HCQ series vacuum degasser is a special-purpose device for the treatment of gas-cut drilling fluid. It is a new type one we have designed and developed by combining different sorts of degassers from home and abroad. It's applied to match various mud purification system. It is very important for returning mud gravity, stabilizing mud viscosity and reducing drilling cost. Also, at the same time it can be used as a heavy-power agitator during the operation of gas free mud.
