Description
This simple but powerful sand filter set is perfectly suited for medium-sized above-ground and built-in pools. We recommend this filter set for above-ground pools with a maximum capacity of 24,000 litres. The filter set is equipped with a polyethylene sand filter in combination with a simple self-priming pool pump. The 6-way tap allows you to easily operate the different settings of the filter.
Medium duty application
This filter set is equipped with a swimming pool pump with a maximum pump capacity of 8,500 litres per hour. This makes the filter set ideal for medium-sized above-ground and built-in swimming pools. The filter set is suitable for swimming pools with a medium-heavy application. This means that the pump has sufficient capacity to bridge distances of 5 to 10 metres to the swimming pool and a vacuum cleaner can be connected to the pump without any problems.
Complete filter set (excluding filter medium)
This DK 400 filter set is complete with all accessories, so you can install the sand filter set immediately. The filter set is supplied with sand filter tank, pool pump, 6-way tap, 32 and 38 mm connection and a plug with earth leakage circuit. To use the filter set, you only need the correct amount of filter medium.
6 way tap
The DK 400 filter set is equipped with a handy 6-way tap. This allows you to easily operate the different settings on the filter. Below we list the settings for you and briefly explain their use.
- Filtering; water flows from top to bottom in the filter tank (used 99% of the time)
- Backwashing; water flows from bottom to top in the filter vessel to rinse the filter material (use this setting when you notice reduced filtration/flow)
- Rinse; flush away dirty water after backwashing
- Close; you close all entrances and exits
- Waste; drain pool water directly to the sewer (when you want to lower the water level)
- Circulate; allow water to flow around only, without passing through the filter (almost essential when treating with chlorine shock, for example with green pool water)
Filter medium; sand, glass or Aqualoon
The filter tank of the DK 400 is filled with filter sand, filter glass or Aqualoon. This is not included as standard. Filter sand is traditionally used the most, is the cheapest and must be replaced after about 5 years. Filter glass is somewhat more effective, slightly more expensive, but less of it is needed and you only have to replace it after 10 to 15 years. The 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: 25 kg
- Required amount of filter glass: 22 kg
- Required amount of aqualoon: 700 grams
