Features: The scale inhibition filter element is made of food grade MSAP scale inhibition and slow release material, with scale inhibition rate of 99% and convenient installation. Molecular scale inhibition technology is adopted, which can reach 0.23PPM in 0.3 seconds in water and reach saturation concentration in 48hours. The slow release-time is long, and the filtering effect is lasting. Insert the scale inhibition inner core into the PP-cotton for use. Easy to install. It is applicable to standards filter element with inner diameter of 28cm/11.02 inch. It can effectively prevent and mitigates the formation of calcium magnesium compounds, and effectively prevent pipeline corrosion, intergranular corrosion, corrosion under scale, etc. It can be connect in multiple sections. Each section is about 5g of reagent, which can handle about 10~15 tons of water. Specifications: Material: PP-material Size: Approx. 32x86mm/12.60x33.86inch Applicable water pressure: 0.4Mpa Applicable water quality: tap water Weight of scale inhibitor: 5g Water treatments capacity: about 20 tons Inner diameter 28cm/11.02inch filter element is applicable Note: Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order.
