KWS-011 AIR Filter - Customized Aluminum Frame Primary Filter from China Suppliers & Factory
Product Introduction
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.

Frequently Asked Questions (FAQ)
What is the primary function of the paper frame primary filter?
It serves as the essential first-line "gatekeeper" in air purification and ventilation systems, specifically designed to capture large airborne particles exceeding 5μm such as dust, pollen, pet hair, and coarse industrial debris.
What efficiency ratings do these filters satisfy?
The filters are engineered to comply with EN779 and ASHRAE52.2 standards, available in G3 (EN779) / MERV6 (ASHRAE52.2) and G4 (EN779) / MERV8 (ASHRAE52.2) ratings.
How does using this filter extend the lifespan of downstream filters?
By capturing over 90% of coarse particulates at the initial stage, it significantly prevents early clogging of downstream secondary HEPA or activated carbon filters, extending their operational lifespan by up to 40%.
What materials are used to construct this filter?
The outer frame is constructed from eco-friendly cardboard, while the internal media features multi-layered, high-quality polyester synthetic fibers structured with diamond mesh folding for maximum dust-holding capacity and durability.
What is the recommended maintenance and inspection frequency?
A 3-month inspection cycle is recommended. During replacement, ensure airtight gasket alignment and monitor pressure resistance so that it remains within the suggested ultimate resistance threshold (≤110 Pa).
Where is this filter commonly used?
It is widely implemented across central HVAC systems, commercial complexes, cleanrooms for electronics manufacturing, pharmaceutical production lines, general indoor ventilation units, and residential HVAC systems.
