The FP4 (4-position) portable flocculator was developed for optimum use in the field. It runs on 100-240 V mains power supply or using 12 DC by connecting it to a normal battery or a car cigarette lighter. The P4 features a non-slip base that ensures the stability of the beakers during operation.

It is particularly suitable for carrying out Jar Tests for optimizing the dosing of coagulants and polyelectrolyte in the proximity of water treatment plants.
