Frontier Automatic Fire Monitor Nozzle – 50–350 GPM
Automatic Pressure-Regulating | Straight Stream & Fog | 100 PSI
Product Overview
The Frontier Automatic Fire Monitor Nozzle delivers dependable firefighting performance across a wide range of water flows. Designed for use with compatible portable and permanently mounted fire monitors, this versatile nozzle provides excellent stream quality, effective water distribution, and convenient adjustment between straight stream and fog patterns.
Unlike conventional fixed-flow nozzles, the Frontier Automatic Monitor Nozzle automatically adjusts its internal discharge opening in response to changes in water flow. This helps maintain a consistent operating pressure and effective stream performance throughout its rated flow range.
Operating at 50–350 GPM (190–1,325 LPM) with a nominal nozzle pressure of 100 PSI (7 BAR), the Frontier Automatic Nozzle is suitable for municipal fire departments, industrial firefighting, equipment cooling, and exposure protection.
Its rugged aluminum construction, corrosion-resistant Nituff finish, stainless steel stream shaper, and spinning fog teeth provide durability and dependable performance in demanding firefighting environments.
How an Automatic Monitor Nozzle Works
An automatic monitor nozzle is designed to maintain a relatively consistent nozzle operating pressure while accommodating changes in the volume of water being supplied.
Inside the nozzle is a pressure-responsive mechanism that automatically adjusts the size of the discharge opening.
When water flow increases: The internal mechanism opens the discharge passage to accommodate additional water while helping maintain the nozzle's designed operating pressure.
When water flow decreases: The mechanism reduces the discharge opening to help preserve nozzle pressure and stream quality at the lower flow rate.
This automatic adjustment provides several important advantages:
- Improved stream consistency: Helps maintain effective stream reach and performance as water flow changes.
- Flexible water supply requirements: Accommodates different available water flows within the nozzle's rated operating range.
- Reduced need to change nozzle tips: One automatic nozzle can accommodate a wide range of flows without replacing fixed-flow tips.
- Efficient firefighting operation: Allows firefighters to concentrate on directing the water stream and adjusting the pattern.
Important: An automatic nozzle does not increase the available water pressure or create additional water flow. Its pressure-regulating mechanism operates within the limits of the available water supply and the nozzle's designed performance range.
The nozzle is designed for optimum performance at 100 PSI (7 BAR), although it can provide useful firefighting performance at pressures as low as 50 PSI (3.5 BAR). Performance at reduced pressure will depend on available flow and operating conditions.
Key Features & Benefits
- Automatic pressure regulation: Automatically adjusts the discharge opening to help maintain consistent operating pressure across a flow range of 50–350 GPM.
- Straight stream and fog capability: Quickly changes from a concentrated straight stream to a wide fog pattern with a quarter-turn adjustment.
- Excellent stream quality: Integrated stainless steel stream shaper helps produce a well-defined stream for effective water delivery.
- Wide fog coverage: Stainless steel spinning teeth produce a uniform fog pattern for cooling, exposure protection, and broad water distribution.
- High-strength aluminum construction: Provides durability without excessive weight.
- Nituff protective finish: 50-micron PTFE-impregnated hard-anodized coating offers excellent corrosion and wear resistance.
- Convenient flushing: Allows debris to be flushed without shutting down the water supply or changing the selected stream pattern.
- Multiple thread configurations: Available with BAT, CSA, NHT, WCT, and NFL connections to suit different monitor installations.
- Low-pressure capability: Provides useful performance at pressures as low as 50 PSI, subject to operating conditions.
Typical Firefighting Applications
Portable Fire Monitors
Ideal for portable ground monitors used by municipal fire departments, industrial fire brigades, and emergency response teams.
The automatic nozzle accommodates varying available water flows, helping maintain effective stream performance when operating from different pump capacities, hydrant supplies, or water delivery systems.
Permanently Mounted Fire Monitors
Suitable for fixed monitor installations where reliable, directed water delivery is required.
Applications include industrial facilities, equipment protection, storage yards, loading areas, and other locations requiring dedicated firefighting water streams.
Industrial Firefighting and Exposure Protection
The combination of straight stream and fog patterns provides flexibility for equipment cooling, exposure protection, and general industrial firefighting operations.
Municipal Fire Departments
Provides an adaptable solution for fire departments using monitors under different water supply conditions, reducing the need to change fixed-flow nozzle tips when operating requirements vary.
Fire Monitor Compatibility & Installation
The Frontier Automatic Fire Monitor Nozzle is designed for installation on compatible portable or permanently mounted fire monitors.
Before installation, verify the following:
- Connection size: The monitor outlet must match the nozzle's 65 mm (2.5 in.) nominal connection size.
- Thread compatibility: Select the correct BAT, CSA, NHT, WCT, or NFL thread configuration. Similar connection sizes do not necessarily mean threads are interchangeable.
- Monitor flow rating: The monitor must be rated to safely handle the intended operating flow, up to 350 GPM.
- Monitor pressure rating: The monitor and associated equipment must be suitable for the operating pressure and system conditions.
- Water supply capacity: The pump, hose, piping, and water source must provide sufficient flow and pressure for the intended application.
- Mounting stability: Portable monitors must be properly secured and operated according to the monitor manufacturer's instructions. Permanently mounted monitors require adequate mounting support.
Important: This nozzle does not independently control water flow or provide a shut-off function. Flow control and shut-off must be provided by the monitor or associated water supply equipment.

NFPA Standard Conformity
The Frontier Automatic Fire Monitor Nozzle is manufactured to meet the applicable requirements of NFPA 1964, 2008 edition, covering spray nozzles, shut-off devices, and tips.
This is a manufacturer-stated conformity claim. The nozzle has not been independently certified by a third-party certification organization.
Why Choose the Frontier Automatic Monitor Nozzle?
Firefighting operations do not always have access to the same water flow or supply conditions.
A conventional fixed-flow nozzle is designed around a specific flow and pressure. When the available water supply changes, nozzle performance can be affected.
The Frontier Automatic Monitor Nozzle provides greater operational flexibility by automatically adjusting its discharge opening to accommodate changes in flow while helping maintain effective stream pressure.
Combined with durable construction, straight stream and fog capability, and multiple connection options, it offers a practical solution for fire departments and industrial users seeking versatile monitor nozzle performance.
