Hydac 0330D, 0500D, 0650D, 0660D Series Pressure Filter Elements
Product Overview
The Hydac 0330D, 0500D, 0650D, and 0660D series are pressure filter elements manufactured by Hydac, a leading brand in fluid
technology. They are designed for precision filtration in hydraulic and lubrication systems, ensuring the cleanliness of operating
fluids and protecting critical system components.
Key Product Features
* Filtration Precision: The filtration accuracy ranges from 3 μm to 200 μm, depending on the specific element model and filter
media selected.
* Diverse Filter Media Options: Available media include glass fiber, solid plastic, metal mesh, metal wool, plain Dutch weave
mesh, and water-absorbing materials. This variety enables both absolute filtration (capturing nearly 100% of particles above
the specified size) and nominal filtration (capturing a high percentage of target particles).
* Excellent Pressure Resistance: Maximum allowable pressure differentials are 10 bar, 25 bar, 30 bar, or 210 bar, making the
elements suitable for low-to-high pressure operating environments.
* Wide Temperature Range: The maximum operating temperature is up to 100°C, compatible with all conventional hydraulic and
lubricating fluids.
* Optional Configuration: Most models are non-bypass valve designs; however, versions with integrated bypass valves are available
as optional configurations to meet specific system requirements.

Structural Design
* The filter elements adopt pleated filter media technology, which significantly increases the effective filtration area—this
design enhances contaminant holding capacity and extends the service life of the element.
* The filter core skeleton and end caps are constructed from 304 or 316 stainless steel. This material selection provides
excellent corrosion resistance and high-pressure resistance, ensuring structural stability even in harsh operating conditions.

Model Interpretation (Taking “0300D010ON” as an Example)
Hydac filter element models follow a standardized coding rule for easy parameter identification:

Note: For other models in the series (e.g., 0330D, 0500D), the first four digits (“0330”, “0500”) correspond to different size
specifications, while the subsequent codes follow the same logic for precision and media.
Application Fields
These pressure filter elements are widely used in hydraulic systems to remove contaminants such as metal wear debris, colloids,
and oxidation by-products from hydraulic oil. Typical application scenarios include:

* Construction machinery (e.g., excavators, loaders)
* Metallurgical and heavy equipment (e.g., rolling mills, forging presses)
* Petrochemical and energy industries (e.g., oilfield equipment, power generation systems)
* Industrial manufacturing (e.g., machine tools, hydraulic presses)
