ISO 16890 Air Filter Performance Testing System
The ISO 16890 air filter performance testing system is designed for evaluating the filtration performance of general ventilation air filters. The advanced test system accurately measures key parameters including filtration efficiency, initial pressure drop, final pressure drop, airflow performance, dust holding capacity and constant humidity according to ISO 16890 standards. It is widely used for testing primary air Filters, medium efficiency air filters, and HVAC filtration products, ensuring reliable performance, energy efficiency, and consistent product quality before delivery.
Air Filter Airflow Resistance testing equipment
CENCARB relies on professional testing capabilities and a complete range of air filter testing equipment, including activated carbon H₂S adsorption testers and filter pressure drop testing systems, to evaluate and optimize the key performance of chemical filters and various air filters. Our testing process complies with U.S. standards, European standards, and ISO 16890 requirements for air filter performance evaluation.
Looking ahead, CENCARB will continue to strengthen its product R&D and validation capabilities, providing global customers with more stable and efficient air filtration solutions.
