Notes on the admixing rate
The specified admixing rates are applicable for synclic foam agents or foam
concentrates. The scale on the setting sleeve is calibrated for synthetic
multi-grade foam agents.
Especially with structural viscous foam agents (e.g. vaPUREx
F-5 #8342), it may be necessary to adapt the suction side when using a
38 mm suction hose at low operating temperatures between 0°C and -5°C
in order to achieve a real proportioning rate of 3%, .
The aspirated volume, especially in the range of 0.1 to 0.5 %, depends
strongly on the viscosity of the foam agent. In view of this, the EN 16712-1
standard allows, for up to 1%, a large rate tolerance of 50%.
Water is for example significantly more aspirated.
The scale on the setting sleeve thus only indicates a guide value.
Note In position "0", a minimum residual quantity can be aspirated.
