The KoolBase MSC407NE Spot Cooler is an 8,500 BTU, 0.7 ton mobile spot cooler that runs on 115V at up to 1050W, with cool, fan and dehumidify modes and a built-in evaporator for most of its condensate. For more models, see our Portable Spot Coolers page.
Our Verdict
The MSC407NE brings a proper spot cooler design to home workshops and garages without industrial pricing. Its power draw fits a household circuit, and the built-in evaporator means far less tank emptying.
It weighs 88 pounds and has a single outlet, so it suits one work area rather than a whole garage.

Design
The unit rolls on wheels between indoor and outdoor spaces and measures 17 by 15 by 31 inches. It needs no assembly.
The built-in evaporator removes most of the condensate, and a dehumidification function helps in damp garages and basements. The refrigerant is R410A.
Controls
There are two modes beyond dehumidifying: cooling, and a fan mode for plain air circulation on milder days.
KoolBase lists the electrical details clearly: 115V, a load current of 8.8A on high and 7.9A on low, and 1050W on high and 950W on low.
Placement Tips
Put the cold air outlet within a few feet of the people or equipment you want to cool, and point the hot exhaust away from them. Indoors, run the exhaust to a drop ceiling, an open doorway or an exterior vent, otherwise the unit only moves heat around the room.
Leave open space around the intake so the unit can breathe, keep it on a level floor, and plug it straight into a grounded outlet on a circuit that is not shared with large tools. Outdoors, keep it out of standing water and under a roof or canopy unless the listing gives it a weather rating.
Running Costs and Care
Running cost depends on how many hours a day the compressor runs and on your electricity rate. Spot coolers draw far more power than a fan but far less than cooling a whole building, which is why they make sense for one work area or a short summer peak.
Clean or wash the air filter often, especially in dusty shops, and check the condenser coil for dirt and lint at the start of each season. Empty the condensate tank or check the drain line regularly, and before storing the unit, run it in fan mode to dry it out and drain all remaining water.
How It Compares
Against the Uninex KoolZone N407-TC, the KoolBase costs less and is aimed at consumers, while the N407-TC is industrial grade with a published efficiency rating.
Against the KoolBase MSC1800NE, the MSC407NE cools more, while the MSC1800NE is smaller, lighter and draws less power.
