What is a combination nozzle?
Combination Fire Nozzle Types The automatic, or constant pressure, nozzle is designed to maintain a relatively constant pressure over a wide range of flows. The multi-purpose nozzle is a combination solid bore and fog nozzle, providing maximum reach and heat absorption.
What is a fire nozzle?
Handline nozzles are one of the most important fire fighting gears for the firefighters to put out fires. A handline nozzle is connected to the fire hose that provides water flow to extinguish fires.
What is an automatic fire nozzle?
Conventional fog nozzles have a fixed or selectable gpm setting. With an automatic nozzle, the discharge orifice continually adjusts depending on the flow to the nozzle. This sets the flow being supplied to the proper nozzle pressure and correct velocity for maximum extinguishing capability.
What is a selectable Gallonage nozzle?
Protek’s Selectable Gallonage Nozzles are combination pattern nozzles with versatile multiple flow settings. The unique stainless steel teeth produce a wide range of patterns from straight stream to full fog. Inlet size is available in 1″ (25 mm), 1-1/2″ (38 mm) or 2-1/2″ (65 mm).
What is D class fire?
Class D fires involve combustible metals, such as magnesium, titanium, and sodium. Extinguishers with a D rating are designed to extinguish fires involving combustible metals. Note: Common extinguishing agents may react with a combustible metal fire causing the severity of the fire to increase.
How are electric monitor nozzles used in remote control?
Protek’s Electric Monitor Nozzles feature electrically operated pattern control for use in remote control applications. Flow pattern can be easily changed from solid bore to fog flow streams with a flick of the transmitter switch without shutting down.
What do you need to know about fire nozzles?
But it’s the nozzles at the end of each fire hose that make it possible for firefighters to safely and thoroughly extinguish a blaze. Nozzles, like hoses, need to be easy to use, durable, and right for the task at hand.
What is the pressure of a fire extinguisher nozzle?
For firefighting, more gallons of water available means more extinguishing agent to cool the fire’s fuel. Each nozzle has an expected, or rated, gallonage at a rated pressure. For example, a nozzle may deliver 60 GPM at 100 PSI, and 50 GPM at 110 PSI.
What’s the difference between constant and select fire hose nozzles?
While constant gallonage nozzles have a fixed orifice—and therefore one fixed discharge rate—constant/select gallonage spray nozzles allow firefighters to choose from one of several orifice sizes that guarantee consistent flow rates across all patterns. Automatic, or adjustable, nozzles can adjust to increases or decreases in flow.
