High-Tech Fan for quiet operation. The saw teeth curved blades of the fan are strategically curved and sized to maximize the air flow across the outside coil, minimizing energy consumption and increasing efficiency. The slinger ring throws condensate on the back and sides of the bent coil for additional cooling and reduces the amount of condensate that leaves the unit. Easy-Clean Filter - The KLIMAIRE PTAC pull-out filter offers easy maintenance without opening the intake grille. Just simply slide out the filter for easy cleaning. Activated charcoal filters are also available as an option to absorb airborne orders. Quick Condenser-Coil Cleaning - Easy access to KLIMAIRE Coil technology makes routine maintenance a snap - saving you money. The entire top of the Coil shroud is easily removed. Now, the whole condenser can be cleaned, thoroughly and quickly, which improves heat transfer, maintains capacity and efficiency and significantly extends the compressor and sealed system life. Exceptionally Quiet Operation. Ultra-balanced saw teeth shaped fan blades and dual fan motors assure whisper quiet performance. A very quiet rotary compressor powers this unit for assurance of silent operation.
