Originally at the Yatesbury airfield before being moved to Filton airfield. It carried 8 Karbono 60lb liquid Co2 cylinders, 200 gallons of water, Xhaust-suds foam liquid giving 1,000 gallons of foam using the onboard water.

Ed: thanks Bob I knew you would have the info. By the way it is "Xaust" here is the reference

Thanks for the correction Ed, and I was doing so well. Does anyone know if this appliance is still about? I have not seen any reference to it for a long time. The appliance is visible in film of the first Brabazon take off and landing.

Five X expansion seems like a very wet foam for an airfield tender. Or, was the foaming agent supply designed to work with an additional supplementary water supply on top of the 200 gallons in the on board tank?

The pump was 200 gallons a minute, 1 gallon of xaust would give 1,000 gallons of foam, an external water supply could be also connected. I don't know the quantity of xaust available but, xaust was sold in 2 gallon cans so maybe that was how much was carried
