HYDRA BIG TRIO Scalemaster 1" - 20 Zoll Anti-Limescale Water Filter

HYDRA BIG TRIO Scalemaster 1” - 20 Inch Anti-Scale Water Filter

HIGH-PERFORMANCE BIG TRIPLE filter housing with a one-piece head

A limescale water filter is the ideal solution for effectively protecting your home from limescale. These filters prevent the build-up of limescale and ensure soft, scale-free water, which extends the service life of your appliances and is gentle on your skin and hair.

This works through the self-cleaning/backwash pre-filter with 90 micron, a CPP 20 BIG ScaleArmor™ - 5 mcr Anti-Scale Filter Cartridge and a final water treatment stage with the CB CARBON BLOCK cartridge.

The CB - VOC 20 BIG 5 mcr - activated carbon block is made of compressed activated carbon and filters contaminants from the water such as chlorine, organic contaminants, light hydrocarbons, solvents, pesticides, insecticides, oils and aromas, taste impairment, odour impairment, fine particles (rust, limescale flakes, sand, scales) and suspended solids.

The filter cleans the water to 5 microns.



Use, scope, dimensions:

The 3-stage water treatment system is designed to save a great deal of space and is easy to install.

The HYDRA TRIO house water filter has a drain funnel/backflow protection to safeguard the drinking water supply.

The HYDRA TRIO is used for filtering and treating drinking water,  domestic water and wastewater, and protects fittings, pumps, water tanks and other technical systems as well as the pipework.
