Donaldson was founded in 1915 when Frank Donaldson Sr. developed a simple air cleaner to solve a farmer’s tractor problems. Today, the brand is present in 19 countries around the worlld.
Donalson industrial air filtration technology is applied to a variety of industries and environments, including: welding, pharmaceuticals, woodworking, chemical, metal fabrication, foundries, food processing and composites.
Thus, Hydrola offers a large choice of filter housings, filter heads, replacement cartridges, spin-ons or hydraulic accessories.
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. Working pressures range from 2000 psi up to 6090 psi; static pressures from 4500 psi up to 12000 psi.
Medium Pressure Filters
working pressures range from 350 psi up to 1000 psi; static pressures from 800 psi up to 2000
Low Pressure Filters
Low pressure filters are the most commonly used type of filter in hydraulic circuits, used as return line filters in applications with typcial working pressures up to 150 psi and static pressure up to 300 psi. Donaldson offers flow/pressure combinations to fit most applications. Continuous filtrations of bulk fluids through dedicated off-line circuits or kidney loops helps keep fuel, oil and lubricants clean.
