Fault Elimination - Storch Duomax 9000 Mode D'emploi

6. Selection of airless nozzles
Selection of nozzles is governed by borehole and width of spray. Purposeful selection is determined by the spray width
required for a specific work procedure and the borehole for delivery of the desired quantity at optimum atomization.
Small boreholes with thin material and large boreholes with viscous material is a generally valid rule.
Below are the most used sizes for various materials.
Please note:
The maximum nozzle sizes recommended for the airless device used must not be exceeded.
