HYDRA BIG TRIO Rainmaster 1" LA - 20 inch Rainwater Filter

HYDRA BIG TRIO Rainmaster LA 1” - 20 inch rainwater filter

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

This filter system treats water at high capacity cost-effectively and filters contaminants as well as fine particles out of the water.

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

The LA 20 BIG SX TS - activated carbon granulate water filter 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 impairments, odor impairments.

The filter cleans the water to 25 micron.
