Baldwin Element Filter PA1681-FN - NEW

The Baldwin PA1681-FN is a premium outer air filter element designed to protect diesel and gasoline engines in severe-duty operating conditions. Built with Baldwin’s PermaPleat® construction, this filter maintains even pleat spacing to maximize airflow while improving dust-holding capacity and service life.

Its heavy-duty radial seal gasket and reinforced metal end caps provide dependable sealing under vibration, pressure fluctuations, and extreme temperatures, helping prevent contaminants from bypassing the filtration system. The finned outer design improves structural support and installation performance in compatible housings.

Why It Stands Out

The PA1681-FN is especially well-suited for dusty environments where long service intervals and reliable engine protection are essential. Its rugged design, broad equipment compatibility, and strong contaminant control make it a dependable OEM-grade replacement for older heavy equipment fleets.
