Venturi kit for use with a high-pressure fire-fighter. The kit includes a 3m suction hose, aluminium venturi head and a male quick connect to couple the kit to the hydraulic hose. The venturi kit is a novel and practical way to fill your fire-fighter tank using the high-pressure fire-fighter. By connecting the 20m sprayer hose to the male connector on the venturi head, and submerging the head under water, you can syphon/suck water into the tank. You would typically use the venturi kit to fil la tank from a water source such as a river or pool. A 600L tank can be filled in 3 minutes using the venturi kit.
