Bosch Rexroth has 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 Filter Select sizing software can be used to quickly determine the best filter for a specific hydraulic application and will provide Rexroth’s part numbers, model codes, pressure drop curves, dirt holding capacities, spare parts, and more.

At the core 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 Filter Select.

Bosch Rexroth said the Filter Select program now includes hydraulic fluids from Houghton International. The company said the decision to add Houghton fluids to the program was based on recent testing that demonstrated Houghton’s hydraulic fluids would deliver the performance required by Bosch Rexroth components.

The company pointed out that effective hydraulic fluid performance and filtration can significantly improve the performance, longevity and efficient operation of hydraulic systems. For best results in actual practice, the customer must maintain the fluid and monitor with regular testing.
