W'eau HDPE-450 top-mount sand filter 8m³

The W’eau HDPE-450 Top Mount sand filter 8 m³/h is a powerful and durable sand filter for efficiently filtering swimming pool water. With a 450 mm filter tank and a maximum flow rate of 8 m³ per hour, this sand filter offers sufficient capacity for medium-sized private swimming pools. The larger filter surface area ensures that pool water is effectively guided through the filter medium, removing dirt particles from the water.

The filter tank is manufactured from strong HDPE (High Density Polyethylene). This material is excellently suited for pool installations: it is sturdy, moisture-resistant, and cannot rust. In combination with the top-mounted 6-way valve, you get a compact and user-friendly filter solution that can be easily integrated into an existing or new pool installation.

Powerful filtration of 8 m³ per hour

With a maximum flow rate of 8 m³/h, the W’eau HDPE-450 can theoretically process approximately 8,000 liters of pool water per hour.

During the filtration process, the pool pump draws water from the swimming pool. The water is then pumped to the filter tank and guided through the filter medium. Dirt particles are trapped within the filter material, after which the filtered water flows back to the pool via the return line.

As a result, small impurities are continuously removed from the pool water. In combination with a proper water balance and correct disinfection, this contributes to clear and clean pool water.

450 mm filter tank for a larger filter surface area

The HDPE-450 features a filter tank with a diameter of 450 mm. Consequently, this version offers a larger filter surface area than, for example, the HDPE-350 and HDPE-400.

A larger filter tank means that more filter medium can be used. This allows more dirt to be trapped before the filter medium needs to be cleaned.

The HDPE-450 is therefore an attractive mid-size option for pool owners who want more filtration capacity without immediately choosing a very large sand filter.

Compact Top Mount design

The W’eau HDPE-450 is designed as a Top Mount sand filter. This means that the 6-way valve is placed directly on top of the filter tank.

An important advantage of this design is that the complete sand filter requires relatively little floor space. In a Side Mount version, the valve is located next to the filter tank, making the installation wider.

This makes the HDPE-450 easy to place in, for example, a technical room, shed, equipment box, or next to the pool.

When placing it, ensure there is sufficient free space above the sand filter for operating and maintaining the 6-way valve.

Multifunctional 6-way valve

With the integrated 6-way valve, you can easily control the various functions of the sand filter. This means you do not need to disconnect pipes for normal maintenance.

The different settings are:

Filter – the normal operating position where pool water flows through the filter medium.

Backwash – reverses the water flow through the filter bed so that accumulated dirt is flushed out via the drain.

Rinse – used after backwashing to properly re-settle the filter medium and discharge any remaining dirt.

Waste – discharges pool water directly to the drain without passing it through the filter medium.

Circulate – circulates the water through the system without filtration.

Closed – closes off the water flow through the valve.

Note: always switch off the pool pump completely before changing the setting of the 6-way valve.

Simple cleaning by backwashing

An important advantage of a sand filter is its simple maintenance. As the pool is used, more and more dirt collects in the filter medium. This increases resistance and can eventually reduce the flow rate.

Instead of opening the filter tank and cleaning the filter material manually, you simply use the Backwash function.

This temporarily reverses the water flow. The accumulated dirt is loosened from the filter bed and discharged via the waste water connection.

Afterward, you run the sand filter on Rinse for a short time and then return the 6-way valve to Filter.

Suitable for filter sand and filter glass

The W’eau HDPE-450 can be filled with various suitable filter media. The most commonly used options are filter sand and filter glass.

Filter sand is the traditional solution and is known for its simple operation and attractive price.

Filter glass is a popular alternative to sand. Depending on the filter glass used, it can offer fine filtration and generally has a long service life.

Always use the prescribed quantity and grain size for the HDPE-450. Too little, too much, or the wrong grain size can affect the filtration and flow rate.

Strong HDPE filter tank

The filter tank is manufactured from HDPE, or high-density polyethylene. This plastic combines a relatively low weight with a sturdy construction.

An important advantage is that HDPE cannot rust. This makes the material highly suitable for pool installations, where components are exposed to moisture and pool water for long periods.

The sturdy construction ensures the sand filter is suitable for years of seasonal use, provided the installation is correctly placed, maintained, and properly protected during the winter period.

Ideal for medium-sized pools

Thanks to its capacity of 8 m³/h, the HDPE-450 is primarily attractive for medium-sized private swimming pools.

Think, for example, of larger frame pools, steel-wall pools, wooden pools, and smaller to medium-sized permanent pools.

When choosing a sand filter, you should not only look at the maximum pool volume. Pipe length, pipe diameter, height differences, bends, heat pumps, and other accessories also cause resistance and can reduce the actual water flow rate.

Therefore, it is important to match the sand filter and pool pump as a single unit.

Combinable with a swimming pool heat pump

Do you want to use a pool heat pump in addition to filtration? Then the HDPE-450 can become part of a complete pool installation.

The normal sequence is, for example:

Swimming pool → pool pump → sand filter → bypass/heat pump → return to pool.

The sand filter is positioned before the heat pump so that the water is filtered first before flowing through the heat pump’s heat exchanger.

With a bypass, you can then set how much water is routed through the heat pump.

Powerful and reliable filtration for your pool

The W’eau HDPE-450 Top Mount sand filter 8 m³/h is an excellent choice when you are looking for a sturdy sand filter with sufficient capacity for a medium-sized pool. The 450 mm HDPE filter tank offers a spacious filter surface area, while the maximum flow rate of 8,000 liters per hour ensures powerful water circulation.

The combination of the durable HDPE filter tank, the compact Top Mount construction, and the multifunctional 6-way valve also makes the HDPE-450 easy to use and maintain. Thanks to the ability to use filter sand or filter glass, you can configure the installation according to your own preference.

A powerful, compact, and low-maintenance sand filter for those who want to enjoy clean and clear pool water throughout the entire swimming season.
