The different between single venturi and double venturi nozzle
Single venturi nozzle is the long range type, one air inlet.
Double venturi belongs to high speed type, with eight holes around the shell, due to the high speed air flow, the speed of air ejecting faster than compressed air, speed of blasting is higher.
