Nozzles, hoses and bottles are wear parts. Over time lines become porous, seals leak and nozzles clog. The tricky part: it is often only noticed when edge quality drops.
Warning signs
- uneven spray pattern or drops instead of a fine mist
- suddenly glue residue, chips or residue again at one position
- fluid leaking at fittings
- compressed air audible without fluid being delivered
What we recommend
- Regular visual check of the spray pattern, e.g. at shift change
- Monitoring with the Spray Monitor
- Complete overhaul instead of individual repairs when several components have aged: renew nozzles, hoses and bottles together
- After replacement, restore the position with the nozzle gauge

Replacing a nozzle – step by step
For the Ultra-Thin nozzle, first release the pressure at the CLOU®: simply open the cap on the CLOU®. Do not switch on the CLOU® while the fluid line is disconnected.
- Disconnect the air hose at the nozzle.
- Disconnect the fluid hose: when replacing the complete nozzle set, remove the hose upstream of the non-return valve. When replacing only the nozzle, remove the hose directly at the nozzle.
- Loosen the M10 nut on the nozzle and remove the nozzle.
- Fit the new nozzle or nozzle set in reverse order and reconnect the hoses.
- Align the nozzle to the workpiece using the matching nozzle gauge (premium two-substance nozzle or Ultra-Thin nozzle), then tighten the M10 nut.
