Execution:

  • made in accordance with PN-EN-671-1
  • nozzle with valve plastic head
  • regulation of the stream type and efficiency takes place by turning the gripping part of the nozzle made of ABS plastic in red RAL 3000

Nozzles allow you to adjust the settings in the following positions:

  • closed
  • dispersed water stream
  • compact water stream
