Product Description

Hydac series such as 0750R003 are return line filters designed for hydraulic systems. They are used to filter the oil in the return line, intercept solid particles and colloidal contaminants, and ensure the cleanliness of the hydraulic system. The detailed introduction is as follows:

1. Model Meaning

Taking the common model "2600R005ON" as an example to explain the typical coding logic (specifics may vary slightly by series):

"2600": Usually represents specifications related to filter size or flow capacity (adapted to different system flow demands).
"R": Stands for "Return Line", indicating the filter is specifically designed for the return line of hydraulic systems.
"005": Denotes the filtration accuracy, with the number representing the particle size (in μm) that the filter can effectively intercept. For example, "003" = 3μm, "010" = 10μm.
"ON": A model identifier used by Hydac, where different letter combinations correspond to variations in filter material, sealing type, or additional functional features (e.g., pressure resistance or compatibility with special fluids).

2. Technical Parameters

Parameter Category	Details
Filtration Accuracy	Ranges from 3μm to 100μm, matching the suffix in the model (e.g., 0750R020 = 20μm).
Filter Media	Mostly glass fiber (excellent filtration efficiency and large dirt-holding capacity); some models use sintered mesh or synthetic fibers for special working conditions (e.g., high temperature or corrosive fluids).
Operating Temperature	Generally -30℃ to +110℃ (suitable for most industrial hydraulic system temperature ranges).
Maximum Allowable Pressure Drop	Typically up to 20 bar (specific values may differ by model; consult the product manual for exact data).

3. Key Features

High Filtration Efficiency: Effectively removes impurities (e.g., metal shavings, wear debris, or dust) from hydraulic oil, maintaining oil cleanliness. This helps the system quickly reach and maintain the desired oil purity level, extending oil service life and reducing bearing wear.
Optimized Structural Design: Most models adopt a pleated filter element structure, which maximizes the filtration area within a limited installation space. This design improves filtration efficiency while reducing pressure loss.
Strong Adaptability: Compatible with common hydraulic fluids (e.g., mineral oil, synthetic oil) and suitable for harsh industrial environments (shock, vibration, or temperature fluctuations).

4. Application Fields

Hydac return line filters are widely used across various industries, especially in:

Metallurgical Industry (e.g., rolling mill hydraulic systems)
Automotive Industry (e.g., hydraulic control systems for production lines)
Power Equipment (e.g., hydraulic components in generators or turbines)
Chemical Industry (e.g., fluid control systems for chemical reactors)
Construction Machinery (e.g., hydraulic return lines in excavators or loaders)
Paper Industry (e.g., hydraulic systems for paper-making machines)
Shipbuilding Industry (e.g., marine hydraulic steering or lifting systems)
Machine Tool Manufacturing (e.g., hydraulic circuits in CNC machine tools)
