Cardboard Frame G3 G4 Coarse Cotton Pre Air Filter Non-Woven Glass Fiber Material

Feature

Zhongjian South paper frame anti-epidemic filter is a pre-filter with good performance for ventilation system.

The outer frame uses 600g covered kraft paperboard paper frame, and the filter material uses polyester fiber cotton+diamond metal mesh.

The running resistance is low and the dust capacity is high.

Common porcine virus particles are small in diameter, and most of them can only be suspended in the air in the form of aerosol attached to the carrier (very few exist in the air alone).

As a pre-filtration system of pig house epidemic prevention system, it can prevent moisture and filter larger particles effectively and can be used together with high-efficiency filters to effectively prevent the spread of blue ear disease and swine asthma virus.

Characteristics of Pre-Air Filters

Filtration Efficiency:
- Pre-air filters are designed to capture larger particles such as dust, lint, and hair.
- Typically, they have lower filtration efficiency (e.g., 30–60%) compared to HEPA filters.
Purpose:
- Acts as the first line of defense to protect downstream filters (like HEPA) from becoming clogged by large particles.
- Extends the lifespan of high-efficiency filters by reducing their load.
Material:
- Made from coarse mesh, foam, or synthetic fibers, depending on the application.
Cost:
- Relatively inexpensive due to simpler construction and lower filtration efficiency.
Maintenance:
- Easy to clean or replace; often reusable if washable materials are used.
Applications:
- Commonly used in HVAC systems, air purifiers, and industrial equipment to pre-filter air.
