No matter what oil you use in your machines, it will eventually become contaminated. The full-flow filters normally installed in hydraulic systems can only filter out the larger particles, while smaller particles along with water, oxides, and sludge continue to circulate in the system.
The consequences are increased wear, poorer performance, and reduced reliability. Filters become clogged, and exposed components risk seizing or failing. Water, heat, air, and contaminants in combination with synthetic esters (environmentally friendly oils) initiate the oil degradation process already in the hydraulic tank.
There are several advantages:
- Significantly extended service and oil change intervals
- Drastic reduction in oil leakage, repair, and downtime costs
- Increased performance, controllability, system efficiency, and reliability
- Longer lifespan for the machine and its components
ROVAB works with two types of filtration
Filtration of the oil tank's breather air.
The breather air is purified and dehumidified through a breather ventilator containing a particle filter and a water-absorbing material. Used, among other things, on oil and fuel tanks, gearboxes, and transformers.
Deep-filtering “Bypass and Offline filters”
The oil circulates through a very fine filter that is either connected directly to the existing hydraulic system or, together with an external pump, connected to the oil tank. The oil is purified from large down to small microparticles, water, sludge, and oxides that a full-flow filter cannot purify.
