Product Description
The RFA series miniature direct return oil filter is a high-efficiency component designed to filter contaminants from hydraulic fluid as it returns to the reservoir, thereby protecting the system and extending fluid life. It is known for its compact structure, high filtration accuracy, and ease of maintenance.
Key Features of RFA series miniature direct return oil filters
High Filtration Efficiency: The filter element mainly uses glass fiber material, offering advantages such as high filtration accuracy, low initial pressure drop, and high dirt-holding capacity. Filtration accuracy options include 1, 3, 5, 10, 20, and 30 microns.
Safety and Reliability:
Bypass Valve: When the filter element is clogged or the oil temperature is too low, the bypass valve will automatically open (usually at 0.4 MPa pressure) to protect the safe operation of the hydraulic system.
Contamination Indicator: Equipped with a visual or electrical indicator that signals when the pressure difference reaches a set value (e.g., 0.35 MPa), prompting filter element replacement.
Structure and Installation: Adopts a direct return installation design, directly mounted on the oil tank cover plate, with the filter head exposed outside the oil tank for easy filter element replacement and oil filling.
Fluid Diffuser: A fluid diffuser is located at the bottom to ensure smooth oil return to the tank, reducing air re-entry and bubble formation.
Simplified System Piping: The integrated design simplifies system piping connections, resulting in a more compact system layout.
Application
Engineering and Mining: Protecting the hydraulic systems of heavy equipment such as excavators, bulldozers, and cranes.
Manufacturing: Ensuring the purity of fluids in precision machinery such as CNC machine tools, injection molding machines, and robots.
Oil and Gas: Used in drilling platforms and pipeline control systems to withstand contaminants in harsh environments.
Aerospace: Used in ground support equipment and maintenance systems to ensure hydraulic fluid meets stringent cleanliness standards.
Agriculture: Protecting the hydraulic systems of agricultural machinery such as tractors and combine harvesters.
Power Generation: Used in wind turbines and other power plant auxiliary systems.
Marine and Transportation: Protecting the hydraulic steering systems of ships and the braking systems of trains and trucks.
Filter are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
All Filter are manufactured in compliance with international standards, ensuring high performance and reliability:
ISO 9001: Certified for quality management systems.
CE Certification: Ensures compliance with European safety, health, and environmental protection standards.
RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.

The Green hydraulic pump manufacturing facility is a specialized industrial plant that focuses on producing hydraulic pumps and related components. These factories are equipped with advanced machinery and technology to fabricate high-quality pumps designed for a wide range of applications, from heavy equipment and machinery to automotive and industrial systems.
The production process typically involves precision engineering, where raw materials like metals and alloys are processed into pump components such as gears, pistons, cylinders, and seals. These parts are then assembled into fully functional hydraulic pumps, which are tested for performance and quality control to ensure reliability, efficiency, and durability under various working conditions.
All hydraulic pumps produced by Green Hydraulic have undergone compliance testing, ensuring their quality and reliability.
To meet the diverse needs of different industries, the green hydraulic offer customization options, such as specialized seals, materials, and pump configurations. These facilities often work closely with engineering teams to develop tailored solutions for specific applications, from high-pressure systems to low-flow, high-efficiency pumps.
