fiber Medium Pocket Filter

Pockets filters are widely used in central air conditioning ventilation systems, pharmaceutical, hospital, electronics, food and other industrial , and can also serve as the medium filter for high-efficiency air filters.

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:

E-glass: This is the most commonly used type, offering good electrical insulation, mechanical strength, and heat resistance. It serves as the base material for high-temperature filter bags.

C-glass: This type provides better acid resistance and chemical corrosion resistance, making it suitable for applications involving corrosive gases, such as in the chemical industry.

S-glass: With higher tensile strength and modulus, it is used in special scenarios where extremely high strength is required.

Frame Materials:

Galvanized Steel Sheet: The most common choice, offering good strength and low cost, meeting the requirements for most air handling units.

Aluminum Profile: Lighter in weight with good corrosion resistance, often used in weight-sensitive applications or special environments.

The efficiency pocket filters ranges from 45% to 95%, and they can be selected based on specific requirements. The rational selection of filter efficiency and face velocity contributes to comprehensive economic benefits.

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. The resistance of a filter increases with higher airflow rates. By increasing the surface area of the filter media, the relative velocity of air passing through the filter can be reduced, thereby decreasing the resistance.
