Introducing the primary air filter, meticulously engineered to excel in heavy-duty engine applications. Its high-efficiency cellulose media ensures outstanding performance, catering to a wide spectrum of demanding environments. With an increased number of media pleats, this filter boasts higher dust-holding capacity, ultimately leading to a longer filter life and reduced maintenance intervals. The corrosion-resistant, coated steel liners play a crucial role in supporting the media during operation, allowing for optimized airflow and enhanced efficiency. The innovative Pleatloc feature maintains uniform pleat spacing, preventing media from bunching and extending the filter's service life. This filter measures 16.00 inches in length, 4.22 inches inside diameter, 6.85 inches outside diameter, and adheres to ISO 5011 standards.
