Product Description

Disposable Pleated Primary Panel Filter

Pleated air filter is an efficient and economical air pretreatment device. It adopts a unique structural design and innovatively combines metal mesh and deep folding technology on the basis of traditional plate filters.

Structure
Frame	Usually made of aluminum alloy, galvanized steel or cardboard frame, used to fix and support the overall structure of the filter.
Filter media	The filter material covered on the grid support, mostly synthetic fibers, has better filtration effect and air circulation.
Support grid	The grid structure covering the surface of the filter media, used to support the filter material to maintain a stable filtration effect.
Auxiliary parts	Such as sealing strips, also known as gaskets, used to ensure the overall sealing of the filter, generally optional 3mm EVA or 5mm EPDM.

Its core is composed of a high-strength aluminum frame/galvanized frame/cardboard frame to form a frame. The interior is made of special polyester fiber filter material through a folding process, significantly increasing the filtration area. A layer of metal protective net is covered on the air intake surface, effectively preventing filter material damage and enhancing structural stability.

Pleated filters are typically of the G4 primary filtration grade, capable of efficiently intercepting large particle pollutants such as dust and flocs larger than 5μm. Meanwhile, with their unique wavy folded design, they increase the dust holding capacity by over 40%, significantly extending their service life.
The metal mesh design makes it particularly suitable for industrial environments with high wind speeds or containing sharp particles, capable of withstanding high wind pressure without deformation. 

Pleated air filter is mainly applied in scenarios such as central air conditioning fresh air systems, industrial plant ventilation equipment, and pre-treatment in painting workshops. It can be used independently as a primary filtration unit or as a pre-protection device for high-efficiency filtration systems. It is an ideal choice that balances filtration performance and economy.

Features

1. Metal mesh protection: The surface of the filter material is covered with a metal mesh to enhance structural strength and prevent damage to the filter material.
2. Deep folded design: The filter material adopts a wavy folded process, increasing the filtration area and raising the dust holding capacity by more than 40%.
3. Primary filtration (typically at G4 efficiency) : Effectively intercepts large particle pollutants such as dust, pollen, and flocs larger than 5μm.
4. Low wind resistance: Optimize the airflow channel to reduce system energy consumption.
5. Stable frame: Aluminum frame, galvanized frame or cardboard frame,  suitable for various environments.

Applications

1. Central air conditioning fresh air system: Pleated air filter can be used for primary filtration in commercial buildings and hotels.
2. Industrial ventilation equipment: Pre-treatment of air intake in factory workshops and warehouses.
3. Painting/Welding workshop: Intercept metal dust and particles to protect the back-end equipment.
4. Electronics/Pharmaceutical workshop: As a pre-protection for high-efficiency filtration systems.
5. Public transportation places: Pre-filtration of fresh air units in subway stations and airports.
6. Food processing plants: Block large particle pollutants to make the environment meet hygiene standards.
