Synteq

Donaldson high-pressure filters

Donaldson heavy-duty high-pressure filters sit behind pumps and other prime movers to protect critical hydraulic components such as cylinders, motors and valves. All contain our SYNTEQ® synthetic filter media, specially developed by Donaldson for high efficiency liquid filtration. Working pressures range from 2000 psi up to 6090 psi; static pressures from 4500 psi up to 12000 psi.
