The ultimate in climate control. Don’t mistake that compact size for impaired function, however; the FMS M12 packs the perfect punch of cool, comfortable air to keep your cabin temperate. Thanks to the expertise of FMS engineering and manufacturing team, even the electrical box on this unit only weighs 4.7 pounds.
The FMS 12,000 BTU marine air conditioner also has rotatable blowers and tapers into a V shape to make odd angle discharge installations a breeze. 4″ ducting is used and FMS recommends a minimum of 2, 4″ round supply grills with this installation. This unit will run off of the new Honda EO1000i 1,000 watt portable generator while in cool mode. Another option FMS recommends is to use a Statpower pure sine wave 1,800 watt inverter and 450 amp hours of battery power and you can anchor out for the night.
All M12 models include a digital thermostat, an insulation mounting pad, and an air output collar. Pump not included.
