Paper partition primary filter

Product Overview:

Pre-filters, also known as paper frame pre-filters, are the primary pre-filter components in air purification and ventilation systems. Their core function is to intercept large particles of dust, hair, and fibers ≥5μm in the air, protecting downstream, more precise filter components and ventilation equipment.

Common applications and applicable industries are as follows:

I. Residential Scenarios
These filters are low-cost, easy to replace, and suitable for mild, low-humidity residential environments. They are mainly used in:

The return air end of household wall-mounted, cabinet, and central air conditioning systems to intercept hair, pet dander, and dust, preventing dust accumulation on the evaporator and mold growth, while reducing the frequency of air conditioner cleaning.

Pre-filters for household fresh air systems and ordinary air purifiers to filter out outdoor dust, pollen, and other large particles in advance, extending the lifespan of downstream, more expensive HEPA filters.

Pre-filters for the intake air of ordinary laboratory fume hoods, projectors, server racks, and other precision small equipment to prevent dust from entering the equipment. Protecting Precision Optical and Circuit Components

II. Commercial and General Industrial Scenarios

**General Ventilation and Air Conditioning: Used as a pre-filtration stage in centralized air conditioning systems of densely populated places such as general commercial office buildings, shopping malls, and conference rooms, improving indoor air quality and protecting core air conditioning components.

**Industrial Cleanroom Pre-filtration: Pre-filtration for cleanroom return air and local high-efficiency filters; pre-filtration for large air compressor intake air; ventilation filtration for program-controlled exchange server rooms, providing protection for high-precision filtration at the downstream end.

**Food Industry: Ventilation filtration in non-core areas of food processing and packaging workshops, meeting environmental waste disposal requirements; selecting filter media that meet food-grade standards is sufficient to meet the needs, intercepting dust and preventing contamination of food packaging.

**General Industrial Scenarios: Industries requiring clean air, such as electronic semiconductor processing plants, automotive painting workshops, and pharmaceutical processing plants, use it as the first-stage pre-filtration stage of the intake system to reduce the contamination rate of downstream filter components.
