VacOil™ Hydraulic Oil De-airing and Filling Stations

VacOil-1.5 Hydraulic Oil De-airing and Filling Station

APS’s VacOil™ systems are designed to separate and remove air, water, solvents, light petrocarbons and particulate contaminants from hydraulic oil with minimal operator intervention.

Applications include downhole drilling equipment and other hydraulic systems where dissolved gas can cause pump cavitation and particulates can clog passages, preventing valves from sealing properly.
