Features of the Freestyle F-1437 Swim Spa

Vacuum Break Intake System
This safety break feature automatically reduces pump suction in the event of an obstruction or intake blockage.
Bio-Clean™ with TeleWeir Gate
A special bacteria-fighting agent is molded into the fabric of the filter. This prevents harmful microbes and bacteria from reproducing. A TeleWeir Gate prevents debris from re-entering into your water system.
Hydro-Pro Swim-Mill + Resistance I™
Endlessly walk, jog or swim at BEGINNER levels of resistance.
Seating
Enjoy lounge or bench style seating; keep an eye out for the cool off seat after your exercise.
Exclusive Velocity™ X Jets
Strategically placed to hit exact pressure points, which will allow your muscles to decompress. Jets are adjustable at your convenience.
Twin Pure Silk™ System
Using Dual Ozonators with Mazzie Injectors Mixing Chambers, it kills microorganisms and prevents them from reproducing. No chemicals are added to the water, and won’t interfere with the oxidation process.
Hydro Steel Foam
This high-density foam is added to support the plumbing underneath so nothing gets out of place.
Fibersteel™ Construction
Patented 7-layer laminate system reinforced with steel and wood. This combination creates one of the strongest shells in the world.
Hydro-Armor™ Spa Cover
Our spa cover is built with a tapered edge and has a downward angle from the center, which prevents precipitation from pooling. Made from 100% marine-grade with a vinyl top, filled and supported by 18-gauge steel C-Channel beams.
Cal Preferred™ Cabinet Panels
These highly-durable panels mimic the look of natural wood and are standard on all Cal Spas hot tubs in a variety of colors that complement any backyard landscape.
Thermo-Shield™ Side Panel
Our cabinet walls contain premium insulation that is completely recyclable and produces less waste than traditional urethane foam. Additionally, it does not block passage to the spa.
Pressure Treated Wood Cabinet Frame
Our cabinet frames are treated to resist rot, corrosion and insects. Constructed using 1″ galvanized steel fasteners, corner gussets, and vertical angle bracings for added beam support.
Cal Spas TP-700
A modern intuitive electronic hot tub control system designed to easily switch between settings. Including in-depth features, vibrant colors, user feedback and response.
Whisper Hot™ 5.5 KW Titanium Heater
Titanium Element in calcified Tube Titanium has become the solution to hot tub heater longevity, and has long been the best defense against chemical and mineral abuse.
Eliminator High Performance™ Pump
We have the most reliable motors in the industry. With less moving parts, these motors feature two independent winding speeds and a reverse-flow cooling system. Built to last a lifetime!

Optional Features of the Freestyle F-1437 Swim Spa

LED Dual HydroStreamers Plus™ with Valve
Up to eight breathtaking LED Hydro-Streamers™ instantly turn any backyard into a beautiful tropical paradise option on selected model.
Full Foam Insulation
By adding full foam into the spa structure, water is preserved so the heat does not release. This will reduce the time that it takes to heat and maintain water temperature.
Freedom™ Sound System
Includes Bluetooth, Powered Subwoofer and Cube Speakers. Bluetooth technology lets you control your music through your smart device from anywhere inside, or outside your Cal Spas Hot Tub.
WiFi Module
Using Wi-Fi allows you to control your spa from anywhere in your home. Turn your spa on and off with ease. Control your filter cycles, the temperature and the pumps. You choose!
Wifi Connect™ System
Upgrade your Wifi connection to direct RF (Radio Frequency). Your spa will have its own local IP address and can talk to other smart appliances and devices like Alexa and can be controlled and monitored anywhere around the world via the built-in Cal Spas app
