What advantages does G4 Plate Air Filter have?
As the first barrier of ventilation and purification systems, the G4 Plate Air Filter is the most widely used primary filter equipment in industrial, commercial and residential scenarios. Compared with G1–G3 low-efficiency filters and medium & high-efficiency filters, it offers multiple core advantages covering filtration performance, operating adaptability, application cost, structural design, safety and durability. It meets basic air purification demands with balanced performance and cost. Its strengths are reflected in five dimensions: filtration performance, operating adaptability, application cost, structural design and safety durability, fully adapting to various basic air purification requirements.
In terms of filtration performance, G4 grade represents a high-quality level for primary filtration. Its filtration accuracy precisely matches basic purification needs and can effectively trap airborne dust, catkins, hair, fibers, mosquitoes and large particles larger than 5 μm with filtration efficiency exceeding 90%, thoroughly removing large-size pollutants. It intercepts impurities in advance to prevent them from entering equipment interiors, protecting downstream medium and high-efficiency filters and greatly extending the service life of high-precision filter media. This reduces the overall purification cost of the whole system. Compared with lower-grade primary filters, it delivers more stable filtration performance without impurity penetration or filtration failure, perfectly fitting basic air purification scenarios.
Low pressure drop is its standout feature in operating adaptability. The G4 plate filter adopts three-dimensional fluffy synthetic fiber filter media with evenly distributed fibers and a reasonable pore structure. Its initial pressure drop is extremely low, and it will not add extra load to fans of fresh air systems, central air conditioners and exhaust equipment during normal operation. Equipment can maintain normal air volume and wind speed without power increases, effectively lowering operating noise and power consumption. It avoids the drawbacks of high pressure drop and high energy consumption seen in high-efficiency filters and offers excellent compatibility with operating parameters of most conventional ventilation equipment.
In terms of application cost, this product stands out for outstanding cost performance. First of all, its procurement cost is low due to its simple structure and readily available raw materials, making it far cheaper than medium and high-efficiency filters. Secondly, it is reusable. The filter can be washed, air-dried and reused. Operators avoid the high recurring costs of disposable consumables. It can be repeatedly cleaned 3 to 5 times with proper maintenance, which greatly cuts long-term operation and maintenance costs. In addition, it prevents dust accumulation on internal machine cores, heat exchangers and air ducts of ventilation equipment, reducing equipment cleaning frequency and failure probability, and indirectly saving equipment maintenance and repair expenses.
For structural design, the plate-type structure is simple and practical. It is lightweight with a regular shape and no complex accessories, matching standard air outlets and filter slots of various equipment. The outer frame adopts paper, aluminum alloy or galvanized materials, which are sturdy, wear-resistant, deformation-resistant and rust-proof with good compression resistance. Installation, disassembly and cleaning do not require professional tools, and ordinary maintenance personnel can complete these operations quickly to improve maintenance efficiency. Moreover, the filter maintains good sealing performance after installation, free of air leakage and filtration dead zones for uniform filtration coverage.
In terms of safety and durability, the G4 Plate Air Filter uses environmentally friendly synthetic fiber materials free of toxic and harmful substances. No additives are used in production, so no volatile compounds or secondary air pollution will be generated during use. The material has favorable temperature resistance and can operate stably under conventional environments ranging from -20℃ to 80℃. It resists aging and embrittlement under temperature changes in normal working conditions. Meanwhile, the filter media has strong toughness, does not shed fibers or break easily, and delivers a stable service life. It can be deployed in most scenarios such as shopping malls, office buildings, factories and residences, with better practicality and stability than comparable primary filter products.
