The D.I. Air Filter Testing Rig is designed and manufactured for precise performance evaluation of air filters used across HVAC systems, automotive applications, industrial filtration, cleanrooms, and air purification equipment. Engineered to simulate real operating conditions, the system accurately measures critical filter performance parameters including filtration efficiency, pressure drop, airflow resistance, dust holding capacity, and airflow characteristics. Built with precision instrumentation, advanced sensors, and an automated control system, the testing rig delivers highly repeatable and reliable test results while supporting quality assurance, research and development, and production validation. Its heavy-duty floor-mounted construction ensures stable operation under continuous testing conditions, while configurable airflow capacity and modular design allow the system to comply with various international filter testing standards. The D.I. Air Filter Testing Rig can be fully customized to suit customer-specific testing methods, reporting requirements, automation levels, and production environments.
