Industrial performance and superior protection
Rainwater NW 32 is a professional-grade sediment filter designed to mechanically capture suspended solids in water such as sand, silt, rust and mud. Thanks to its special centrifugal (cyclonic) technology, it separates heavy particles in the water by centrifugal force and directs them to the bottom of the filter bowl. This technology reduces the load on the filter cartridge, extending its service life and minimising pressure loss. Built with Made in Belgium engineering, NW 32 offers consistent water quality in industry and facility management thanks to its durable construction.
Centrifugal pre-filtration
Its advanced cyclonic design separates coarse sediment before it reaches the filter element, which means less maintenance and longer filter life.
High, steady flow rate
With an average flow capacity of 6.5 m³/hour, it delivers high-performance filtration without slowing the water flow.
Large filtration surface
The large 840 cm² surface area maximises particle-holding capacity, increasing system stability.
Visual check through the clear bowl
The filter's level of contamination can be monitored at any time through the clear bowl, without stopping the system.

Product description
Sand, mud, rust and sediment carried in mains, well or rainwater wear out plumbing, pumps and downstream purification equipment. NW 32 is a sediment pre-filter fitted at the water inlet that mechanically captures these solid particles.
Who is NW 32 suitable for?
For industry, facilities, production lines and high-volume water applications. With a 1 1/4” connection, it provides an average flow rate of 6.5 m³/hour.
How does it work?
As water passes through the filter element, the 25-micron pores let the water through and retain larger particles; this is a purely physical straining process, not a chemical one. The multi-layer filter structure holds dirt better even under high sediment loads, while the large filtration surface allows high flow with low pressure loss.
A sediment filter does not remove dissolved chemicals such as chlorine or microorganisms on its own; for that reason it is used as a pre-filter ahead of softening, activated carbon, reverse osmosis and UV systems, protecting them.
Technical data
- Connection size: 1 1/4”
- Average flow rate: 6.5 m³/hour
- Filter rating: 25 µm
- Filtration surface: 840 cm²
- Operating pressure: 10 bar (maximum 16 bar)

Frequently asked questions
What does NW 32 do?
It mechanically captures solid particles in the water such as sand, mud, rust and sediment, protecting the plumbing and downstream purification equipment.
Does NW 32 remove chlorine or bacteria?
No. A sediment filter only captures solid particles; chlorine requires activated carbon, and microorganisms require UV or reverse osmosis.
What are its flow rate and connection size?
With a 1 1/4” connection, it provides an average flow rate of 6.5 m³/hour.
When should the filter be replaced?
As the filter fills, the pressure difference between inlet and outlet increases and the flow drops; this indicates that it is time for cleaning or replacement.
How long is the warranty?
It is covered by a 2+8 year warranty.
