Description
M131802 & M131803 Outer and Inner Air Filter Set for Commercial Lawn Equipment
The M131802 & M131803 Air Filter Set is a complete dual-stage air filtration solution designed for commercial lawn mowers, zero-turn mowers, turf equipment, and utility machinery. Featuring both a primary (outer) filter and a safety (inner) filter, this filter set provides superior engine protection against dust, grass clippings, pollen, and airborne debris commonly encountered in landscaping and grounds maintenance operations.
Commercial mowing equipment often operates in extremely dusty conditions where engine protection is critical. The combination of the M131802 primary air filter and M131803 safety filter helps maintain clean airflow while preventing contaminants from reaching sensitive engine components. This results in improved engine performance, reduced maintenance costs, and longer equipment service life.
Manufactured to OEM-quality standards, this air filter set is widely used by landscaping contractors, golf course maintenance teams, municipal grounds departments, equipment rental companies, and aftermarket distributors.
