The nozzles are constructed of natural PVDF - a super-tough, chemical-resistant fluoropolymer. Because no colorants or fillings have been added to the PVDF spray nozzles, they are especially suitable for such ultra-pure processing environments as electronics. Capable of spraying a variety of chloride, acid, alkali, and ammonia-based etchants, the nozzles can withstand temperatures up to 149°C at 7 bar. Models of the FullJet® and VeeJet® spray nozzles are also available with a removable strainer. The strainer guards against wear of the nozzle caused by liquid-carried foreign matter. This makes the nozzle a particularly good choice for a variety of general industrial applications.
