IE5 Permanent Magnet Motor Supply Fan
The H3 and V3 Series feature supply fans designed around new permanent magnet motor technology. These hybrid motors incorporate a synchronous reluctance rotor with permanent magnets to achieve an International Efficiency (IE) rating above IE5, the highest level of efficiency available today. The advantages of the Hybrid Permanent Magnet Motor are even more significant at lower fan speeds, where variable air flow fans operate during a majority of the time.
NEMA (National Electrical Manufacturers Association) motor frames are available in certain selections.

Construction and Serviceability
Internal Control Panel (H3)
The internal control panel centralizes all low voltage controls within the air handling unit. For H3 Series units, blower access can be gained through the top of the unit, and all three access points share interchangeable duct flanges and access panels.
Removable Internal Control Panel (V3)
The removable internal control panel keeps all low voltage controls internal to the air handling unit and simplifies maintenance by providing single-side access to all components. This versatile panel section can be easily detached by releasing quick connects and unbolting four bolts, streamlining maintenance and serviceability. V3 Series units offer blower access through the left or right access depending on unit orientation selection.
External Control Panel
An optional external control panel for both H3 and V3 provides additional space for electric heat controls and various control features and options.
Description: Optional external control panel.
Lower Maintenance Cost
Enjoy hassle-free maintenance with service access doors featuring lockable quarter-turn handles, LED service lights in the control panel, and labeled components with color-coded wires and wiring diagrams. These features simplify the servicing process, saving time and effort.
Reliability
H3/V3 air handling units are crafted for longevity with construction features like double-wall rigid polyurethane foam panels and sturdy access doors. Factory-engineered, designed, and installed options provide inherent reliability, surpassing field-installed add-ons. AAON's robust air handling solutions deliver peace of mind and lasting performance.
Ease of Installation
Units are designed for convenience. Engineered to pass through standard 36-inch wide by 80-inch tall doors, they are ideal for new installations and retrofit applications. The unit design streamlines the installation process with components like E cabinet filters, energy recovery wheels, and mixing box units that can be shipped in a split configuration.
Increased Thermal Resistance
Double wall rigid polyurethane foam-injected cabinet panels increase thermal resistance, reduce air leakage, and attenuate radiated sound. A thermal break reduces heat transfer between interior and exterior metal cabinet walls.

Configurability
Single Zone VAV
A single zone VAV system utilizes variable capacity or variable speed compressor technology, along with modulating controlled supply fans, to accurately control cooling and humidity levels within the space. This is a great option for applications with varying sensible and latent loads.
Makeup Air Capability and Dedicated Outdoor Air System (DOAS)
Improve airflow and air quality by selecting a unit with makeup air capabilities and low leakage AAON economizers, allowing up to 100% outside air. This can be achieved with the use of AAON low leakage economizers. Adding modulating reheat makes the unit DOAS certified, providing accurate humidity control for the space.
AMCA Certified Low Leakage Dampers
Factory-installed, sensible or enthalpy, gear-driven economizers allow for free cooling. Gear-driven economizers eliminate the excess play and bind that occurs with linkage-type economizers. Standard AMCA certified and labeled AAON low leakage dampers meet the California Title 24 damper air leakage requirement.
Air Handling Unit Options
AAON H3/V3 Series air handling units can be configured as air handling units with chilled water or hot water coils. Gas, electric, and steam are also options for heating control. These units can be paired with a remote condensing unit set up in a different location.
Wide CFM Range & Static
H3/V3 Series air handling units offer a broad capacity range, spanning from 450 to 10,000 cfm. These units feature overlapping cabinet sizes, ensuring a precise match to specific requirements. Thanks to their backward-curved plenum fans, they also deliver excellent static pressure control, offering flexibility in various system setups.

Low GWP Refrigerant
AIM Act Compliant
The AIM Act of 2020 empowered the U.S. Environmental Protection Agency to manage Hydrofluorocarbons (HFCs) and regulate refrigerants based on global warming potential (GWP). GWP was developed to compare refrigerants' impact on global warming. The final ruling mandating all new air conditioners to use refrigerants with a GWP below 700 is anticipated to begin January 1, 2025.
AAON has thoroughly researched and tested low GWP refrigerants and selected R-454B for its similarity to R-410A in capacity and properties, requiring less product redesign. With a GWP of 466, R-454B is well below the upcoming regulation limits.
AAON selected R-454B, a sub-500 GWP refrigerant, to drive the industry towards a cleaner and more sustainable future.
Heat Pumps
The H3/V3 Series offers a split system heat pump configuration that allows matching with an air-source heat pump condensing unit for energy-efficient heating and cooling.
Air-Source Heat Pump
Air-source heat pumps use the outdoor air as the heat transfer medium. This system provides heat pump efficiency benefits and does not require a water loop.
Energy Efficient Split Systems
AAON split systems, when paired with their condensing units, deliver consistent comfort while keeping energy consumption low. The combination of double wall foam-insulated construction and direct-drive backward-curved plenum fans sets a high standard for performance, ensuring both efficiency and comfort.
Description: AAON H3 and V3 Series air handling units configured as split systems.
Indoor Air Quality
The quality of air inside a building impacts the health and cognition of occupants. AAON standard design and rooftop equipment options improve indoor air quality.
Filtration
ASHRAE recommends using a minimum of MERV 13 filters to effectively trap viruses. This option is available on all sizes of rooftop equipment, and the standard backward-curved supply fans are capable of handling the additional static pressure associated with higher-quality filtration. AAON offers up to MERV 14 pleated air filters.
AAONAIRE® Energy Recovery Wheel
Sensible-only or enthalpy energy recovery wheels can be used to pre-condition the outside air, which can greatly improve energy savings and reduce unit operating costs, especially on makeup air units. Energy recovery wheels are offered in polymer or aluminum construction with removable segments for quick cleaning.
Description: AAONAIRE Energy Recovery Wheel component.
Energy Recovery Wheel
