Swn 4sd filter

Swan 4SD Bayonet Filter for Water Prefiltration

The Swan 4SD is a bayonet filter cartridge designed for the mechanical prefiltration of drinking water in water treatment systems.

The Swan 4SD is the Swan-branded equivalent of the Water Pro SD11 and uses a 5 µm melt-blown polypropylene filter cartridge.

Its main function is to retain sediment and particles in the water before they reach downstream filtration stages. It is therefore particularly suitable as a prefilter for microfiltration and reverse osmosis systems, helping protect carbon block filters, membranes and other system components.

5 µm Mechanical Filtration

The Swan 4SD uses melt-blown polypropylene technology designed for the mechanical retention of particles.

The filter retains turbidity, silt, algae and solid particles down to 5 µm, providing an initial barrier against sediment present in the incoming water.

The filtration process is exclusively mechanical. The Swan 4SD is not an activated carbon filter and is therefore not primarily designed to reduce chlorine, odours or tastes.

Prefilter for Microfiltration and Reverse Osmosis

The Swan 4SD is particularly useful as the first filtration stage in systems incorporating additional water treatment technologies.

The preliminary removal of sediment helps protect downstream stages against excessive particle accumulation and premature clogging.

It can be used to protect:

• carbon block filters
• reverse osmosis membranes
• microfiltration systems
• other components sensitive to sediment

Using a prefilter therefore helps reduce the impurity load reaching downstream stages and contributes to maintaining their performance over time.

Flow Rate up to 5 Litres per Minute

Compared with the Swan 2SD, the Swan 4SD provides a higher flow rate of up to 5 litres/min.

This makes it particularly suitable for systems requiring a greater supply of treated water and for applications with higher consumption.

Actual flow rate may vary depending on water pressure, system conditions and the level of contamination accumulated in the cartridge.

Vertical or Horizontal Installation

The Swan 4SD can be installed in either a vertical or horizontal position.

This makes it easier to integrate the cartridge into systems with different layouts and available installation spaces.

No Effect on Taste and Odour

Since the Swan 4SD provides mechanical filtration only, the cartridge is not designed to alter the organoleptic characteristics of the water.

Its function is focused on the physical removal of sediment, suspended particles, turbidity and other solid impurities.

Suitable for Drinking Water

The Swan 4SD is designed for the treatment of already potable water.

The equivalent Water Pro SD11 model is TÜV certified and specified for use with drinking water.

Applications

The Swan 4SD is suitable as a prefilter for:

• microfiltration systems
• reverse osmosis systems
• domestic water treatment systems
• professional water filtration systems
• systems using activated carbon filters
• drinking water production and dispensing systems
• systems requiring high-flow sediment prefiltration

Swan 4SD and Water Pro SD11

The Swan 4SD is the Swan-branded equivalent of the Water Pro SD11.

Both use a 5 µm melt-blown polypropylene cartridge designed for the mechanical prefiltration of drinking water.

The SD11 model provides a 5 litres/min flow rate, higher than the SD03 model, making it particularly suitable for systems requiring greater flow capacity.

The filter's main function is the mechanical removal of sediment and particles, helping protect downstream filtration stages.

Why Choose the Swan 4SD?

The Swan 4SD is designed for applications requiring a first stage of high-flow sediment prefiltration in a water treatment system.

Key benefits include:

• 5 µm mechanical filtration
• melt-blown polypropylene
• removal of turbidity, silt, algae and suspended particles
• protection for downstream filters and membranes
• flow rate up to 5 litres/min
• vertical or horizontal installation
• suitable for drinking water
• TÜV certification
• ideal as a prefilter for microfiltration and reverse osmosis
• suitable for systems requiring higher flow rates

The Swan 4SD therefore provides an effective solution for high-flow mechanical prefiltration, designed to protect downstream water treatment stages from sediment and particles.
