EXP inflatable separators

Pronal EXP inflatable separators protect the oil used in protective applications from dust and damp by compensating for variations in volume. The latter may cause deterioration to the characteristics of the oil and components forming the hydraulic system. Compensation bladders are permanently installed in the system so that it is independent and maintenance-free.

These inflatable separators are available in standard models but can also be made to measure to match the dimensions of your tanks and the volumes to be compensated for. True auxiliary tanks, they can be located inside or outside of the tank and can be made flat or with a given shape.
