A high-capacity industrial protective shield
Rainwater NW 650 is manufactured to Made in Belgium standards to protect large systems by mechanically removing sand, silt, rust and suspended solids from the water. With its huge 1288 cm² filtration surface, it eliminates the clogging and pressure loss problems that small filter housings can cause in high-flow applications. Thanks to its special centrifugal (cyclonic) filtration technology, coarse particles are separated by centrifugal force, maximising the life of the filter element. With a capacity of 25 m³ of water per hour, it delivers uninterrupted performance for large factories, agricultural irrigation projects and rainwater/well water recovery facilities.
Huge water flow capacity
With an average flow rate of 25 m³/hour, it ensures uninterrupted water flow without pressure loss on large-scale industrial lines and building inlets.
Massive filtration surface
The 1288 cm² filter area maximises dirt-holding capacity, significantly extending maintenance intervals even with very heavy sediment loads.
Centrifugal pre-filtration
Its advanced cyclonic design separates large sediment by centrifugal force before it reaches the filter, reducing the load on the filter cartridge and increasing system efficiency.
Visual check through the clear bowl
On busy production lines, the filter's level of contamination can be monitored at any time through the clear housing, 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 650 is a sediment pre-filter fitted at the water inlet that mechanically captures these solid particles.
Who is NW 650 suitable for?
For large factories, building inlets, well/rainwater and agricultural irrigation. With a 2 1/2” connection, it provides an average flow rate of 25 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.

Frequently asked questions
What does NW 650 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 650 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 2 1/2” connection, it provides an average flow rate of 25 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.
