Product Details

Application Area

🏢 Mainly used in central air conditioning and integrated air supply systems, it can be employed for primary and intermediate filtration in air conditioning systems to protect the HEPA filters and the system.

Filter Media Materials

Frame

📄 Paper Frame

Low cost, often used in standard commercial applications where high strength and weather resistance are not critical.

🔩 Galvanized Steel Frame

Most commonly used material. Offers high strength, resistance to deformation, corrosion resistance, and a long service life — suitable for most industrial and commercial HVAC systems.

⚡ Aluminum Profile Frame

Lightweight with excellent corrosion resistance, often used where weight is a concern or in humid environments.

🛡️ Stainless Steel Frame

Highest strength and best corrosion resistance. Primarily used in demanding industrial environments with special hygiene or anti-corrosion requirements.

Filter Media

Fiberglass, Polyester Fiber (PET), Composite Polypropylene (PP) Material, Synthetic Blends.

Separators

📜 Separator Paper

Characteristics: Usually specially treated kraft paper or aluminum foil composite paper, folded into a zigzag (corrugated) shape placed between each pleat of the filter media.

✅ Advantages: Low cost and mature technology.

⚠️ Disadvantages: Can soften and deform in humid environments; not suitable for applications with ultra-high hygiene requirements (can harbor mold).

🔧 Aluminum / Metal Separators

Characteristics: Made from thin aluminum foil in a corrugated structure.

✅ Advantages: Extremely high strength, completely damp-proof, will not harbor bacteria, and easy to clean (in some washable filter types).

⚠️ Disadvantages: Higher cost and heavier weight.

The Efficiency of Medium Filter

65% – 95%

The efficiency of currently available medium-efficiency filters ranges from 65% 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.

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 (FAQ)

❓ What is the main application of aluminium foil separator medium filters?

These filters are mainly used in central air conditioning and integrated air supply systems. They serve as primary and intermediate filtration stages to protect HEPA filters and the overall HVAC system from dust and particulate contamination.

❓ What efficiency range do medium-efficiency filters cover?

Medium-efficiency filters are available in an efficiency range of 65% to 95%. The appropriate efficiency level can be selected based on the specific application requirements and desired economic benefits.

❓ What frame materials are available for medium filters?

Four frame material options are available: Paper Frame (low cost, standard use), Galvanized Steel Frame (most common, high strength and corrosion resistant), Aluminum Profile Frame (lightweight, ideal for humid environments), and Stainless Steel Frame (highest strength, suitable for demanding industrial or hygiene-sensitive environments).

❓ What is the difference between paper separators and aluminium separators?

Paper separators are lower in cost and use mature technology, but they can soften in humid conditions and may harbor mold. Aluminium separators are stronger, completely moisture-proof, and do not harbor bacteria — making them ideal for cleanrooms or washable filter applications, although they are heavier and more expensive.

❓ How do I know when to replace a medium-efficiency filter?

A filter should be replaced when the measured resistance reaches an unreasonably high level or when there is a risk that accumulated dust may become dislodged and re-enter the airflow. Regular monitoring of pressure drop across the filter is recommended to determine the optimal replacement time.

❓ Can the filter dimensions be customized to specific requirements?

Yes. Custom sizes are supported to meet specific installation requirements. The initial resistance tolerance is ± 10%, and customers are encouraged to provide their dimensional specifications when placing an order.
