Pro DRY S Media:
This filter features "Oil-Free" 3-Layers Of Progressively Finer Porosity 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 direct replacement for the popular Donaldson paper filter (P/N: ECB085011) with the ridid flange. 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. Pleats are 30% taller that the paper alternative.

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.

Magnum SHIELD Pre-Filter:
Protects your performance air filter from debris, repels water and keeps your air filter clean longer with minimal affect on air flow.

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