The OpDSH VFix nozzles are fixed area spraying devices, single or multiple, with excellent atomizing characteristic due to a sophisticated internal vortex ring which ensures very small water droplet size at low differential pressures.

They are primarily intended for applications where load is nearly constant but moderate load fluctuations can be controlled with guaranteed rangeability. Maximum care is taken to keep the angle of the spray cone narrow in order to minimize the impact of water against the internal pipe wall.
