How Does Your Firefighting Nozzle Affect Impact Force?

In the fire service, it is often believed that a smoothbore has the highest impact force or that it is the hardest hitting nozzle. You may love a good smooth bore, but did you know that impact force doesn’t actually depend on the type of nozzle?   Which Firefighting Nozzle Has the Highest Impact Force?  […]

How Does Nozzle Pressure Affect Stream Velocity?

What is Nozzle Flow Pressure?  Nozzle flow pressure is the discharge pressure of a nozzle at a given flow rate. It is an indication of the velocity flow of your fire stream in feet per second. You can use the hydraulic formula for velocity flow for any smooth bore, fixed, selectable, or automatic firefighting nozzle. […]

What type of firefighting nozzle hits hardest?

We’ve engineered a testing method to accurately measure the impact of a fire stream and has answered the question – Which nozzles hit hardest? “A fire stream can be defined as a stream of water or other extinguishing agent after it leaves the fire hose and nozzle until it reaches the desired point. During the time a […]

What is the best firefighting nozzle?

With hundreds of models of handheld fire hose nozzles from which to choose, the choice can be confusing and the decision making process often frustrating. Before investigating which nozzle may be an ideal choice for initial attack fire flow operations, one basic factor  must be considered before all others: Determining the agency’s target fire flow will be critical to the overall […]

How Does an Automatic Firefighting Nozzle Work?

Sketched on a napkin in 1968, the automatic fire nozzle is the youngest nozzle type you’ll encounter in the fire service. So, how do they work and what makes them “automatic?” Let’s find out! What is an Automatic Firefighting Nozzle?   An automatic nozzle is a variable flow, constant pressure firefighting nozzle. This means that […]

How Does a Selectable Firefighting Nozzle Work?

How Does a Selectable Firefighting Nozzle Work? A selectable nozzle allows you to change your flow rate on the fire ground without changing tips. In this video, you will learn more about how these nozzles work, how they relate to smooth bore tip sizes, and what happens if you change your GPM selection without communicating with […]

What is a Fixed Flow Firefighting Nozzle and How Does it Work?

What is a Fixed Flow Nozzle?  A fixed gallonage nozzle is a firefighting nozzle that provides a constant flow rate or gallonage and can flow a straight stream or fog pattern. These nozzles come in a range of pressure choices so that you can choose the option that is right for your fire department. How […]
