The primary filter is suitable for the primary filtration of the air conditioning system, mainly used to filter dust particles above 5μm. The primary filter has three styles: plate, folding, and bag. The materials are also similar. The outer frame materials include paper frame, aluminum frame, galvanized iron frame, and the filter material includes non-woven fabric, nylon mesh, activated carbon filter material, and metal mesh. The protective nets include double-sided plastic-sprayed wire mesh and double-sided galvanized wire mesh. Today, I will introduce you to the foldable primary filter.
The foldable primary filter is characterized by including a horizontal frame, a vertical frame, a thin column, a filter layer, a horizontal frame elastic plug, a spring clip, a ring, a spring, a column hole, a bolt, and a vertical frame elastic plug. The utility model is convenient for disassembly and assembly, brings convenience to the disassembly and cleaning of the filter, and greatly reduces the space required for transportation, improves transportation efficiency, and saves transportation costs. The thin column and the horizontal frame are inserted and connected for easy disassembly, assembly, and transportation. The filter layer is folded by the thin column, which increases the filter area and improves the filtration efficiency. The spring clamp fixes the two ends of the filter layer and is easy to disassemble. The horizontal frame is flexible The structure of the plug and mullion elastic plug makes the four sides of the filter layer tightly connected with the horizontal frame and vertical frame, which enhances the sealing performance and prevents the gas to be filtered from leaking. The horizontal frame elastic plug and mullion elastic plug is movably connected with other parts, Easy to disassemble and assemble.
Features of the product:
1. The outer frame is made of the hard paper frame or aluminum profile, and the non-woven chemical fiber cloth is folded and formed to greatly increase the filtering area.
2. Some are supported by metal mesh, the structure is firm and stable, and the spacing is balanced
3. High pleated filter screen. Make the filter reach a large dust holding capacity when the resistance is small
4. Good versatility, long service life, low economic operation cost.
5. Generally used for primary filtration of ventilation systems, but also suitable for air conditioning ventilation systems that only require primary filtration.
6. Purification and filtration of general indoor ventilation systems in industrial and commercial applications, and preliminary filtration of household air-conditioning purification equipment.
1. Pre-filtration of general air conditioning and ventilation systems to avoid dust pollution inside the system;
2. Pre-filtration of large air compressors;
3. Centralized ventilation and air-conditioning system and return air filtration in cleanroom can prolong the service life of the subsequent high-efficiency filter;
4. The pre-filtering of the ventilation system of general industrial plants meets the general clean air requirements;
5. Pre-filtering of air conditioning systems in general buildings;
6. Pre-filtering of rail transit public basic air-conditioning system.
