Connected By-Pass Units

The RMF By-Pass Units are especially designed for mobile application in hydraulic and/or transmission systems. RMF By-pass filter units can be fitted to every imaginable mobile application where hydraulic and/or transmission systems are present.

Connected By-Pass Units enable machine operators to keep their hydraulic oil clean and monitor contamination levels real-time in one economical installation. They can be easily mounted to new and existing installations, and combine all advantages of By-Pass filters and Contamination Monitoring Sensors.

Features

The By-pass filter comes equipped with an integrated pressure compensated flow control valve. This valve bleeds oil from the main hydraulic system, passes this through the filter after which it is returned to the hydraulic reservoir. The amount of oil extracted from the main system at any time is insignificant ensuring that it will not affect the working of the main system. Most commonly used biodegradable oils in the mobile sector are suitable for filtration with RMF filter elements.

RMF By-pass filter units can be fitted to every imaginable mobile application where hydraulic and/or transmission systems are present.
