The RH foam nozzles were designed to work on the Venturi principle.
A stream of foam solution is sprayed at high speed against an outlet net, drawing into the body the air required and producing foam with an expansion ratio of about 1:20.
Their high reliability makes them very dependable on critical applications such as truck loading areas of the oil industry.
