characteristic:

1. Welded wire mesh adopts surface rust prevention treatment, fixed linear pleated structure, and is not easily deformed during use.

2. Seal the connection between the filter material and the outer frame to prevent air leakage at the connection between the filter material and the outer frame.

3. Use high-quality chemical fiber filter material and fix the filter material with wire mesh.

4. The filter material structure can fully utilize the filtering area to increase its dust holding capacity.

Material Description:

Type: Initial efficiency plate filter, initial efficiency folding filter;

Filter material: G1, G2, G3, G4 filter cotton;

Filtration efficiency: G1: 40% @ 5.0 μ m, G2: 65% @ 5.0 μ m, G3: 85% @ 5.0 μ m, G4: 90% @ 5.0 μ m (calculated method);

Filter frame materials: aluminum profile frame, aluminum folding frame, galvanized frame, stainless steel frame;

Protective nets: spray coated square mesh, spray coated diamond mesh, galvanized square mesh, galvanized iron wire or stainless steel iron wire

Filter size: Based on customer requirements, aluminum profiles can be selected in thicknesses of 21mm, 25mm, 46mm, and 50mm;

Main purpose:

1. Clean return air system

2. Pre filtration of local high-efficiency filtration device

3. Central air conditioning and centralized ventilation system pre filtration

4. Pre filtration of large air compressors

Pre filtering of ventilation and air conditioning systems for large civil buildings such as office buildings, conference rooms, hospitals, shopping malls, sports arenas, airports, and centralized ventilation systems for industrial plants.

Performance:

1. Primary air filters generally have the characteristics of long service life, low price, easy installation, and simple maintenance

2. The primary air filter series contains 100% artificial fiber filter material, which adheres a metal mesh to the air outlet end to prevent vibration and maintain consistent folding. The outer frame is made of a sturdy and moisture-proof aluminum alloy frame, which is sturdy and durable.

3. Folding shape, the filter material is fixed diagonally at the front and back of this frame, and the filter material is tightly adhered to the frame to prevent any air leakage. Its filtering area is 2-5 times that of a typical flat surface.

Replacement period:

Under normal conditions, the primary air filter needs to be replaced every 2-3 months; Or when the resistance of the filter reaches 250Pa or above, a new filter must be replaced; If the initial air filter uses washable filter material, it can be rinsed with water or a solution containing neutral detergent, dried, and then replaced, but it can only be cleaned two or three times at most, and then replaced with a new one.

Parameter description:

Note: Initial air filters can be customized according to customer needs for non-standard purposes!
