⚙️ Industrial Sectors Painting workshops, food and beverage processing, and precision manufacturing.

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. Available in a range of materials:

🪵 Laminated Plywood

Most common type; low cost and good strength. Surfaces usually have an anti-corrosion coating.

🔩 Aluminum Profile

Lighter, more durable, and better fire resistance. Often used in high-standard clean rooms or special environments.

🧪 Stainless Steel

Used in biosafety laboratories, pharmaceutical plants, and 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 — Features a 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

📊

Efficiency Range Currently available high-efficiency filters range from 99.9% to 99.999999%, selectable based on specific requirements.

⚖️

Efficiency vs. Resistance Higher efficiency typically results in greater resistance and higher cost; lower efficiency reduces resistance and cost.

⚡ Note: Altering the air velocity will also affect resistance, efficiency, and the number of filters required. 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 immediately.

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 a V-type HEPA filter and how does it differ from standard HEPA filters?

A V-type HEPA filter uses a V-shaped (multi-pocket) pleat configuration that significantly increases the effective filtration area within the same frame footprint. Compared to standard flat HEPA filters, it supports much higher airflow volumes while maintaining low resistance, making it ideal for high-air-volume applications such as clean rooms and data centers.

❓ What filtration efficiency levels are available for V-type HEPA filters?

V-type HEPA filters are available across a wide efficiency range, from 99.9% up to 99.999999%, covering H13 and H14 grades and beyond. The appropriate efficiency level should be selected based on the cleanliness requirements of the specific application and the acceptable system resistance.

❓ What frame materials are available, and which should I choose?

Frame materials include laminated plywood (cost-effective, suitable for general environments), aluminum profile (lightweight, durable, fire-resistant — recommended for high-standard clean rooms), stainless steel (best for pharmaceutical or biosafety environments requiring frequent disinfection), and ABS plastic (for light-duty or special-purpose use). Your choice should be guided by the environmental conditions, budget, and required service life.

❓ How do I know when it is time to replace the HEPA filter?

The filter should be replaced when its resistance (pressure drop) rises beyond the acceptable operating threshold, or when there is a risk that accumulated dust may detach and re-enter the airstream. Regular monitoring of differential pressure across the filter is the most reliable method. Most systems use a pressure gauge or alarm to indicate when replacement is needed.

❓ Can V-type HEPA filters be customized to non-standard sizes?

Yes. Custom sizes are supported to meet specific installation requirements. When ordering, please provide the exact frame dimensions, required efficiency grade, airflow capacity, and frame material preference. Custom-sized filters are commonly used in retrofit projects or specialized HVAC systems.

❓ How does air velocity affect the performance and lifespan of a V-type HEPA filter?

Higher face velocities increase resistance (pressure drop), which raises energy consumption and can shorten filter lifespan. By selecting a filter with a larger media surface area — as achieved by the V-type design — the velocity of air through the media is reduced, resulting in lower resistance and extended service life. Selecting the appropriate face velocity during system design is key to achieving the best balance of performance and cost.
