HYDRA BIG 10 TRIO Rainmaster LA 1” - rainwater filter

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

Innovative backwash system with spring-loaded filter cartridge. When the flush valve is opened, the pressure drop pulls the cartridge downward, cleaning it from the inside as well. A minimum pressure of 1.8 bar is required to ensure backwashing.

Includes hose connector and drain funnel with backflow prevention according to UNI EN 1717-11/2002

Innovative backwash system with spring-loaded filter cartridge. When the flush valve is opened, the pressure drop pulls the cartridge downward, cleaning it from the inside as well. A minimum pressure of 1.8 bar is required to ensure backwashing.

This filtration system treats water highly effectively at low cost and filters pollutants as well as fine particles out of the water.

This is achieved through the self-cleaning/backwash pre-filter with 90 microns, an FA pre-filter with 25 microns, and final water treatment by the LA CARBON cartridge.

The LA 10 BIG SX TS - activated carbon granulate water filter is made of compressed activated carbon and filters pollutants from the water such as chlorine, organic pollutants, light hydrocarbons, solvents, pesticides, insecticides, oils and flavors, and taste impairments, odor impairments.


The filter cleans the water to 25 microns.



Use, scope, dimensions:

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