With our customers driving, our machine is designed and manufactured by us based on our original GZ-5 machine. Besides holing all advantages of GZ-5 gunite machine, GZ-5A holds the additional new features: In worksites, only one compressed air hose is connected to the inlet of GZ-5A machine, the machine can work, without electric power supply. The output of machine can be Variable Speed from 2.5-5 cubic meter per hour(or from 3.3-6.6 cubic yards per hour) The GZ-5A can work in the explosion protection worksites.
