What are you running for cord from the Smart power to the Super Vac's? Likely you've gone down this road already with the genset people.

Have you watched the webcast of Positive Pressure Attack? The link is located on the bottom of the home page, on the left hand side. The question that I would ask is; why electric fans?

I would suggest the reason they are using the electic PPV fans is to cut down on the noise and more importantly trying to reduce putting more CO into an already overloaded environment they are operating in like at a structure fire.

We have tried anything from a short heavy drop cord, using the cord real to plugging it in directly to the truck. Still surging. I understrand the longer the cord the more power we lose.
When we cut on the spot lights or put additional load on the generator, the surging stops. I understand about evening out the 2 output legs of the generator but looks like to me this would not be a problem, as big of a company as supervac is, I am sure someone else has run across this problem.

I have watched the webcast and I am a very big advocate for the gas powered fans. They will always have their place on the fire scene. We run these on the pumpers.
However, I feel electric fans do have their place. Such as food on the stove, high rise operations when only 1 apartment needs pressurizing etc.
We purchased these fans to go on the trucks so we would have one of each type on the scene. If we decide to use the gas powered fan we can take it off the pumper. If we need the electric fan, it is there too. Personally, I perfer ppv to smoke ejectors any day. But that is my opinion.

Thanks Brad,
An excellent response! Yes this is the reason. Your hit the nail on the head. But I am not worried as much about adding CO to a structure fire during the overhaul stage as we should be wearing our airpacks. But mostly during the routine food on the stove, highrise single apartment pressurizations etc. I feel both have their place and am glad we have convinced our Department of this instead of being closed minded to think one piece of equipment can do it all.
Like I said, my problem is the surging problems as originally stated.
Thanks again for having my back!
KJ

Brad, structure fires are putting out 1500 ppm of CO and the small engine is putting out 200 and something. Smoke ejectors are ok for a backed up fireplace, but there are few times where you can string a power line faster that you can pull a starter cord.
