The A2111-0000 system is designed to refill hydraulic oil systems and cooling systems of fixed- and rotary-wing aircraft. The refilling car body accomodates three fluid tanks and a pneumatic system to create surplus pressure in the tanks.

The refiller can be custom-fitted with various combinations of fluid tanks. The tanks are easily demountable, and can be used independently from the refiller. The refiller uses the AMG-10 and 7-50s-3 hydraulic fluids, mineral and synthetic oils, and antifreeze coolant pressurized to 0.2-0.55 MPa. Both open and closed refilling is possible.
