The Portacool Cyclone™ 120 is perfect for smaller settings, yet still delivers an impressive amount of air output. The Cyclone 120 provides mobile, energy-efficient, refreshing comfort to your outdoor or open spaces. Perfect for cooling spaces where traditional methods of cooling are inefficient - small patios, garages, hobby areas or single-stalls. We do NOT recommend this product being used inside homes or closed spaces where no ventilation is available.
