PJ - Misting spray nozzle
PJ misting nozzle atomises the liquid into a fine mist of fog, when the laminar jet impinges on the target pin.
The P and PJ misting nozzles create the finest fog of any direct pressure nozzles. For increased safety at high working pressures, the PJ nozzle can be supplied with a hole for attaching a safety cable.

Choose the right spray nozzle for an optimised spray process
Each type of nozzle has a specific flow rate, spray pattern and droplet size. To optimise the spray process, it is important to understand how different parameters affect the choice of spray nozzle and type of solution.
The Knowledge base contains information about spray pattern, droplet size, flow rate/pressure, spray coverage, materials, etc. The 'Materials' section of the Knowledge base lists the most commonly requested materials and maximum temperature of the material.
