Eaton HDD 170-450 High Pressure Duplex Filter

For industrial applications requiring continuous operation and robust hydraulic filtration, the Eaton HDD 170-450 High Pressure Duplex Filter series stands out as a premier solution. Designed to handle demanding environments, this filter system ensures that your machinery remains protected from contaminants without requiring system shutdowns for maintenance.

As a distributor for top-tier filtration manufacturers, Purecowater is proud to offer the Eaton HDD series. This article provides a comprehensive look at the specifications, features, and operational benefits of the HDD 170-450 models.

Overview: Uninterrupted Hydraulic Filtration

The Eaton HDD 170-450 series consists of inline-mounted, high-pressure duplex filters capable of handling operating pressures up to 4,568 psi (315 bar). The defining feature of this series is the integrated change-over valve. This mechanism allows operators to switch filtration from one housing to the other, enabling the servicing of clogging elements without interrupting the flow of the hydraulic system.

This capability is critical for industries where downtime translates directly to significant financial loss. The HDD series is engineered with a high safety margin to absorb pressure peaks effectively, ensuring long-term reliability [eaton.com](https://www.eaton.com/us/en-us/catalog/filters-strainers/hdd.html).

Key Features and Benefits

Investing in the HDD 170-450 series brings several operational advantages to your facility:

• Zero Downtime Maintenance: The duplex design with a change-over valve enables filter element replacement while the system remains fully operational.
• High Intrinsic Stability: Built to withstand high pressure differentials and mechanical stress.
• Versatile Fluid Compatibility: Suitable for petroleum-based fluids, HW-emulsions, water glycols, and most synthetic lubrication fluids.
• High Dirt-Retaining Capacity: Maximizes the service life of filter elements, reducing the frequency of changes.
• Flexible Installation: Vertical installation position with accessible connections.
