Oil-Free Filtration - You never have to oil a Dryflow air filter, which provides many advantages over cotton-gauze. Not having to oil the filter reduces cleaning/servicing time from several hours to minutes, and eliminates the chance of oil migration up the inlet pipe. The reduced weight of the filter (because of a lack of oil and wire mesh) reduces stress on the inlet pipe and allows us to design the filter for unmatched durability. Easy to Clean - The Dryflow filter cleans in minutes using soap and water. It will dry in minutes and be ready for re-installation. At the track or on the trail, you can quickly clean the filter by removing and knocking it against your hand to release a majority of the dirt. Since oil is not used, the dirt will not cake to the media’s surface. Ultra Durable - The Dryflow filter has several durability advantages over oiled cotton-gauze and even competitor dry filters. The lightweight media is constructed of a non-woven polyester, which allows the Dryflow to take abuse and still perform and look like new. An internal nylon-reinforced cage (most conical filters) provides structural rigidity so the filter will never collapse, and the lightweight urethane base, lid and edge seal will never deteriorate. The end product is a lightweight filter that will last forever. We guarantee it for life. The Best Filtration - Dryflow delivers an Industry-Leading filtration efficiency of 99.52% cumulative filtration efficiency and filters out particles as small as one Micron in ISO 5011:2000 independent performance filtration testing using A-2 Fine Test Dust. While our competitors test using Coarse Dust, we have found that A-2 Fine Test Dust testing is the most accurate form of filtration testing for real-world conditions, since the harshest dirt to affect an engine is sub-two micron.
