Modular Air Handlers

AAON M2 Series air handling units provide
an ideal solution for new and replacement
applications with its modular construction
and premier factory installed features. The
serviceability, quiet operation, reliability,
premium eciency, and rugged construction
allow M2 Series air handling units to
expertly t the needs of your specic job
requirements. These units reect the proven
reliability and engineering excellence from
AAON, the premier manufacture of heating
and cooling products.

Superior Features

• Double wall rigid polyurethane foam injected panel construction
with thermal break reduces air leakage, dampens resonated
sounds, increases thermal resistance, and oers a cleanable air
tunnel ideal for demanding indoor air quality applications.

• Backward curved plenum supply fans are quieter, more energy
ecient, and handle higher static pressure applications than
forward curved supply fans.

• Units can be shipped factory assembled or shipped as individual
modules to meet the installation demands of any application.

• Double-sloped, stainless steel drain pans eliminate standing water
which can support microbial growth and prevents corrosion that
can lead to water leaks and contaminants in the air stream.

• Removable pin hinges, lockable zinc cast handles, and slide out
access to coils and energy recovery wheels provide easy access for
maintenance and cleaning when required.

• Multiple base heights are available that allow ease of installation
and can eliminate the need for a housekeeping pad for condensate
drain trap.

• Labeled electrical components and color-coded wiring match the
unit specic color-coded wiring diagram that is laminated and
permanently axed inside the control compartment.

• Factory run test report, wiring diagram, and Installation, Operation,
and Maintenance manual with startup form are provided in the
control compartment of every unit.

Premier Options

• Available for Constant Volume, Variable Air Volume (VAV), Single Zone
VAV, and Makeup Air applications with up to 100% outside air.

• Water-source or geothermal heat pump congurations with 10-100%
variable capacity compressors for a packaged indoor system and
energy ecient heating.

• Factory installed total or sensible AAONAIRE energy recovery wheels.

• Modulating Hot Gas Reheat humidity control for precise humidity
control necessary to maintain occupant comfort without the
temperature swings common with on/o reheat systems.

• Modulating gas heat with 5:1 turndown and either natural or
LP gas applications with open or separated combustion.

• SCR (Silicon Controlled Rectier) electric heat control for reduced
power consumption, longer heater life, and improved occupant
comfort.

• Multiple high eciency ltration options with up to MERV 14
eciency rating are available with or without monitoring devices.

• Multiple corrosion protection options including 6,000 hour salt spray
tested polymer e-coated indoor coils, CuNi coaxial or SMO 254 brazed
plate refrigerant-to-water heat exchangers, and 2,500 hour salt spray
tested interior and exterior corrosion cabinet protection.

• ECM (Electronically Commutated Motor) driven or VFD controlled
backward curved plenum supply fans for precise air ow control and
reduced power consumption.

• Fixed Plate Heat Exchanger Energy Recovery saves heating and
cooling energy and features extremely low cross contamination. Both
sensible and enthalpy cross-ow heat exchangers are available and
have no moving parts.
