    Default CFX CAFS systems

    Has anybody used the CFX CAFS systems before? That is a realy interesting pump design.

    Here are the CAFS units:

    And here is the CEM ( Cylindrical Energy Module) pump:

    I am sure they work, but what I am wondering about is:

    - Durability
    - Endurance of the 12 volt systems? Would they drain your vehicle?

    Also, how would you recirculate something like this? I have never worked around a positive displacement pump/piston pump. You have to criculate unless you are flowing water, right? So how would that work with this unit?

    Would you get foam in your tank, or does the foam come in after the recirc valve?

    Anybody ever use one of these?

    Experiences?

    Heard anything good or bad?

    One of the big benefits of this system seems to be the cost/performance ratio.

    For example, we just retrofitted our old BLM type 3 heavy wildland unit. It was a BLM designed CAFS system before with 2 motors and an air compressor 1.5 times the size of a VW bug engine! It was loud, complex, worn out, and not user friednly.

    We put a Odin foam Colt II on it:

    http://www.odinfoam.com/coltII/coltii.htm

    29 HP Kawasaki gas engine
    Dimensions
    Length 30” (76.2cm)
    Width 46” (116.84cm)
    Height 28” (71.12cm)
    Weight 595 lbs. (269.9kg)

    Performance
    Water Pump 140 GPM @125 PSI
    Air Compressor 60 CFM @ 125 PSI
    Simultaneous Flow (NFPA) 80 GPM & 40 CFM @ 125 PSI
    Simultaneous Flow 90 GPM & 45 CFM @ 100 PSI

    25,530.00$ without options.

    This system is awsome for wildland and initial attacking other types of fire. While it doent flow all that much, it realy packs a punch when you crack the 1.5 with a smooth bore at max capacity. User friendly, smooth running, and sharp looking.

    Now, compare this to the similar CFX units, one is similar in performance, the other similar in price.

    A much smaller unit, with a much smaller price. Similar perfomance on paper. I wonder if it could hang with the Colt II in real world???

    Still much smaller then the Colt II, great weight savings. Higher performance on paper. Cost is still a few grand less then the Colt II. I like the option for the diesel engine. We could have plumped it right into the main truck tanks.

    So, now in retrospect, I wish we would have taken a look the CFX Magnum CAFS. It gives higher performance then the Colt II, weights less/smaller, and diesel.

    I am still worried about the CEM durability, ability to handle dirtier water, and endurance, can it pump for hours on end?

    We didnt even know about the CFX CAFS until long after the Odin Foam Colt II was ordered. I think I am developing buyers remorse...
