Founded in 1915, Donaldson manufactures a full line of industrial hydraulic filters and contamination control products.
Donaldson Hydraulics filters are used for the protection of machinery and components in hundreds of industrial applications, as well as heavy duty-mobile equipment.
Donaldson heavy-duty hydraulic filters sit behind hydraulic pumps and other prime movers to protect critical hydraulic components, such as hydraulic cylinders, hydraulic motors and hydraulic valves.
All filters contain SYNTEQ® synthetic filter media, specially developed by Donaldson Hydraulics for high efficiency liquid filtration. Working pressures range from 2000 psi up to 6090 psi. Static pressures from 4500 psi up to 12000 psi.

Donaldson Hydraulics DURAMAX®, medium pressure filters are well-known as the highest rated spin-on style hydraulic filters available. Most often they are used in return-line positions.
As spin-ons, they are particularly well-suited for duplex circuits.
HMK03 Duramax – working pressure: 1000 psi / 6895 kPa / 69 bar. Static pressure: 2000 psi / 13790 kPa / 138 bar. Flow range: 0-25 gpm / 0-95 l/min. HMK03 offers twice the pressure capability of competitive filters, yet is physically smaller than traditional housing/cartridge filter assemblies.
HMK04 (single head) & HMK24 (dual head) Duramax – working pressure: 500 psi/3450 kPa/34.5 bar. Static pressure: 1000 psi/6900 kPa/69 bar. HMK04 flow range: 0-35 gpm / 0-130 l/min. HMK24 flow range: 0-60 gpm / 0-230 l/min. HMK04/24 Duramax models offer high flow capacities, heavy-duty design, and a very wide choice of replacement filters.
HMK05 (single head) & HMK25 (dual head) Duramax – high flow: static pressure 800 psi/5520 kPa/55.2 bar. Working pressure: 350 psi/2413 kPa/24.1 bar. HMK05 flow range: 0-50 gpm / 0-189.3 l/min. HMK25 flow range: 0-100 gpm, 0-378.5 l/min. Full-range performance with Synteq® filter media for high-flow applications. The double element head means double flow capability, with two filters to hold more contaminant.
Donaldson Hydraulics low pressure hydraulic filters are the most commonly used type of filter in hydraulic circuits. Moreover, they are used most often as return line filters in applications with working pressures up to 150 psi and static pressure up to 300 psi.
Donaldson hydraulics 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.
TT15/30/60 – spin-on, tank top return filter. Working pressures to 100 psi / 6.9 bar. Rated static pressure to 150 psi / 10.3 bar. Flow range return up to 50 gpm / 189 lpm. Cellulose media, convenient tank top mounting.
FIK – in-tank, low flow. Working pressures up to 145 psi /10 bar. Rated static pressure to 217 psi / 15 bar. Flow up to 40 gpm / 150 lpm. FIK-low-flow filters are economical models with screw-on caps, ideal for in-tank applications. The head and inlet sit above the reservoir, with the housing in it.
FIK – in-tank, high flow. Working pressures up to 145 psi /10 bar. Rated static pressure to 217 psi / 15 bar. Flow up to 211 gpm / 800 lpm. The space-saving FIK-high-flow filters have heavy-duty heads, secured to a reservoir top by 2 or 4 bolts.
TI08/12/16 – tank immersed filters, low flow. Working pressures up to 100 psi / 6.9 bar. Flow range: up to 25 gpm / 95 lpm. TI series filters save space by mounting into tanks. Elements are easily replaceable through the filter cover. Different bowl lengths and a variety of media choices.
