Friedrich is a top selling air conditioning brand that has consistent standard dimensions which makes finding a replacement unit quick and easy. The Friedrich ES16N33 features advanced airflow design for quiet, powerful cooling that gets the job done faster. The Friedrich ES16N33 Kühl has been engineered for quiet operation. Materials have been chosen because of their sound-absorption properties and every moving part has been braced and insulated. For example, extra thick rubber grommets absorb vibration and reduce noise inside, while steel inner walls and extra dense insulation block outdoor noise. Rugged hardboard side panels help reduce noise and keep out light. The unique air path is more streamlined, drawing air through the sides, away from moving parts. And our larger discharge vents allow for smoother airflow, delivering maximum conditioned air quietly. It is built tough using heavy gauge steel, solid sleeve tops, large enclosed fan motors and premium components. Vibration and noise isolating technology is included for quiet operation. The ES16N33 features leading energy efficiencies to save on utility costs and help the environment.
