The critical first barrier for sensitive systems
Rainwater NW 280 is manufactured with Made in Belgium engineering to physically capture sand, silt, rust, mud and suspended solids carried in water, so that the rest of the system runs more stably and lasts longer. Its special centrifugal (cyclonic) technology separates coarse particles by centrifugal force, directs them to the bottom of the bowl and prevents premature clogging of the filter. With a high flow capacity of 7 m³ per hour, it delivers uninterrupted pre-treatment performance in commercial and industrial processes.
A critical front-line barrier
It is the most reliable line of defence, preventing softening, R/O, UV and process equipment from being damaged by particles and clogging prematurely.
High-flow, uninterrupted performance
With an average flow capacity of 7 m³/hour, it provides powerful, stable filtration without reducing water pressure in your plumbing.
Centrifugal pre-filtration
Its advanced cyclonic design separates heavy sediment before it reaches the filter element, minimising operating and maintenance costs.
Optimum filtration surface
The extended 530 cm² surface area maximises dirt-holding capacity and lengthens filter replacement intervals.

Product description
Sand, silt, rust and sediment carried in mains, well or rain water wear out plumbing, pumps and downstream purification units. The NW 280 is a sediment pre-filter fitted at the water inlet that mechanically captures these solid particles.
Who is the NW 280 suitable for?
For building inlets, hotels, restaurants and industrial lines. With a 1” connection size, it provides an average flow rate of 7 m³/hour.
How does it work?
As water passes through the filter element, the 25-micron pores let the water through and hold back larger particles; this is a purely physical, not chemical, filtration. The multi-layer filter structure retains dirt better even under high sediment loads, and the large filtration surface provides high flow and low pressure loss.
A sediment filter does not on its own remove dissolved chemicals such as chlorine, or microorganisms; for this 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 the NW 280 do?
It mechanically captures solid particles in the water such as sand, silt, rust and sediment, protecting the plumbing and downstream purification units.
Does the NW 280 remove chlorine or bacteria?
No. A sediment filter only captures solid particles; activated carbon is needed for chlorine, and UV or reverse osmosis for microorganisms.
What are its flow rate and connection size?
With a 1” connection size, it provides an average flow rate of 7 m³/hour.
When should the filter be replaced?
As the filter fills up, the pressure difference between inlet and outlet increases and the flow drops; this indicates that it is time to clean or replace it.
How long is the warranty?
It is covered by a 2+8 year warranty.
