About this product
The 2721-1 is a factory-new aircraft air filter supplied with TRI-Release trace paperwork. It is a serviceable filter element intended to remove dust, particulates, and common contaminants from airflow paths in aircraft systems. Manufactured to aerospace workmanship standards, the unit restores the designed contamination control of the host system. The filter reduces wear on valves, pumps, sensors, and downstream components and helps keep environmental control, ventilation, and test systems clean and reliable.
