Royal filter for Sundance hot tub (880 Series – 6540-488)

This filter replaces both the standard filter cartridge and the disposable Sundance Filter (SC721 and SC722).

It has a cylindrical shape, its lower part is equipped with a replaceable thread adapter or just a hole depending on the type of filter fitting in the hot tub. The bottom third of the ROYAL FILTER length is solid solid wall all the way around, the top two thirds are perforated and the top lid of the ROYAL FILTER is also perforated. From the lower inlet opening up to two-thirds of the length of the ROYAL FILTER, there is a central perforated inlet nozzle which has a solid solid wall at its mouth, which defines the space for the ROYAL FILTER’s skimmer. At this level, a skimmer grid is located around the entire perimeter to separate the skimming area from the ROYAL multi-functional microfiltration media.

Filtration method via ROYAL FILTER:

Thanks to the perforated design of the body and the perforated central suction nozzle of the ROYAL FILTER, the water is drawn in all directions by the whirlpool pump through the Royal multifunctional microfiltration medium, which ensures thorough microfiltration from 3 microns.

Due to their robustness, the service life is estimated to be many years, only the multi-functional microfiltration medium is changed and this approximately once every 12 months.

Benefits of ROYAL FILTER:

• It is versatile and significantly saves the environment and especially your money!
• It provides thorough microfiltration of water from all particles from 3 microns in size, which is at least 10 times better than filtration through conventional cartridge filters or sand filtration. Safely filters out oils, grease, deodorants, antiperspirants, biological material, urea, and all particles invisible to the naked eye.
• Provides significant savings in money, water and cleaning time over conventional cartridge filters. Savings are a minimum of forty litres of water and 25 minutes of time per week cleaning of two conventional cartridge filters, and almost 100% savings in chemicals used to clean conventional cartridge filters.
• The Royal multi-functional filter media simply needs to be washed once a week in a washing machine without washing powder and fabric softener, in a quick programme of about 15 minutes at a temperature of about 35 degrees and left to dry freely.
• If you have iron or manganese in your water, the ROYAL FILTER will safely and effectively filter it out of your hot tub water without the addition of various chemicals.
• In combination with KYROL TC – a unique chlorine-free disinfectant and other chlorine-free hot tub water treatment components, it ensures clean and healthy water in your hot tub or swim spa.
• It guarantees a high water flow rate compared to commonly used conventional cartridge filters, thus significantly saving strain on the pumps and allowing you to make the most of their hydrotherapeutic performance. This is not always possible with conventional cartridge filters due to their poorer throughput caused by scale and sludge, which is also often the cause of pump failures.
• Thanks to the integrated skimmer at the bottom of the filter, it traps sediment and larger impurities that do not get back into the water in the whirlpool when the Royal multifunctional microfiltration medium is replaced, as is common with conventional cartridge filters. This guarantees minimal or cartridge filters, these will leave a great deal of debris that will simply wash out of the water when the filter is removed.
• The two components of the ROYAL FILTER – the ROYAL FILTER body and the ROYAL multi-functional microfiltration media are two separate parts and are fully recyclable.
• Cartridge filters have a maximum lifespan of one year, recycling cartridge filters can be a problem as two different materials are fixed together – plastic and filter cloth.
