Combination Fire Nozzles
Smooth Bore Vs. Fog Nozzles: How to Determine if You Need a Combination Fire Nozzle
Smooth Bore Nozzles
Smooth bore nozzles, also known as solid bore nozzles, are the most basic type of fire nozzle - both in design and function. They produce a solid stream, providing maximum reach and penetration.
Fog Nozzles
Fog nozzles produce a similar stream to smooth bore nozzles, but require a higher inlet pressure. For example, the reach of a quality fog nozzle at 100 psi is about the same as a solid bore nozzle at 50 psi.
Fog nozzles are also designed to provide a dispersed stream - spinning teeth on the nozzle break up the water into smaller droplets for better heat absorption and steam effect.
Combination Nozzles
If you like the lower pressure performance of the solid bore nozzle and the pattern of the fog nozzle, consider a multi-purpose, or combination nozzle.
Combination Fire Nozzle Types
- Single Gallonage (Variable Pressure, Variable Flow) Nozzle
- Adjustable Gallonage Nozzle
- Automatic (Constant Pressure) Nozzle
- Multi-Purpose Nozzle (Combination Solid Bore, Fog)
The single gallonage nozzle is the simplest form of combination fire nozzles, providing flow at a predetermined rate that cannot be significantly altered while in use.
The adjustable gallonage nozzle allows the operator to manually select a desired gallonage while in use.
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. This versatile nozzle can produce large flows at reduced pressure and is well suited for multiple applications including interior, exterior, high-rise, CAFS systems, foam, cooling, protection and ventilation.

Combination Fire Nozzle FAQ
What kind of maintenance do combination fire nozzles require?
Under normal conditions, combination fire nozzles should periodically be flushed with clean, fresh water. Grit and dirt should also be removed from exterior moving parts to allow the nozzle to operate as designed.
It is also recommended that seals, o-rings and turbine teeth be inspected annually.
