Carrier’s Aero 39M air handlers provide advanced technology and custom features in a streamlined, easy to install package. Indoor and outdoor units are available to handle a wide variety of applications. Units can be equipped with HEPA filters, stainless steel quad-sloped drain pans, AgION™ antimicrobial coating and other options. The 39M unit’s double-wall casing allows panels to be easily cleaned without damaging the insulation inside. Available fan options include forward-curved, airfoil, and plenum fans for extra quiet operation. Factory-installed controls maintain airflow and ventilation requirements while helping to prevent coil freeze-up, excessive humidity and poor indoor air quality (IAQ). Carrier’s AHUBuilder® software makes selecting and optimizing the 39M air handler easy.
