Using Water only in the MW1 or MW2 & Ice in the WinAire for Spot Cooling will not reduce the interior temperature of a vehicle much, as you need the windows down somewhat for ventilation, therefore hot air is always flowing into the vehicle. This does not matter as you will feel cool air as long as you have the vents within one foot of your upper body for maximum benefit. This is sometimes difficult in a vehicle, therefore the need for the Flex Hose Kit.
You will normally not need the Flex Hose Kit in a Camper,
Boat, Tent, etc. as contrary to a vehicle a portion of the camper
will begin to cool down once you start the MightyKool, therefore
you do not need the cooler that close to you. Even though you
need ventilation the heat does not stream in like in a vehicle.
One reason you might want the Flex Hose Kit is if you are trying to cool two areas some distance from each other like in a Pop Up camper as the bunks are on two opposite sides. For Pets in kennels the Flex Hose Kit is almost a must.
With simple installation either the 2 or 4 Flex Hose Kit allows you to set the Cooling System out of the way directing the Cool Air up to seven feet where you need it the most. Strongly consider the Kit if you must set your Cooling System farther than one foot away from your needs in extreme heat especially in a Vehicle or Aircraft.
The Flex Hose Kit FH2 (right) contains everything needed for two hoses and the FH4 Kit (left below) contains everything needed for four Cool Air Vent hoses. If you have a MightyKool Model with four Cool Air Vents you would only use the front two and close the ones on the side for Flex Hose operations.
First step is to simply remove the two Chrome Cool Air Vents from your MightyKool, install the Hose Adapters in their place and then position the Cooling System in an area out of the way.
Next secure the Flex Hose to the Hose Adapters that replaced the cool air vents, decide where you need the cool air then determine the length of Flex Hose needed. Cut off the excess hose placing the Chrome Cool Air Vents you removed into the end of each Hose. Secure all hoses with the wire ties and you are set to cool.
If you use the Flex Hose Kit the cool air is contained in the hose and only looses one degree per foot in 100-degree ambient air. For our example the 75-degree cool air would be 77-degrees in two feet, 79-degrees in four feet, etc.
Another factor is the Air Velocity effect using a Flex Two Hose system. The normal Feet Per Minute (FPM) velocity from each front outlet vent averages around 1,900 FPM per side on the MightyKool models. There is no loss in velocity using a five feet Flex Hose and the velocity using seven feet only drops about 7%.
Using the Flex Four Hose system yields about 1,300 FPM from each of the four hoses. Compare that with the total of 1,900 FPM coming from the two front vents. Granted that the four hoses will not have the velocity of the two hose system, however 1,300 FPM is plenty of velocity when you direct the cool air properly like you do in a Commercial Airliner.
The Flex Hose Kit Model FH2 contains two hose Adapters that will replace two Chrome Air Vents so that the hose can be attached to the front of the MightyKool. There are two 7-foot flex hoses with sufficient black plastic wire ties to help hold the flex hose where needed. The Chrome Air Vents will attach inside the flex hose end that has been cut to the desired length. The two hose Kit is $47.00 plus 12.00 shipping/handling anywhere in the Continental USA. Prices available upon request to other parts of the world. (No shipping/handling charge when ordering a new MightyKool model at the same time).
The Flex Hose Kit Model FH4 contains two hose Adapters that will replace two Chrome Air Vents so that the hoses may be attached to the front of the MightyKool. There are two 7-foot hoses, two 3-foot hoses, two one foot hoses and sufficient black plastic wire ties to help hold the flex hose where needed. There are two "Y" hose connectors to direct the air into the four hoses plus the two hoses going to the Cooling System. Also included are four new North Star Chrome Air Vents with four adapters to connect to the ends of the hoses. The original Chrome Air Vents are not suitable for the Flex Hose Kit FH4. The four hose Kit is $137.00 plus $14.00 shipping/handling anywhere in the Continental USA. Prices available upon request to other parts of the world. (No shipping/handling charge when ordering a new MightyKool model at the same time).
