Product Overview

Description

 Fire fitting supplies brass foam water sprinkler head fire nozzle sprinkler manufacturer

The reticular foam nozzle (PTW series) is the specialized unit to form and spray air foam, which is mainly used in low expansion extinguishing system. Foam proportionate system supply foam solution for these nozzles. When foam solution was conveyed to nozzles by pipelines, the nozzle inhales air at outlet to make foams and put out fire.

Working Principle:

When pressurized foam solution flows through the cavity of the nozzle, its pressure will be reduced because of throttling. That will result in vacuum and inhale air. The foam solution then become foams after dispersed by nozzle.
