G4 pleated panel filter Definition
The G4 pleated panel filter is a pre-filtration product designed for HVAC systems, air handling units (AHUs), and various ventilation systems. It uses synthetic fiber filter media reinforced with a metal mesh, and its pleated design provides a large filtration area, low resistance, and high dust-holding capacity.
This filter is engineered to deliver high airflow, durable structural performance, and long service life, while also meeting the needs of wholesale customers in terms of pricing, stability, supply capability, and customization options.

Application Case Analysis
Case 1: Ventilation System Upgrade at an Automotive Parts Factory
A stamping and processing workshop at an automotive parts factory faced a serious dust issue. Its original flat pre-filters had a lifespan of only 1–2 months, requiring frequent replacement. After switching to SYNRUI's customized G4 pleated panel filters featuring three times the filtration area and stable metal mesh support-the actual service life was extended to 3–4 months. The replacement frequency was reduced by 40%, and annual maintenance costs decreased by 30%.
Case 2: Fresh Air System Optimization at a Food Processing Plant
Food processing plants have strict air cleanliness requirements, but the environment is humid, and ordinary paper filter media is prone to moisture damage and deformation. SYNRUI's design uses synthetic fiber filter media combined with an aluminum expanded mesh cover, maintaining good structural integrity and stable resistance even after 90 days of continuous operation in high-humidity conditions. Customer feedback indicates that airflow in the fresh air system remains more stable, reducing fluctuations in system energy consumption.
Case 3: Reduced Operating Costs for Central Air Conditioning in Large Commercial Complexes
Central air conditioning systems in shopping malls operate at high air volumes for long periods, making filter resistance a key concern. With superior performance and a low initial resistance of 30–45 Pa, SYNRUI G4 pleated panel filters made in china help reduce the energy consumption of the main fan by approximately 8–12%. For a shopping mall of about 10,000 ㎡, this filter can save more than 10,000 yuan in electricity costs annually, making it a more cost-effective replacement option.
