Pneumatic Fluid Separator VIST
VIST is especially designed for the drilling cuttings drying with shale shaker in oil and gas drilling, through the last shaker screen to effectively dry the discharged cuttings, and achieve the goal of reducing waste and reusing drilling fluids.
This system is a completely pneumatic system, without any electrical elements, and can be widely used for OBM, SBM and WBM for onshore and offshore drilling.

Technical Features of VIST
- Widely used for OBM, SBM and WBM.
- To replace the drying shaker without additional consumption of screens. Less footprint and easy installation without welding.
- Reduce waste by 30% to 50%. A finer screen can be used to improve solids control.
- Less cost for transporting drill cuttings.
- No need for electric power, suitable for use in hazardous areas.
- Suction and discharge times are adjusted according to drilling conditions.
