Volant's high performance MaxFlow 5, 5 layer oiled cotton gauze air filters are made of the highest quality textiles, pleated between a top and bottom aluminum screen. Each filter comes pre-oiled and ready for use. This design will allow the highest air flow rate possible and a very long filter life and maintenance intervals (up to 40K miles depending on driving conditions). Use Volant's two stage cleaning kit to thoroughly clean and re-oil the filter. We recommend cleaning the MaxFlow 5 filter only when necessary. Inspect the filter every 12,00-15,000 miles to ensure peak operation.
Volant Primo Diesel air filters are made with 8 layers of the highest quality textiles; pleated between a top and bottom aluminum screen, designed specifically for severe duty trucks. Each filter comes pre-oiled and ready for use. This design will allow the highest air flow rate possible and a very long filter life and service intervals of up to 40,000 miles depending on driving conditions. We recommend cleaning Primo Diesel air filters only when necessary. Inspect the filter every 12,00-15,000 miles to ensure peak operation.
Volant Pre-Filters are factory treated using a proprietary hydrophobic process and are manufactured from the same durable polyester material as their race proven regular style. This unique material contains uniform micron openings that will filter out debris .005 or larger. This pre-filter will prevent splashes of water, mud and sand from saturating your air filter.
By using Donaldsons PowerCore Filtration technology submicron contaminants load on the surface rather than collecting in the depth of the filter. This boosts efficiency and increases performance on your aftermarket air intake system. The filter media wont deteriorate as easily as traditional cotton/gauze filters. This is why we warranty our replacement air filters for 4 years or 150,000 miles in urban conditions whichever comes first.
