    Question Class A Pumper, and CAFS

    I have two questions and I am not sure if this is the right forum, forgive me if it is not.

    1) Does anybody know what booster tank size is needed for a "Class A" pumper according to NFPA?

    2) What percentage of foam concentrate does a CAFS require?

    Thanks in advance

    To your questions;
    1.) 300 gallons is the minimum water tank capacity.
    2.) A CAFS system typically operates with a concentrate induction rate of between one tenth of one percent to seven tenths of one percent.

    Check out a book on Class "A" foam written by Dominic Colletti of Hale Products for an indepth look at all foam system types and operations.

    I hope this helps.

    Hi.

    In My Dept We Run A CAFS With A 300 Gallon Tank And Depending On The Situation Our Precentage Can Range From .1%(Wet Foam) to 1.5%(Dry Foam). We Run A 'Sunffer' Unit From The Snuffer Corp., You Can Contact Them And They May Be Able To Give You Some More Information About CAFS. Have A Good One And Stay Safe!

    And hopefully your Pierce will work, assuming that's what you bought.

    I can not help with the CAFS question, however I do have a question for a few of the others. It was my understanding that NFPA 1901 states that the minimum tank size for a class A pumper is 500 gallons. If it is not, I was wondering when NFPA changed 1901?

    Thumbs up

    Yes it is a Pierce. It is a Lance 2000 series with the biggest 10 man cab offered, top mount, rescue and engine style compartments, top bins, light tower. Should be a nice truck once it's up and running.

    The current NFPA 1901 says 500 gallon water tank on a pumper.
