Frameless high-efficiency filter

Key Product Features:

1. Excellent Filtration Performance: Filters micro-suspended particles of 0.3µm and below, with mainstream efficiency levels reaching H13~U15. High-end models achieve a filtration efficiency of over 99.999% for target particles, effectively intercepting bacteria, viruses, ultrafine dust, and other pollutants.

2. Structural Design Advantages: Utilizes hot melt adhesive as the filter layer separator instead of traditional partitions, resulting in a lighter and thinner profile for the same dimensions. This allows for a larger filtration area, higher dust holding capacity, lower operating resistance, longer service life, and easier installation.

3. Good Environmental Compatibility: Avoids the use of unnecessary metal components, simplifying waste disposal and meeting modern environmental requirements. Except for special high-temperature/high-safety scenarios, it can directly replace traditional partitioned filters.

Main Application Scenarios:

• Industrial Sector: Terminal air filtration in electronic semiconductor workshops, precision manufacturing plants, food and cosmetic production workshops, and cleanrooms;
• Medical and Pharmaceutical Sector: Hospital operating rooms, pharmaceutical workshops, biological laboratories, and other places with extremely high cleanliness requirements;
• Civil Sector: Core high-efficiency filter element for household fresh air systems and air purifiers.

Common frame materials&filter element materials& standard frame dimensions:

I. Common Frame Materials
The most common frame material is aluminum alloy (usually anodized for high strength, lightweight, and corrosion resistance). Galvanized steel or stainless steel can also be used depending on the application scenario to meet the requirements of different temperature, humidity, and cleanliness levels.

II. Common Filter Cartridge Materials
The core filter material is generally made of specialized ultra-fine glass fiber filter paper. For some lower-requirement applications, PP high-efficiency filter media may be used. Ultra-fine glass fiber has extremely high filtration efficiency for particles, bacteria, and dust as small as 0.3µm, with typical efficiencies reaching H13~U15 levels.

The filter layers are separated by hot-melt adhesive lines instead of traditional partitions, allowing for a larger filtration area with a thinner thickness, reducing air resistance and extending service life.

Frameless HEPA filters have standardized industry dimensions, but non-standard customization is also supported. Common specifications are as follows:
