Pro DRY S Media:
This filter features "Oil-Free" 3-Layers of synthetic media for maximum convenience with Excellent Filtration Efficiency. The progressive layering of media allows the filter to flow at high levels even when dirty. The Pro DRY S filter media has been tested at 99.27 percent filtration efficiency.

Massive Washable/Reusable Filter:
With 8-1/2" Base x 8-1/2" Top x 11" Height with a 4" flange, this filter is a flexible flange version of the popular Donaldson paper filter (P/N: ECB085011). Rather than throwing the filter away, you can now wash the filter and reuse it over and over again. Since this filter is oil-free, servicing does not require re-oiling.

Rounded Open Pleats:
aFe performance air filters use a rounded, evenly spaced pleat design which produces more useable filter surface area for increased flow and greater dust holding capacity.

100% polyurethane construction:
To allow multiple cleaning cycles, the top and base are made of 100% pliable polyurethane that does not deteriorate with time or exposure to heat and chemicals.

aFe Power Universal Clamp-on performance filters have a limited 2-year warranty.
