G3 GL Frame Replaceable Panel Pre-Air Filter from China Suppliers and Factory - High Efficiency and Durable Design
Application Area
Replaceable Pre-filters are widely used in Clean room, commercial and industrial air conditioning and ventilation systems, central air conditioning, and other related industries.
Filter Media Materials
The filter media is the part that actually performs the filtration. Common types include:
Metal Mesh
Characteristics: Typically aluminum or stainless steel mesh; washable, reusable, with good durability.
Used in situations requiring higher standards and reusable, but the cost is higher than that of paper media.

Synthetic Fiber
Characteristics: This is currently the most mainstream and common filter media. It is usually a non-woven fabric made from polyester fiber.
Advantages: The fibers are fluffy with uniform gaps, providing high dust-holding capacity; relatively low resistance; possesses a certain stiffness, allowing it to be self-supporting.
Form: The surface is usually pleated to create an uneven texture, increasing the filtration area and reducing resistance.

Glass Fiber
Characteristics: Now less commonly used in primary filters and more frequently used in medium-efficiency filters. It offers stable performance but is relatively brittle.
The Efficiency of Replaceable Pre Filter
The efficiency of currently available primary efficiency filters ranges from 40% to 90%, 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.
Service Life of Filters
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.

Frequently Asked Questions
Q1: What are the main applications for Replaceable Pre-filters?
They are widely used in clean rooms, commercial and industrial HVAC systems, central air conditioning, and various industrial ventilation setups.
Q2: What is the most common material used in these filters?
Synthetic fiber (polyester non-woven fabric) is the most mainstream due to its high dust-holding capacity, low resistance, and self-supporting properties.
Q3: How efficient are these primary air filters?
The efficiency typically ranges from 40% to 90%, depending on the specific media material and design requirements.
Q4: When should I replace my air filter?
Filters should be replaced when resistance reaches an unreasonable level or if there is a risk of captured dust being dislodged back into the airflow.
Q5: Can I wash and reuse the filter media?
Metal mesh filters (aluminum or stainless steel) are washable and reusable. However, most synthetic fiber media are designed for replacement once they reach capacity.
Q6: Do you offer custom sizes for these filters?
Yes, we support custom sizes to meet specific industrial or commercial ventilation requirements.
