Bosch Rexroth’s Filter Select tool quickly determines the best filter for hydraulic applications

Filter Select

The Filter Select tool calculates pressure drop across Rexroth filters based on various user inputs

Bosch Rexroth developed a filter sizing program that allows users to input various parameters such as fluid type, fluid viscosity, system temperature, and micron rating to evaluate the pressure drop across Rexroth filters. The sizing software (Filter Select) can be used to quickly determine the best filter for a specific hydraulic application and will provide Rexroth part numbers, model codes, pressure drop curves, dirt holding capacities, spare parts and related components.

With the Filter Select program, users can quickly choose and document the proper filter size and type for hydraulic applications. Highlighted features of Filter Select include:

• Calculate total pressure drop through the filter housing and element

• Define the replacement element, seal kit and other filter accessories

• Determine the dirt holding capacity

• Estimate the system pressure impact of changing fluid parameters such as fluid temperature, viscosity or changing main pump flow

• Prevent incorrect model code formulations

• Selects the proper Rexroth filter size for industrial and mobile hydraulic applications

• Determine the fluid viscosity at any temperature for any fluids loaded in the program

At the heart of the Filter Select program is a database of hydraulic fluid information. With close cooperation between several fluid manufacturers, an extensive fluid library has been developed and loaded into the software. Additionally, Filter Select allows users to modify the clean pressure drop target which allows a customized solution for almost any application. Once all the necessary information is input into the tool, it provides the Bosch Rexroth part number and model codes for the recommended, properly-sized filter, as well as alternatives that can be chosen based on each individual case. Once done, users can choose to generate a PDF application form that documents the parameters used to determine the exact Bosch Rexroth filter solution.
