Protection Class

Protection class IP69K has been created for high pressure and high temperature cleaning

according to DIN 40050-9. Code “6” (Dust tight. No ingress of dust.) defines the protection

against solids. Code “9K” (Protected against close-range high pressure, high temperature spray

downs.) defines the protection against liquids.
