The SC41 is the most power unit in our fleet of portable office air conditioners. It has very strong fans to aid air circulation, and also has the added benedit of being able to use up to 4 metres of exhaust hose. It is suitable for cooling larger office spaces of up to 40 square metres and has the benefit of having no condensate tanks to empty, which means this unit can be left running 24 hours a day, 7 days a week. The stronger fans mean this unit is slightly noisier than others, but will certainly help to keep your staff cool
