Can an automatic nozzle be used with foam and foam eductors?
If the eductor manufacturer's recommendations for inlet pressure, maximum hose length and size are followed, the automatic nozzle will adjust itself automatically to the rating of the eductor. With any eductor system, the nozzle valve must be fully open to prevent excessive back pressure on the eductor, which will prevent foam concentrate pickup.
Certain guidelines, however, must be followed. Foam-making is simply the addition of a proper amount of foam concentrate to water. This solution of foam concentrate and water is then mixed with air (aeration) either at the nozzle with aspirating attachments or as the stream pulls air along with it in a non-aspirating application.
