3
/hour (530-
6600 gal/hour).
The water pressure is between 1 and 8 bar (14-120 PSI).
Head loss for MixRite TF 25: Minimum flow 0.1 Bar – Maximum flow 1.5 Bar
The water & air temperature are not less than 4ºC (40ºF) and not more than 40ºC (104ºF)
The flow rate of the additive can be adjusted relative to the flow rate of the water in the range of
0.1% to 1% for Model 001 and of 0.3% to 2.5% for Model 002 and in the range of 1% to 5.5% for
