Ultra-quiet operation is the hallmark of LG’s new line of PTAC products. Low decibel levels and an
outstanding sound-prevention rating make this your best choice for a quiet environment. And with
efficiency ratings up to 12.5 EER, these units are also your energy efficient choice.
Other features include standard connections for remote thermostat and front desk controls. Gold Fin
™
technology protects the unit from the corrosive effects of outside air and extends the operating life of PTAC
models. And the industry standard size makes installation easy and economical.
