Air Masters - Going Green

Air Masters Makes a Commitment to a Green Environment

Air Masters has installed a 75kW solar electric (photo-voltaic) system at our building in Fenton, MO.  This system will produce about 18%-20% of our power requirements.  Solar is one of the best ways to decrease your carbon footprint. The Midwest is powered largely with coal, so each kWh produced from a solar system saves one pound of coal from being burned.  The estimated environmental benefits of the system are:

Tons CO2 / 25 years 1,425
Pounds of coal / year 90,000
Median car miles offset / 25 years 2,589,273

Beyond cleaner air and lower carbon emissions, this solar system will also decrease our energy costs.
