Audited Supplier Foam Sprinkler, Foam Nozzle Series
The reticular foam nozzle (PTW series) and foam and water dual sprinkler (PTT/S series) are the specialized units to form and spray air foam, which is mainly used in low expansion extinguishing system. The foam solution conveyed to the nozzle by pipes and inhale air before outlet of the nozzle and then become foams to put out fire. The foam/water combined nozzle can also spray water besides spraying foam.
Working principle:
When the pressure foam solution flow through the lumen of the nozzle, its pressure will be reduced because of throttling, which result in vacuum and inhale air. The foam solution then becomes foams after dispersed by nozzle.
