HYDRA BIG TRIO Rainmaster 1” - 20 Zoll Household Water Filter Well Water Filter

HYDRA BIG TRIO Rainmaster 1” - 20 inch house water filter

HIGH-PERFORMANCE BIG triple-filter housing with one-piece head

This filter system treats water at high capacity at low cost and filters out pollutants as well as fine particles from the water.

This works through the Self-Cleaning/Backwash pre-filter with 90 micron, an FA pre-filter with 25 micron, and a final water treatment stage with the CB CARBON cartridge.

The CTO 20 BIG 10 mcr - activated carbon block is made of compressed activated carbon and filters pollutants from the water such as chlorine, organic pollutants, light hydrocarbons, solvents, pesticides, insecticides, oils and aromas, taste impairments, odor impairments, fine particles (rust, limescale flakes, sand, flakes) and suspended matter.

The filter purifies the water to 10 microns.



Use, scope, dimensions:

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

The HYDRA TRIO house water filter is used for filtration and treatment of drinking water,  house water and waste water; it serves to protect fixtures, pumps, water tanks and other technical systems as well as the pipework.
