Public Hot Tubs Have Pressurized Filtration. Shouldn’t Yours?

The hot tub at your public pool, gym, hotel or recreation center is required to have a pressurized filtration system, but your hot tub won’t have one – unless you have a Coast Spa. Coast Spas is one of the only hot tub companies in the world to offer Pressurized Filtration on all their premium hot tubs. Our system, the Hydro Cyclonic Filtration System, is not only commercial-grade and pressurized, but also forces debris to evenly distribute over the filter cartridge in a cyclonic motion. This is a result of Water Diversion Blades directing water into an even, rotating flow around the outside canister wall before being drawn into the filtration media.

83% More Efficient. 20% Faster.

Coast spas teamed up with Pleatco the leader in filtration to test the effectiveness of the Coast spas filtration system. In independent testing from a New York Laboratory they introduced 5 pounds of silica dust into the hot tub water it was found that that Coast Spas’ Hydro Cyclonic Filtration System was 83% more efficient and 20% faster at clearing this silica from the spa water then the leading competitor. Having the filtration process work faster and more efficient means less strain on your pumps and equipment and less power consumption. Over time this equates to significant financial savings, a smaller environmental footprint and equipment that has superior performance over a longer duration.

Built Powerful for Jetted Hydrotherapy. Intelligently Engineered for Energy Savings.

Coast Spas’ Xtreme Line of Jet Pumps provides the power required to get a truly effective massage. From the Monster Flow 7HP pump to the 1.5HP Smart Flow pump, all are designed to push the maximum allowable pressure through to our specially designed Luxury Trillium Massage Jets. During your spa’s filtration cycle, your jet pumps are activated to pull and push water through your hot tub filter.
During the filtration cycle, our Xtreme pumps will run on an ultra low voltage (1.2Amps for 5HP Super Flow Pumps) and at one third the RPM (3450 high / 1150 low). Programmable filtration cycles allow you to control when, and for how long, your jet pumps activate to purge your hot tub of debris. During the programmed filtration time, your hot tub pumps will consume about as much power as your backyard


Self-Cleaning Sweeper Jet

The Floor of a Hot Tub Collects Settled Debris and Contaminants. So Coast Spas Developed the Self-Cleaning Sweeper Jet. It is inevitable that dirt, sand and other debris will find it’s way into your hot tub. It can be brought in on your feet, blow in by the wind or simply fall from the trees or a structure above. Regardless of how it got into your hot tub, the last thing you want is for it to stay in your water – collecting over time on the floor of your spa.

Our Self-Cleaning Sweeper Jet is activated during the filtration cycle and blasts the collected dirt, sand and other debris off the floor to where it can be drawn into the filtration system. It’s incredible how something so small could make such a difference to your hot tub enjoyment.

The Strongest Shells

Coast Spas® has partnered with Owens Corning® to Deliver the Toughest and Most Durable Hot Tub Shells Available. Your hot tub starts its life as a sheet of premium acrylic. It is then heated and vacuum-formed to take on the shape of a hot tub, at this point the acrylic is fragile and flexible.

The acrylic shell is then moved to be reinforced using high-grade Owens Corning® fiberglass. A team of specialists start by applying several layers of fiberglass to the shell, then use rollers to compress those layers together. Steel angle iron is then placed onto those first compressed layers for additional support in specific structural areas.

Additional layers of Owens Corning® fiberglass are then added (up to 12 layers or more are typical for an average-size Coast Spas Model) and compressed again, by hand, to complete the shell.reinforcement.
