The Racor Division of Parker Hannifin offers the ECO II series high-soot capacity intake filters for marine applications. The filters are designed for applications where high-soot concentrations are present. Marine-grade filter media extends service life in such environments when compared to conventional heavy-duty, paper-type air cleaners. ECO II intake filters are currently available in two sizes: 15 x 15 in (381 x 381 mm) or 15 x 24 in (381 x 610 mm). Features and benefits include extended service life, increased capacity, and lower pressure differential for improved power and fuel economy.
