The Department currently utilizes Task Force Tips (TFT) Nozzles on all 1 3/4" and 2 1/2" attack lines along with the TFT Blitzfire being the ground monitor on every apparatus. Currently, all PFD apparatus with pumping capabilities have two 200' 1 3/4" crosslays and one 100' 1 3/4" bumper line with TFT CAFS Force 1 fog nozzle tips, one 200' 2 1/2" crosslay with a TFT Smooth Bore 1 3/16″ straight tip.
1 3/4" Handline
1 3/4" Handline
1 3/4" attack lines equipped on all PFD pumping capable apparatus have TFT CAFS Force 1 dual pressure nozzle tips capable of 70 - 200 GPM with a standard pressure of 75 PSI in Water and a low pressure of 45 PSI in CAFS. All 1 3/4" nozzles feature an internal orifice diameter of 15/16" and 1 1/2" inlet and outlet couplings.
What is the CAFS-Force Nozzle?
What is the CAFS-Force Nozzle?
The CAFS-Force Nozzle is a firefighting nozzle designed specifically for Compressed Air Foam Systems (CAFS) and water applications. The nozzle is engineered to provide optimal foam stream performance and low-pressure nozzle operations when using water alone.
Handheld Nozzle
This tip only nozzles require a ball valve shut off and features:
Automatic dual-pressure control
Flow capacity: 70-200 GPM (265- 760 LPM) or 95-250 GPM (360-950 LPM)
Molded rubber pumper with power flog teeth
Flush without shutting down

CAFSForce1Instructions.pdf2 1/2" Handline
2 1/2" Handline
2 1/2" attack lines are equipped with TFT Smooth Bore nozzle tips capable of the following:
265 GPM @ 40 PSI
296 GPM @ 50 PSI
324 GPM @ 60 PSI
All 2 1/2" nozzles feature an internal orifice diameter of 1 3/16" and a 2 1/2" inlet coupling and a 1 1/2" outlet coupling.
Smooth Bore Advantages and Disadvantages
Smooth Bore Advantages and Disadvantages
Every nozzle has pros and cons associated with it. Here are a few for smooth bore nozzles:
Pros
Smooth bore firefighting nozzles are simple and have a no-frills design.
You can achieve good flow, reach, and penetration even with lower pump pressures.
Since the nozzle does not have any selection dials you cannot accidentally move into a fog pattern.
Cons
The Smooth bore does not have a fog or broken pattern option. This means you would need to gate the nozzle to achieve a broken pattern, which lowers your flow rate.
These nozzles can be over or under pumped which will affect your reach and nozzle reaction.
The water is shaped by the waterway and exit orifice. If either is damaged or scratched, you may experience turbulence and lose your stream quality.
If you find yourself in need of more GPM, you cannot choose another option on your nozzle. You need to shut down the line and replace your tip first.
Blitzfire
Blitzfire
The TFT Blitzfire is the ground monitor equipped on all PFD pumping capable apparatus. It features both a TFT Max-Force fog nozzle tip and a set of TFT Smooth Bore stacked tips. The Blitzfire has 2 1/2" inlet and outlet couplings with a maximum flow of 500 GPM. Due to the Blitzfire having 2 1/2" couplings 3" or 2 1/2" hose can be used to supply this application.

The Blitzfire is equipped with a Safety Shut-Off Valve. The Safety Shut-Off Valve will shut off the monitor’s flow if the monitor starts to move. The Safety Shut-Off Valve relies on acceleration of the Blitzfire as the signal to activate. It activates at approximately one G of sideways acceleration. Placing the Blitzfire on tilted surfaces (greater than 10 degrees) may inhibit the resetting of the Safety Shut-Off Valve. The hose connected to the Blitzfire should contain any forward or backward motion to safe levels.
Stacked Tips
Stacked Tips
The TFT Smooth Bore stacked tips allow the Blitzfire additional penetration capabilities compared to the fog nozzle. The maximum pressure with stacked tips is 175 PSI.
Fog Nozzle
Fog Nozzle
The TFT Max-Force fog nozzle tip is equipped on all Blitzfire ground monitors in the PFD inventory. The benefit of this tip is the adjustable stream in addition to increased flow.
