Roth downpipe filter

Downpipe filter for rainwater harvesting

This downpipe filter is designed for efficient rainwater harvesting from downpipes. It filters coarse and fine particles such as leaves or insects from the rainwater runoff and directs the purified water into a cistern, barrel, or above-ground storage tank. This makes the filter ideal for home gardens, carports, or commercial rainwater harvesting.

Available in two material variants—plastic or metal—the filter is weather-resistant and durable. Plastic models are available in brown or gray, metal variants in copper or titanium zinc. The integrated filter unit with a mesh size of 0.315 mm ensures a good balance between filtration and flow rate.
