Hydraulic oil cleanliness is essential to the reliable operation of pumps, valves, hydraulic motors, cylinders, and precision control components. Solid contaminants can accelerate wear, reduce component performance, and contribute to unplanned equipment downtime.
ARGO-HYTOS hydraulic filter elements are designed to help control particulate contamination in hydraulic and lubrication systems. Depending on the filter technology selected, specific elements can also help remove water from suitable oils.
Hidroman provides product and application support for ARGO-HYTOS filter elements, including EXAPOR®MAX particulate filtration media, EXAPOR®AQUA water-absorbing elements, and replacement elements for compatible filtration equipment.
The EXAPOR®MAX product family includes filter elements designed to remove solid particles from hydraulic and lubrication fluids.
The EXAPOR®MAX 2 technology described on Hidroman’s webpage uses a three-layer filter medium combining glass and polyester fibers of different fineness with a hybrid support fabric made from stainless steel and polyester. Its plastic outer sleeve supports element protection and identification.
The design objectives include:
Reduced pressure drop
High dirt-holding capacity
Improved differential-pressure stability
Improved resistance to flow fatigue
Support for longer service intervals
Easier filter-element identification
Improved hydraulic oil cleanliness
ARGO-HYTOS product literature also references EXAPOR®MAX 3. EXAPOR®MAX 2 and EXAPOR®MAX 3 should not be treated as interchangeable product designations. Confirm the complete part number, filtration rating, and applicable manufacturer documentation when selecting a replacement element.
Water contamination in hydraulic oil can contribute to corrosion, changes in fluid properties, and reduced system reliability. Water may enter through ambient humidity, coolant leaks, spray water, fresh oil, or sealing problems.
EXAPOR®AQUA is a family of water-absorbing filter elements intended for suitable hydraulic and lubrication applications. The water-absorbing media can be combined with microfiltration material.
Hidroman’s webpage states an approximate water absorption capacity of 350 mL per element, depending on operating conditions. This should not be interpreted as a guaranteed capacity for every oil type or operating environment.
Selection should account for the fluid, initial water content, oil temperature, filtration unit, and target water level. Where an exact water-content measurement is required, an appropriate laboratory oil analysis should be used.
The following part numbers are listed on Hidroman’s current filter-element webpage or in its ARGO-HYTOS product list. This is a selection of listed items, not the complete ARGO-HYTOS product catalog.

The source table also contains numerical fields relating to capacity, power, or dirt retention. Because the table layout does not make every column assignment sufficiently clear, those values are not reproduced here as confirmed specifications. Verify them against the current manufacturer datasheet before ordering.
The following replacement filter elements appear in Hidroman’s ARGO-HYTOS product list.
| Part number | Filtration classification / efficiency information | Filter medium / description |
|---|---|---|
| V3.0724-08K1 | 16EX3 = β16(c) = 200 | EXAPOR®MAX 3; the product list also includes the value 10, whose unit should be confirmed. |
| V3.0934-06K1 | 10EX3 = β10(c) = 200 | EXAPOR®MAX 3; the product list also includes the value 5. |
| V3.0934-08K1 | 16EX3 = β16(c) = 200 | EXAPOR®MAX 3; the product list also includes the value 5. |
| V3.0941-08K1 | 16EX3 = β16(c) = 200 | EXAPOR®MAX 3; the product list also includes the value 5. |
| V3.0510-56K1 | 10EX3 = β10(c) = 200 | EXAPOR®MAX 3; listed by Hidroman as a replacement filter element. |
| V7.1560-103K8 | 03EX3 = β03(c) = 200 | EXAPOR®MAX 3; listed as a replacement element for units including UM 045 and the FNA 008/FNA 014 group. |
Understanding the beta ratio: The notation βx(c) = 200 refers to the beta ratio for particles of the specified size. For example, β10(c) = 200 indicates a 200:1 ratio for particles at 10 µm(c) under the applicable test conditions. It is not, by itself, a guarantee of absolute particle removal under every operating condition.
Separate values such as “5” and “10” in the source product list should not automatically be interpreted as micron ratings without verifying the table headings and manufacturer documentation.
V7.0833-03K1 is an ARGO-HYTOS filter element part number found in Hidroman’s previous product and quotation information. The associated stock reference is 44966200.
The available information does not establish a sufficiently verified filtration rating or compatible filter housing for this code. Before ordering, check the element label, dimensions, sealing arrangement, and filter housing against the current manufacturer documentation.
Selecting a replacement element requires more than matching a part number or nominal micron rating. Check the following details together:
Complete model number of the existing filter housing
Full part number printed on the original element
Filtration rating and beta ratio
Required flow rate and differential-pressure limits
Fluid type, viscosity, and operating temperature
Type of contamination to be removed, including particles or water
Element dimensions, seals, and connection details
EXAPOR®AQUA water-absorbing elements and EXAPOR®MAX particulate filters serve different purposes. The correct element must be selected according to the contamination type and compatibility with the installed filter housing.
With a suitable filter housing and compatible operating conditions, ARGO-HYTOS filter elements may be used in:
Industrial hydraulic power units
Production and process machinery
Mobile hydraulic equipment
Hydraulic and lubrication circuits
Oil service and off-line filtration units
Equipment requiring routine oil cleanliness control
Final application suitability should always be verified against the element’s manufacturer specifications and the hydraulic system requirements.
It captures specified sizes of solid particles from hydraulic oil to help maintain oil cleanliness. Actual filtration performance depends on the filter medium, filtration rating, and operating conditions.
EXAPOR®MAX is primarily intended for particulate filtration. EXAPOR®AQUA is designed to absorb water from suitable oils under appropriate operating conditions.
It indicates a 200:1 beta ratio for particles at 10 µm(c) under the applicable test conditions. The manufacturer's test method and operating conditions should be considered when evaluating filtration performance.
The part number is an important starting point, but it should be cross-checked against the existing filter housing, element dimensions, seals, and manufacturer data.
Provide the original element part number, filter housing model, required filtration rating, and application details. Hidroman can help evaluate the appropriate replacement element.
Maintaining hydraulic oil cleanliness starts with matching the correct filter element to the correct filter housing and operating conditions. Hidroman can help evaluate ARGO-HYTOS filter elements, filtration ratings, part numbers, and application compatibility.
