Description

The filter has two or three side inlets and one or two skimmers, depending on their filtering ability. The two or three side inlets are directed the first towards the side bottom, the second higher and the third even higher. The filter is always placed at the short deep end of the swimming pool and opposite of the wind. The constant flow of the inlets spins the water, and any dirt found in the water at the bottom or the corners rises to the surface and is absorbed by the skimmers. In this way, the bottom and the surface of the swimming pool are always clean, and there are no blind-spots which are not filtered. The filtering ability of the cartridges is 20micron when the filtering ability of the sand filters is 50micron.

 

 

ADVANTAGES OF A CONCRETE SWIMMING POOL WITH COMPACT FILTERING SYSTEM

  • Crystal water
  • Soundless function
  • Easy and simple access
  • Economic – very high pump output (m³/h) with a low energy consumption
  • Much better water recirculation (stirs the whole volume of the water) and water filtering
  • Because of the spin there are no blind-spots
  • Less chemical consumption
  • Easier to clean. There is no need for a flocculant, which is necessary when the swimming pool is filtered with sand filters. There is also no need for high water consumption to do the ‘back wash’ (sand filters’ washing)
  • Low cost of maintaining the pumps
  • A great cost of pump room construction is saved

 

All the materials are European E.C., of high-quality and endurance and meet the strict American and European standards

THE FILTERING SYSTEM INCLUDES:
