Foam Systems

As the fire service transitions to Synthetic Fluorine Free Foam (SFFF) concentrate, there are several concerns to be addressed. It is well known that the finished foam from these new formulas does not act in the same manner as Aqueous Film Forming Foams (AFFF). Formulation differences also mean that the viscosity of SFFF concentrates varies […]

“We’re trying to figure out what is the best and most cost effective setup for our foam system because the new Class A and Class B foam concentrate isn’t going through our current system. We’re looking at a foam eductor system, but our eductors are 40+ years old. I’m looking for an eductor that will […]

How Does a Firefighting Foam Eductor Work? In-line foam eductors work on the Venturi Principle. This principle uses extreme pressure loss inside the eductor to allow foam concentrate to flow up a pickup tube and into your water stream to create foam solution. How to Make the Best Quality Firefighting Foam Establish 200 PSI at […]

Are you considering foam eductors but wondering how to choose the right size and type for your crew? Let Brian “Pods” Podsiadlik walk you through a few considerations before you decide. What Should You Consider when Choosing a Foam Eductor? When you select your eductor and starting using it, you should confirm four things: Your […]

Are you wondering which of our nozzles can be used with alcohol resistant foams? Let Brian “Pods” Podsiadlik give you a brief explanation, including some information on the Bubblecup! What is the Bubblecup? Bubblecup is a firefighting nozzle that has a built-in foam aspirating feature. This feature allows you to slide a sleeve forward for […]

A key component of successful fireground application of compressed air foam is using a high-performance nozzle. Nozzle selection plays an important role in your fire department’s Compressed Air Foam System (CAFS) implementation program. During the nozzle selection process, buy-in from your firefighting teams on a final nozzle choice is challenging yet critical.   Today, nozzle selection […]

Nozzle Aspirated Foam Systems (NAFS)  To produce finished foam for application onto fire, four basic items are required: water, foam concentrate, air, and mechanical agitation. When all four components are brought together in the correct amounts, finished foam (the media applied to the fire or fuel surface) is produced. Nozzle Aspirated Foam Systems (NAFS) have […]

Most firefighters are familiar with nozzle aspirated foam systems (NAFS) and how they deliver foam to the fire. Another method of foam delivery is the compressed air foam system (CAFS). The following is a brief introduction to CAFS and how they work. Compressed Air Foam Systems (CAFS)  With a CAFS apparatus, there is no need […]

When evaluating nozzles for use with CAFS, there are four criteria that affect firefighter safety and firefighting efficiency. These are target delivery rate, finished foam quality, stream reach, and nozzle reaction force. Before we discuss each of these, let’s quickly discuss the use of Class A foam with a compressed air foam system. Class A […]
