Technical Details for the GRM 503
The GRM 503 Mobile Filtration Unit provides a great method of oil care, equipped with the ICM 2.0 In-line Contamination Monitor. Boasting a powerful 50 L/min flow rate and continuous operation at 3.5 bar, it excels in filling and filtering hydraulic fluids and lubrication tanks. Connectable off-line to tanks (recommended max volume 1000 L), it supports fast flushing during start-up and acts as additional filtration for highly contaminated systems. Portable and easy to set up, it includes an electric control box with a pressure safety switch, indicators, and real-time monitoring with data logging capabilities. The GRM 503, with water removal option, is the epitome of advanced oil care.
Designed and manufactured by MP Filtri, these trolleys are a great asset to have around your hydraulic systems as they offer a great way of filtering fluids as you fill your tank.
