The OTR heavy duty radial seal air filter combines advanced radial seal technology with micro-fiber media to safeguard engine performance by effectively preventing unfiltered air ingestion. The specially coated surface resists clogging, consistently allowing air to flow, while its high dust-holding capacity helps minimize both maintenance frequency and downtime. Engine components remain protected as the micro-fiber media captures fine particles. Designed to meet rigorous industry standards, this air filter ensures reliable protection for engines.
