Foam Eductors



Use with your Class A, Class B, & AR-AFFF Firefighting Foams

About the Foam Eductors

When you need a blanket of high-quality firefighting foam, you need reliable and easy-to-use equipment. Our foam eductors accurately proportion your foam concentrate at the selected setting, letting you focus on application and safety.  

What is a Firefighting Foam Eductor?  

An eductor is a piece of equipment that introduces foam concentrate into your water stream. In the device, water enters an inlet and moves through a tapered section. It then moves through a small orifice and into a bigger chamber to create a low-pressure area within the large chamber. A metering valve opens and the higher atmospheric pressure outside of the large chamber pushes your concentrate into the chamber. This concentrate then mixes with the water exiting from the lower pressure area, or Venturi.  

Once your water and concentrate mix, it is considered a foam solution. This solution then travels out of the tapered section at the end of your eductor for discharge.
