Manual nozzles have been designed to satisfy the need of safety, ease of handling and efficiency. The nozzles are manufactured with a resistant aluminium body enclosed in an anti-shock plastic shell which increases the nozzles ease of handling by making the grip comfortable even when working at low temperatures. The integrated swivel connector, and the hammer free valve inside it, guarantees a high degree of safety. The low loss of head, given the conformation of the valve, allos it to function at upto 150 L/min.
