Upgrade your sand filter to the Forty-X™ disc filter

Increase filtration capacity and performance in existing footprint

The Forty-X™​ Disc Filter is a high-rate tertiary filter that requires a fraction of the footprint required by traditional sand filters. It is ideal for upgrading traveling bridge and deep-bed sand filters.

The Forty-X Disc Filter is designed with unique pleated, woven media filter panels. It uses an inside-out flow pattern that reduces backwash cycles and energy demand leading to lower lifecycle costs.
