The ROYAL filter, together with the Royal multifunctional microfiltration media, is designed for microfiltration of water in hot tubs, swim spas and smaller pools and wherever conventional cartridge filters are used.
The microfiltration media must be purchased with the filter.
It has a cylindrical shape, its bottom part is equipped with a replaceable thread adapter or just a hole depending on the type of filter fitting in the given 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.
