Cal Spas Dually Spa Pump for Hot Tubs is The Most Powerful Water Flow System in the Industry. With more than 10 years in development, the next generation in water flow systems is here. The revolutionary Dually Pump in Cal Spas' line of eco-friendly hybrid spas is designed to manage the water flow demands of a 36-jet spa system with only one pump. One dually pump is equivalent to a spa with a two pump water management system and produces enough thrust to properly maintain a water flow of 280 gallons per minute on high speed. The dually pump system also efficiently circulates freshly filtered and heated water throughout the entire spa during filtration cycles and normal operation, all while using 50% less energy when compared to a two pump system. Additionally, by reducing the number of pumps in a spa, the entire spa experience is naturally much quieter allowing for a more relaxed environment. Cal Spas line of hybrid spas are also eco-friendly and offer several design features that conserve energy and reduce chemical consumption. Our Eco-friendly Bio-Clean™ Antimicrobial Filter utilizes a special bacteria-fighting agent that is molded into the fabric of the filter called Microban. This unique protectant prevents harmful microbes and bacteria from reproducing. Microorganisms such as bacteria, mold and mildew can cause stains, odors and product deterioration resulting in an addition of extra chemicals treatments for cleaning and water purification. With Microban antimicrobial protection, microbial reproduction is inhibited throughout the product's useful lifetime and minimizes the need of chemical usage during regular cleaning and maintenance. Microban antimicrobial protection ensures continuous, durable and effective antimicrobial protection that provides an added level of defense against damaging microbes without ever wearing off or washing away. Additionally, a Bio-Clean™ Antimicrobial Filter is easy to clean and lasts longer than regular spa filters (up to 18 months), eliminating the need to replace an ordinary filter every 3 months. To further reduce the need for extra sanitizers to treat spa water, our Pure Cure UV Sanitizing System purifies water by using the power of ultraviolet light to kill bacteria, algae and viruses. Feel, see, and smell the difference in water clarity with the most efficient and powerful water flow system in the hot tub industry.
