The K40 AQUAKLEAR is designed to improve the water quality of pools, hot tubs, spas, water features, and other related applications. Reducing bacterial levels and improving filtration in pools etc. leads to clearer and more pleasant water and a reduction in maintenance regimes and associated costs and a reduction in backwash. The K40 AQUAKLEAR has a range of benefits designed to make your system cheaper and easier to maintain, and more pleasant to use. The K40 AQUAKLEAR is designed to reduce bacteria levels, to reduce hazardous chlorine use (and its unpleasant smell), and to help improve filtration for lower turbidity and reduced backwash. The unit can be fitted around pipes of up to 63mm diameter and of any material with no plumbing required.
