Air Filter Paper 14in x 5.25in

The OTR FILTERS Air Filter Paper 14in x 5.25in (model R10402) is a universal replacement air filter element engineered for tactical vehicles, generator systems, and equipment used in law enforcement and military field operations. Whether deployed in dusty environments, remote patrol bases, or during high-tempo training exercises, this cylindrical filter maintains intake system integrity by capturing particulates before they compromise engine performance. Field reliability depends on clean airflow—this element delivers that baseline requirement.

Construction centers on premium pleated paper media with integrated wire mesh support, a proven design that balances surface area for extended service life against flow restriction. The 14-inch diameter and 5.25-inch height are optimized for standard cartridge-style housings common across military-spec generators, compressors, and light-duty tactical equipment. White paper stock resists degradation from UV exposure and moisture, while the mesh backing prevents media collapse under normal operating pressure differentials. Installation is straightforward—remove the existing filter, verify housing compatibility, and insert the new element with proper sealing against the housing rim.

Maintenance personnel, equipment custodians, and field mechanics benefit from the universal fitment across multiple OTR-compatible platforms. This filter suits any air intake application requiring 14-inch diameter cartridge elements—from portable power systems to HVAC filtration in mobile command centers. For optimal performance, inspect the filter every 100 operating hours in dust-heavy conditions; replace when media shows visible dirt accumulation or when intake pressure rises noticeably. Keep spare elements on hand during extended deployments to avoid operational downtime.
