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 — Laminated Plywood: The most common type; low cost and good strength. Surfaces usually have an anti-corrosion coating.

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

Stainless Steel: Used in bio safety 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.

Polyurethane Sealant: The most commonly used type; 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 air tightness of the entire system.

Polyurethane Foam: The 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.

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)

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

A V-type HEPA filter uses a V-shaped (or W-shaped) multi-pocket configuration to significantly increase the effective filtration area within a compact frame. Compared to standard flat-panel HEPA filters, V-type designs offer lower initial resistance, higher air volume capacity, and longer service life, making them ideal for high-air-volume HVAC and clean room applications.

QWhat filtration efficiency level does this V-type HEPA filter achieve?

This V-type HEPA filter achieves H13 efficiency grade, with a particle filtration efficiency ranging from 99.9% up to 99.999999% depending on the specific model selected. The appropriate efficiency level can be chosen based on your application requirements and acceptable resistance thresholds.

QWhat frame materials are available for this V-type HEPA filter?

The filter frame is available in multiple materials to suit different environments: Laminated Plywood (cost-effective, standard use), Aluminum Profile (lightweight, fire-resistant, for high-standard clean rooms), Stainless Steel (for pharmaceutical, biosafety, and frequent-disinfection environments), and Plastic/ABS (for light-duty or special-purpose applications).

QHow do I know when it's time to replace the V-type HEPA filter?

The filter should be replaced when the measured resistance (pressure drop) across the filter reaches the maximum recommended level. Additionally, if excessive resistance causes previously captured dust particles to detach and re-enter the airstream, immediate replacement is required. Regular monitoring of differential pressure is recommended to determine the optimal replacement schedule.

QCan the V-type HEPA filter be customized in size?

Yes, custom sizing is supported. Customers can specify non-standard frame dimensions to fit existing HVAC systems or air handling units. Please refer to the Product Parameters table for standard sizes, and contact us directly for OEM or custom-dimension orders. Note that initial resistance tolerance is ± 10%.

QWhat is the difference between Separator-Free (Mini-pleat) and traditional separator technology in HEPA filters?

Traditional HEPA filters use aluminum or paper separators between pleats to maintain spacing. Separator-Free (Mini-pleat) technology eliminates these separators by using special pleating and curing processes to let the filter media hold its own shape. This results in a larger effective filtration area, lower airflow resistance, higher dust-holding capacity, and a more compact filter structure — all contributing to improved performance and longer service intervals.
