PROPRIETARY PRE-FILTRATION TECHNOLOGY

First-Stage Pre-Filtration & Non-Potable Water Reuse

The Pre-Screen filter is installed at the beginning of the rainwater collection system to intercept leaves, debris, and contaminants. By removing these impurities, it ensures collected rainwater is clean and safe for non-potable applications, including landscape irrigation, toilet flushing, and industrial processes requiring high purity.

Designed and manufactured by I Controls Solution, our patented and tested Pre-Screen Filters withstand high hydraulic flowrates while delivering stress-free operation and low periodic maintenance for commercial and industrial facilities.
