According to the construction specifications of the German Armed Forces for naval ships, 0.24 m 3 /h (4 l/min) is required per m 2 of deck area. However, it was possible to prove in tests that 2.5–3.0 l/min is sufficient for coverage of the deck surfaces due to the low spray losses of the Lechler nozzles used when com- bined.

Deflector-plate nozzlesSeries 571/500.289
Applications: Cleaning deck surfaces in the event of NBC contamination.
�� Series 571 Modular-design deflector- plate nozzle where the nozzle is guided. This allows simple mounting/disassembly, e. g. for cleaning purposes or in areas with high mechanical loads (e. g. in the area of the guns).
�� Series 500.289 Deflector-plate nozzle for mounting using stud bolts and clamp couplings (e. g. Straub Grip-L) from the inside of the ship.
