Can I use a standard foam eductor with Class A foam?
Yes you CAN but it will induct a LOT more foam than is needed. Class A foams are typically used at percentages of less than 1%. If a standard eductor is used you will use 3 to 6 times more foam which will not work any better and will cost more. Modifications are currently available from some eductor manufacturerss that allow for a fixed 0.5% setting. As long as all requirements are met for use of the eductor as outlined in the manufacturer’s information, the use of Class A foam can be accomplished. Howver, the the low percentage operations that are possible with the TFT PRO/portioner will not be possible with any type of eductor. More information on this operation is available in the Class A foam workbook.
