The 3 Line Filtration Kit With Side-By-Side Filter from Buyers Products has everything you need to set up a high-capacity 3 line installation with return line filtration, including a 25 micron filter. Having a third line -- a dedicated return hose -- in your dump pump hydraulic system gives you more efficient operation from faster cycle times. Adding a return line filter keeps fluid free from contaminants and extends the life of your system components. This 3 line installation is specially designed to handle high return flow rates up to 90 GPM. It features dual 25 micron return line filters in a side-by-side design.
