Replaceable (washable) primary filters

Primary filters play a vital role in central air-conditioning and centralized air supply systems, mainly used to filter dust particles larger than 5 microns in the air, and protect the performance and life of the next level of filters. According to different needs and application scenarios, primary filters can be categorized into three styles: plate, folded and bag. These filters not only come in various forms, but also have a variety of choices for their outer frame materials, including paper frames, aluminum frames and galvanized frames, etc. Filter materials cover non-woven fabrics, nylon mesh, activated carbon filter media and metal mesh, etc. Protective mesh is available in a variety of types, such as double-side sprayed iron wire mesh and double-side galvanized iron wire mesh. Its filtration grade generally covers G1, G2, G3, G4 and so on.

Your Reliable Manufacturer of Replaceable (washable) primary filters

Replaceable primary filter features

1. Sturdy metal frame structure

Replaceable primary filters are made of high-quality synthetic polyester fiber composite wire mesh and equipped with aluminum, stainless steel or galvanized frames. This sturdy metal frame structure not only ensures the durability of the filter, but also enables it to operate stably for a long time under the conditions of high airflow and low resistance.

2. Easy to replace, washable, long service life

The design of this type of primary effect filter focuses on easy replacement and cleaning, and users can carry out regular maintenance according to actual needs, thus extending the service life of the filter. This not only reduces the operating costs, but also improves the overall efficiency of the system.

3. High airflow and low resistance

In terms of design, these filters are made of high-quality synthetic polyester fiber composite wire mesh, which is able to provide high airflow while maintaining low resistance. This is particularly important in areas with high air quality requirements such as semiconductors, pharmaceuticals, food, electronics and hospitals, ensuring efficient operation of air conditioning systems.

Applications

Replaceable primary filters are widely used in the following fields:

Semiconductor industry: In the process of semiconductor manufacturing, tiny particles in the air may cause serious contamination of the product, so it needs high efficiency pre-filter to guarantee a clean environment.

Pharmaceutical industry: the production of pharmaceuticals has extremely strict requirements on air quality, and the preliminary filter can effectively filter large particles in the air to ensure a sterile environment for pharmaceutical production.

Food processing: food safety is related to consumer health, the primary filter can effectively remove impurities in the air to ensure a clean environment for food processing.

Electronic industry: In the manufacturing process of electronic products, the dust and particles in the air may affect product quality, and the application of primary filters can improve the product qualification rate.

Hospitals: The medical environment has extremely high requirements for air quality, and primary filters can effectively filter dust in the air to protect the health of patients and medical personnel.
