The FR-306 Plus is an advanced brushing reservoir developed by Pyxis Lab Inc. to optimize the oxidizer measurement of the ST-765 Sensor. Engineered for durability and efficiency, the FR-306 Plus integrates a high-capacity reservoir with a magnetically coupled brushing mechanism. This design ensures thorough cleaning while minimizing system downtime. The unit supports automated operation modes, making it highly adaptable to a range of industrial and commercial water treatment applications. With its robust construction and enhanced performance features, the FR-306 Plus represents a new standard in brushing reservoir technology.

The front loading end of the reservoir is now made of Polycarbonate for a visual of the brush and offers an easier method of disassembly.
