Foam nozzles for non CAFS applications

[mohican]

What nozzled do you fine people use for foam application, and why

We're retrofitting an auto, pressure side foam system (either foam pro or Hale) to our front line engine, and want to investigate different types of nozzles.

We've been using the same type of system you are talking about for 4 years and the only nozzles we have ever used are automatics. We use TFT and Akrons. We have both class-A and B foam tanks and the couple of times we used the B foam (for minor gasoline spills at auto accidents to simply suppress vapors) the automatics set at a narrow fog pattern gave us a 3" blanket. We've been also using a narrow fog pattern on the A side also during fire suppression which gives a "drippy" half inch coating of foam on all interior surfaces while knocking the fire down. You'll be surprised, once you spray the white stuff on what ever is burning it's out for good.

We've always used a combo nozzle for straight class A, but used to carry aspirators which fit on the nozzle if we wanted high volume foam. Now we have CAFS on our main truck so we don't carry the aspirators. I've always wanted to try a vindicator nozzle with Class A, heard it makes foam nearly as good as the CAFS.

Has anyone tried the long tube type nozzles like BlizardWizard? Do they give you more "reach" for exterior or wildland applications?

We use the "Bubble Jet" 95gpm fog nozzle with a external foam inductor. Key points are to set % correctly and make sure the bail is open fully to pull the foam out of the bucket. Good luck

anyone using the vindicator in conjunction with foam?

At out department we have the 2000 edition foam pro system. we us elkhart sm-30fnozzles, they are 100 psi automatic nozzles. We use these with our foam lines for the purpose that we do not want to loose our gpm while attacking a fire. Some fire departments that use caf's (not all) lower their psi which in turns lowers their GPM. So we use the combo nozzle that is capable of flowing from ranges of 75 to 325 gpm, and if we want a thicker application we would increase the percent of flow (using more foam though $$$) without loosing the gpm. Then for our class b application we have an elkhart adapter that attached to a nozzle to help induce air into the foam.
The elkhart nozzles are good. good luck with what ever you choose.

We use The Akron turbojet on our 1 3/4 hand lines that are running either our A foam or B foam from a foam pro system. We also have an aspirator to attach if we should choose. Has worked out for us the last 3 years with good results so far.

We use Heavy Attack Vindicator nozzles with foam. They seem to work very well.
