Out Standing Filtering
*A next generation alternation to the traditional sand filters - the Waterdance filter combines many practical functions into one machine.
*It has two filtering levels: At first, the fine screen filters normal impurities, afterward the high precision (5μm) filter bag filters even smaller particles as well as the un-reacted chemical in the process of automatic chemical dosing, ensuring the water quality and the health of swimmers.
*We are continuously developing our products with high precision and high efficiency period, making sure of the recycling use of pool water with minimum consumption of water resources. |
