• Rainus in three colours: Black, Grey and Brown
    Rainus in three colours: Black, Grey and Brown


The 3P Rainus filters debris from rainwater, allowing the clean water to continue through the downpipe. Ideal for retro-fitting to systems which have not yet had a filter fitted, the Rainus is also an excellent soluton to use with soakaways, ponds and infiltration systems.

It is a professional grade filter. It is sufficient to protect the stored rainwater quality even in an underground rainwater tank.

With simple above ground installation, the 3P Rainus is easy to access and maintain. Its removable stainless steel filter separates out debris to below 1mm in particle size keeping flies and mosquitoes out of the rainwater tank.

The Standard Rainus fits downpipes of 80, 90, or 100 mm diameter (usually found in either aluminium or zinc).

The Rainus with UK Adapters is also compatible with 68 mm round UK downpipes and 65 mm square downpipes.
