Product Introduction
Filter Media Materials
🔬
Separator-Free (Mini-pleat) Technology
A more advanced technology that uses special pleating and curing processes to allow the filter paper itself to maintain its shape, eliminating the need for traditional separators. This further increases the filtration area and reduces resistance.
🪟
Frame Function
Provides structural strength to the filter and facilitates installation and sealing. Materials include: Laminated Plywood (most common; low cost and good strength, with anti-corrosion coating); Aluminum Profile (lighter, more durable, better fire resistance, often used in high-standard clean rooms); and specialized materials below.
⚙️
Stainless Steel
Used in biosafety laboratories, pharmaceutical plants, and other applications requiring frequent disinfection and high corrosion resistance.
🧱
Plastic (e.g., ABS)
Used for some light-duty or special-purpose filters.
Sealant (Gasket Sealant)
🛡️
Function
Securely seals the filter media pack within the frame to prevent the leakage of unfiltered air (bypass). This is crucial for ensuring filter efficiency.
🧴
Materials
Polyurethane Sealant: Most commonly used; offers good elasticity and adhesion strength.
Silicone Sealant: Wider temperature resistance range and better aging resistance.
Hot-Melt Sealant: Fast curing and environmentally friendly.
Gasket (Sealing Gasket)
🔩
Function
Installed between the filter frame and the installation rack to ensure the airtightness of the entire system.
🧩
Materials
Polyurethane Foam: Most common type; offers good compression set and resilience.
Neoprene Rubber: More durable and offers better aging resistance.
The Efficiency of HEPA Filter
⚡ The efficiency of currently available high-efficiency filters ranges from 99.9% to 99.999999%, 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 (FAQ)
Q
What is a V-type HEPA filter and where is it typically used?
A V-type HEPA filter is a high-efficiency particulate air filter designed in a V-shaped pleat configuration to maximize filtration surface area. It is widely used in large clean rooms (such as semiconductor factories and pharmaceutical workshops), data centers, commercial buildings, and industrial sectors including painting workshops and precision manufacturing.
Q
What filtration efficiency levels are available for V-type HEPA filters?
V-type HEPA filters are available in a wide range of efficiency levels, from 99.9% up to 99.999999%. The appropriate efficiency level should be selected based on specific application requirements, balancing air cleanliness needs against system resistance and overall operational costs.
Q
What frame materials are available for V-type HEPA filters?
V-type HEPA filters can be framed with several materials: Laminated Plywood (most common, cost-effective), Aluminum Profile (lightweight and fire-resistant, ideal for clean rooms), Stainless Steel (for pharmaceutical and biosafety environments requiring frequent disinfection), and Plastic (ABS) for light-duty or special-purpose applications.
Q
How does air velocity affect the performance of a HEPA filter?
Air velocity directly impacts filter resistance, efficiency, and the number of filters required in a system. Higher air velocity increases resistance, which can reduce filter life and increase energy consumption. By increasing the filter media surface area, the velocity of air passing through the media can be reduced, thereby lowering resistance and potentially extending filter service life.
Q
When should a V-type HEPA filter be replaced?
A V-type HEPA filter should be replaced when the accumulated dust causes the system resistance to reach an unreasonable or preset maximum level. Additionally, if excessive resistance causes previously captured dust particles to become dislodged and re-enter the airflow, immediate replacement is necessary to maintain air quality and system performance.
Q
What is the advantage of Separator-Free (Mini-pleat) technology in HEPA filters?
Separator-Free (Mini-pleat) technology uses special pleating and curing processes that allow the filter media itself to maintain its pleated shape without requiring traditional aluminum or paper separators. This results in a significantly larger filtration area within the same frame size, lower airflow resistance, and improved overall filter performance and energy efficiency.
