Guidi System
Guidi System is a kit designed to grant the maximum safety of the hydraulic system of your boat. The system is developed to increase the performance of the water flow: it reduces pressure drops it avoids air bubbles and cavitation it grants an ideal and long-lasting working of the hydraulic systems on board. Guidi System is therefore essential for the boat. The kit consists of: water intake, non-stick valve, water strainer and fittings.
Water inlet "goccia"series
The drop profile, tuned by nature to minimize drag, has been adopted for the design of a new generation of water inlets. The shape has a continuous curve, with a distinct point for a maximum curvature, which ensures the bonding of the water flow to both the outside and inside of the water inlet, practically eliminating the formation of vortex and a reduction in turbulence.
