This high-airflow filter measures 18.75 inches in height with an outer diameter of 10.50 inches, and features a metal end cap with an inner top diameter of 0.66 inches and an inner bottom diameter of 6.50 inches, providing a secure fit in cylindrical air cleaner housings. It delivers an approximate 1000 CFM air flow rating to support continuous-duty operation in commercial trucks, construction equipment, agricultural machinery, industrial compressors, and other off-road diesel-powered systems requiring reliable air filtration.
