Sand filter set DK 310 - 4 m³/h

The DK 310 - 4 m³/h sand filter set is an ideal choice for filtering above-ground pools. We recommend this sand filter set for pools with up to 16,000 litres of water. In addition, this set is suitable for low-resistance setups. This means that the distance between the pump and the pool should not exceed 3 metres. Intensive vacuuming is also not possible. The design flow rate of the DK 310 - 4 m³/h is 4 m³ per hour. The design flow rate indicates the maximum amount of water the set pumps per hour. This top-mount sand filter set is equipped with a 6-way valve with all functions. We explain these functions for you below. In short, the DK 310 - 4 m³/h helps you on your way to a beautiful pool. Let the summer come!

Light application

This filter set is equipped with a pool pump with a maximum pump capacity of 7,000 litres per hour. This makes the filter set ideal for smaller above-ground and built-in pools with little resistance from other equipment or long piping. Please keep in mind that due to its light application, the pool pump is not powerful enough to cover long distances or for intensive pool vacuuming.

Complete filter set (excluding filter medium)

This DK 310 filter set comes complete with all accessories, allowing you to connect the sand filter set directly to your pool. The filter set is supplied with a sand filter tank, pool pump, 6-way valve, 32 and 38 mm connections, and a plug with an RCD (residual current device). To start using the filter set, you only need the correct amount of filter medium.

6-way valve

The DK 310 filter set is equipped with a convenient 6-way valve. This allows you to easily control the different settings. Below, we list the settings for you and briefly explain their use.

• Filter; water flows from top to bottom in the filter tank (used 99% of the time)
• Backwash; water flows from bottom to top in the filter tank to rinse the filter material clean (use this setting when you notice reduced filtering/flow)
• Rinse; to flush out dirty water after backwashing
• Close; closes all inlets and outlets
• Waste; drains pool water directly to the sewer (when you want to lower the water level)
• Circulate; circulates the water only, without passing it through the filter (essential when treating with chlorine shock, for example, in case of green pool water)

Filter medium; sand, glass, or Aqualoon

You fill the filter tank of the DK 310 with filter sand, filter glass, or Aqualoon. This is not included as standard. Filter sand is traditionally the most commonly used, is the cheapest, and must be replaced after about 5 years. Filter glass is somewhat more effective and slightly more expensive, but you need less of it and only have to replace it after 10 to 15 years. Aqualoon filter balls are the lightest filter medium and can be washed after use. The balls must be cleaned at least once per season.

• Required amount of filter sand: 16 kg
• Required amount of filter glass: 13.6 kg
• Required amount of Aqualoon: 450 grams
