Polyphosphate Cristal Metering Devices

The range of crystal metering devices is enriched with a new version of extremely pure spherical polyphosphate/silicate elements.The particular spherical shape permits greated regularity in the consumption of the product and consequently better metering. The presence of silicate also ensures greated protection of the metal parts against corrosion from water.
The range of Opur metering devices goes up to 1 -1/4" and the version with sphrical polyphosphate/silicate elements is also available in these models.
For both models, the spare part is a practical trasparent cartridge
