Filter Kit C

Designed for large roof areas up to 800m², this kit features a high-performance two-stage filter, siphon overflow, and calmed inlet. Rainwater initially passes through a cascade filter to remove coarse debris. Subsequently, a fine mesh (0.65mm) sieve captures remaining impurities.

Clean water is gently introduced into the tank via a calmed inlet, preventing sediment disturbance and promoting water quality. This method also oxygenates the water, inhibiting the growth of harmful bacteria. The included siphon overflow with skimming inlet removes surface contaminants, ensuring cleaner stored water.

Key benefits:

Handles extensive roof areas

Advanced two-stage filtration

Protects water quality through calm inlet and oxygenation

Removes surface impurities

How it Works

Water is evenly dispersed across the filter's cascading layers. Larger debris is captured and directed straight to the sewer in the initial filtration stages. The pre-filtered water then passes through a fine mesh (0.65mm) secondary filter, where remaining impurities are washed away into the sewer. Clean water is subsequently channeled into the tank.
