Flex attack Nozzle

HARRIS TOWNSHIP FIRE-RESCUE

Just as a reminder and to clear up any confusion, please read the following information on the new Flex Attack Nozzle.

As we know from our use of CAFS in the past, the only way to adjust the wetness of the foam is at the pump panel by adjusting the air/water mixture. This makes the wording on the Flex Attack misleading by labeling it: Water - Wet CAF - Dry CAF. CAFS as well as water can be flowed through any of these settings, what we are looking for is getting the most GPM out of the nozzle.

Discharge Orifice Size
Setting Size (inches)
Water 15/16"
Wet CAF 1 1/8"
Dry CAF 1 3/8"

Looking at the chart above we can see that the “Dry CAF” setting gives us the largest opening, which gives use the most GPM. The reason we went with this nozzle was to give us the ability to switch from CAFS to water without having to change a nozzle or takeoff/add a tip.

A better way to think of this nozzle is as an adjustable smoothbore nozzle. If you are looking for max GPM as you would for fire attack operations, you want to turn the tip to the Dry CAF setting giving you a 1 3/8” smoothbore. If you switch to water and you are not getting the reach you need, turn it to the Wet CAF or Water setting and decreasing the orifice size to a smaller smoothbore giving less GPM but more reach.

One last thing to remember we have preached for year “right for fight, left for lobster”, unfortunately this nozzle is the exception. The 1 3/8” (Dry CAF) setting is all the way to left on this nozzle and the 15/16” (water) setting is to the right. Please take time to do some training with this nozzle and become familiar with its operation. Do not let the first time you look at this equipment be when you need to use it in a real situation.
