The core advantage of this commercial air filter is its high-efficiency passive filtration and durable construction. The galvanized steel frame provides excellent structural strength and corrosion resistance, suitable for long-term use in harsh commercial building environments. The glass fiber filter paper has a 95% removal efficiency for 0.5μm particulate matter, effectively blocking most airborne pollutants in large spaces. The flange connection design allows for quick and easy installation and replacement, reducing maintenance time and labor costs. It can be customized to fit any standard central air duct size, meeting the specific air purification needs of different commercial projects.

This air filter can be customized to any size based on the central air duct dimensions, with a standard weight of 25kg per unit. It operates as a passive filtration device with no external power required, relying on the air pressure of the central air conditioning system to push air through the filter medium. The filtration efficiency reaches 95% for 0.5μm and larger particles, with a rated air flow of 1200 m³/h. The filter material is a non-woven glass fiber composite, with a working temperature range of 0-60℃ and applicable humidity of 30%-90%. It meets the EU CE and US EPA air filtration standards for commercial HVAC systems.

This commercial duct air filter is primarily applied to central air conditioning systems in commercial buildings, hospitals, schools, shopping malls, and industrial workshops. It is used to purify the recirculated air in large enclosed spaces, removing dust, pollen, and other airborne particulate matter, improving the indoor air quality for employees, customers, and patients. It is also suitable for clean room-level air purification systems in electronic manufacturing workshops, ensuring the air quality meets production standards.
