KWS Paper Frame Primary Filter

The paper frame primary filter serves as an essential "gatekeeper" in air purification systems, specializing in capturing large airborne particles exceeding 5μm, including dust, pet hair, pollen, and industrial debris. Engineered with multi-layered dense fiber media, its core advantages encompass three critical dimensions: Technical performance features a low airflow resistance design that maintains over 90% initial filtration efficiency while reducing energy consumption by 15-30%, ensuring optimal system operation. Economic efficiency is achieved through its cost-effective paper-frame construction and modular design, enabling hassle-free replacements that even non-technical users can perform within minutes. Safety and sustainability are prioritized with eco-friendly materials that eliminate secondary pollution risks. Widely implemented in central HVAC systems, electronics manufacturing cleanrooms, pharmaceutical facilities, and commercial complexes, this filter not only extends the service life of downstream HEPA or activated carbon filters by up to 40% but also significantly enhances indoor air quality (IAQ) by reducing particulate concentrations. For optimal performance, users should adhere to a 3-month inspection cycle, select filters matching airflow specifications (e.g., 300-500 Pa pressure tolerance), and ensure airtight gasket alignment during installation. With its unique combination of high-efficiency particle retention, energy-saving operation, and maintenance simplicity, the paper frame primary filter has established itself as the foundational solution for both industrial and residential air purification systems, delivering long-term cost savings and health protection.
