NW25 Cintropur mechanical sock filter

Pre-filter for effective installation protection

The Cintropur NW25 is a modern pre-filter designed to reduce mechanical impurities present in water. It performs excellently wherever the goal is to capture solid particles before the next treatment stage or before supplying the entire building installation.

The polypropylene cartridge used in this model effectively reduces the presence of contaminants such as:

• sand,
• silt,
• rust,
• other suspended solids and sediment.

As a result, the filter helps keep the installation in better condition, reduces the risk of sediment buildup, and provides practical protection for subsequent devices operating in the system. It is a very good choice as a water filter for a single-family home, as well as a preliminary stage before more advanced solutions such as an osmotic filter, a reverse osmosis filter, a reverse osmosis system, or reverse osmosis.

How does the Cintropur NW25 work?

The filter uses a cyclonic effect, which distinguishes the Cintropur design from many standard mechanical filters. Water is set into a swirling motion by the centrifuge installed as standard. This operating method allows larger particles to be initially separated even before the final filtration stage.

The centrifugal force imparted to the liquid stream causes larger contaminants to settle at the bottom of the bowl. Then the filter sleeve is responsible for final filtration according to the applied filtration fineness. This combination of two operating mechanisms improves the filter’s effectiveness and helps maintain high flow performance.

Key design advantages

• water purification using the cyclonic effect,
• centrifuge installed as standard,
• effective reduction of mechanical impurities,
• high capacity suitable for supplying the entire house,
• low pressure drop during filtration,
• low operating cost,
• durable, refined design,
• easier servicing thanks to the air vent and drain plug.

Why does this model work well in the home?

The filter has been designed for high capacities, so it can effectively purify water for the entire house without noticeably reducing user comfort. The pressure drop during filtration is low, which is especially important in installations where stable flow matters.

Cintropur is valued for its durable construction and economical operation. It is a solution for users who expect effective installation protection while also wanting to keep operating costs at a reasonable level.

Filter cartridge and filtration fineness

The set includes a factory polypropylene cartridge with a filtration fineness of 25 microns. This grade works well as preliminary mechanical filtration when the goal is to capture typical solid contaminants present in utility water.

The model is also compatible with filter meshes of other fineness levels, allowing the filtration method to be matched to the installation’s operating conditions.

• 5 microns,
• 25 microns,
• 50 microns,
• 100 microns.

Set contents

The комплект includes all the basic elements needed for filter installation and operation:

• Airwatec Cintropur NW25 filter,
• two half-unions with O-ring sealing, enabling connection to a 3/4-inch installation, while other diameters can be obtained using reducers,
• wrench for unscrewing the transparent housing,
• factory 25-micron cartridge.

Operation and servicing

Filter operation has been designed so that everyday use is convenient and does not require complicated procedures. The transparent housing makes it easy to check the level of contamination, and the included wrench allows the housing to be quickly unscrewed during service work.

In practice, operation primarily includes:

• periodic removal of larger contaminants through the drain plug,
• checking the contamination level of the filter element,
• replacing the cartridge when necessary,
• venting the filter after servicing.
