K17 ESFR Pendent Sprinkler

It is an ESFR pendent sprinkler head with K17 flow coefficient. It is preferred in installations where storage height is at a medium level and the water supply required by a K25-class head cannot be provided. In ESFR selection, the determining factor is not only the sprinkler head itself, but whether the pump and reservoir can supply the flow rate required by that head.
