The Eaton HDD 901: reliable High-Pressure Duplex Filtration
For industrial hydraulic and lubrication systems operating under high pressure, maintaining fluid cleanliness without interrupting operations is critical. The Eaton HDD 901 is a high-performance duplex pressure filter designed specifically for these demanding applications. Part of Eaton’s renowned HDD series, this unit allows for continuous filtration even during maintenance, ensuring your machinery stays protected and productive.
As a distributor for premium filtration solutions, Purecowater provides access to the full range of Eaton hydraulic filters. Below, we detail the capabilities, specifications, and applications of the HDD 901 to help you determine if it is the right solution for your system.
What is the Eaton HDD 901?
The Eaton HDD 901 is a duplex high-pressure filter. Unlike simplex filters that require a system shutdown to change clogged elements, the HDD 901 features two filter housings connected by a change-over valve. This design allows operators to switch the flow from the dirty filter chamber to the clean one without stopping the system flow or dropping pressure significantly.
Designed for working pressures up to 4,568 PSI (315 bar), the HDD 901 is engineered to handle substantial pressure peaks with a sufficient safety margin, making it ideal for heavy-duty hydraulic circuits.
Key Features and Benefits
- Continuous Operation: The integrated change-over valve allows for element replacement while the system remains live (24/7 operation).
- High Pressure Capability: Rated for operating pressures up to 315 bar, suitable for high-stress hydraulic lines.
- Robust Construction: Built with high-grade materials like EN-GJS-400-18-LT and carbon steel to withstand harsh industrial environments.
- Versatile Fluid Compatibility: Suitable for petroleum-based fluids, HW-emulsions, water glycols, and most synthetic lubrication fluids.
- Direction of Flow: Fluid flows from outside to inside, maximizing the dirt-retaining capacity of the filter elements.
