M3 Series

The AAON M3 Series Modular Air Handling Units are engineered to handle many difficult applications. Total energy recovery, 100% outside air, and special dehumidification needs are just a few of the applications AAON M3 Series easily handles. Through double wall construction and ultra low leak rates, AAON M3 series air handling units provide economical solutions for comfort cooling and heating.

Applications
  • Air handling unit with chilled water or direct expansion coils from 6,400 - 52,000 cfm.
  • Heating from hot water, steam, and direct fired gas.
  • Split system heat pump with air-source, water-source, or geothermal configurations.
  • Make up air capability, up to 100% outside air, to meet ventilation requirements.
Construction
  • The M3 Series modular design provides easy installation at the job site. Unit modules may be factory assembled to prevent unnecessary lifting at the job site or shipped separately for job site maneuverability.
  • Double wall cabinets utilize thermal breaks and closed-cell polyurethane foam to increase thermal resistance, improve air seals, inhibit microbial growth, reinforce structural integrity, and attenuate radiated sound.
  • Rigid polyurethane foam panels, high quality sealing, and double wall doors save operating costs by reducing the unfiltered and unconditioned air leakage to less than 1% system cfm at 8” static pressure.
  • Selectable base rail height allows for condensate trapping and eliminates the need for a costly housekeeping pad.
  • Double sloped, stainless steel drain pan eliminates standing water that can support microbial growth. A stainless steel drain pan will not corrode and contaminate the air stream.
Features and Options
  • AAONAIRE® energy recovery is factory installed to reduce the operating expenses associated with supplying outside air to buildings. By reclaiming up to 80% of the exhaust air energy, AAONAIRE® energy recovery units maintain comfortable temperatures and humidity during both cooling and heating conditions. AAONAIRE energy recovery wheels are rated to AHRI Standard 1060 and bear the AHRI Certification symbol.
  • Pleated, permanent, cartridge, and bag, filters are available with or without monitoring devices to meet the building’s required indoor air quality. 
  • UV-C lighting is also available inside the cabinet to meet even the most stringent indoor air quality requirements while increasing system performance and longevity by eliminating mold growth on coils.
  • Coils are available with polymer e-coatings, copper fins, and stainless steel casings to minimize corrosion and improve air quality.
  • Modulating hot gas reheat, reclaim coils, and return air bypass can provide the precise humidity control necessary to maintain occupant comfort.
  • Cabinets can have custom interior and exterior paint to enhance aesthetics while improving corrosion resistance and indoor air quality.
  • Hot water preheat systems can be provided to prevent hydronic coil freezing.
  • Cabinet walls are available in stainless steel for superior corrosion resistance or aluminum to decrease unit weight.
  • Perforated, galvanized steel sound attenuators can be installed in the air stream to eliminate operational noise.
Fans and Blowers
  • Fans and blowers are individually selected to match external static, sound, efficiency, and space design criteria as specified. Blowers are backward curved centrifugal plenum style. Blowers with backward curved blades are generally quieter and more efficient than forward curved blowers.
  • Premium efficiency motors, direct drive systems, and variable speed fan control provide high efficiencies and significant operating cost savings.
  • Supply fans, exhaust fans, and return fans are incorporated into fan arrays for redundancy, low turndown, and low noise capabilities.
Controls
  • Unit wiring is completely factory provided with color-coded wires. Units are provided with specific, color-coded wiring diagrams. Diagrams are laminated and permanently affixed inside control compartment access door.
  • Factory provided or customer provided controller can be selected to meet existing or new building control architecture.
  • Factory run test and inspection reports are included in the documentation compartment affixed to the interior of the control compartment access door.
