High-Volume Air Handling Performance
The DAQ09034 provides a nominal airflow of 3,000 CFM through two direct-drive blower motors with five speed selections. Blower performance can vary according to speed selection, external static pressure, and installation configuration, allowing the air handler to be set up for the requirements of the connected duct system.
Heating & Cooling Performance
The DAQ09034 is designed for use with a compatible 7.5-ton cooling-only or heat pump outdoor system. The unit has a nominal cooling capacity of 90,000 Btu/h and uses two thermal expansion valves for refrigerant control. Field-installed electric heat kits are available in 15 kW, 20 kW, and 30 kW configurations to provide supplemental electric heating when required.
Efficient Airflow Design
The DAQ09034 features two 5-speed direct-drive motors and a draw-through centrifugal blower design. Multiple speed selections allow airflow to be adjusted to suit system requirements, while the fully insulated cabinet helps support quiet operation and efficient air handling.
Durable Air Handler & Installation Design
The split air handler configuration is designed for indoor installation and connection to a compatible outdoor condensing unit or heat pump condenser. The DAQ09034 uses a heavy-gauge, reinforced, galvanized-steel cabinet with a fully insulated fiberglass blanket. Horizontal and vertical condensate pans provide installation flexibility, while top-panel entry accommodates both low- and high-voltage connections. The unit supports upflow or left-sided horizontal installation.
Controls & Comfort
The DAQ09034 includes standard transformer and blower relay controls and two 5-speed direct-drive blower motors. Its TXV control system uses two thermal expansion valves to provide refrigerant metering for the two-circuit coil arrangement. When configured with a compatible cooling-only or heat pump outdoor unit and applicable controls, the system provides conditioned airflow for commercial comfort applications.
Commercial Applications
The Daikin DAQ09034 is designed for light commercial applications requiring a 7.5-ton split-system air handler, including schools, hotels, offices, and retail spaces. Its upflow and left-sided horizontal installation configurations make it suitable for commercial installations where equipment orientation and available mechanical-room or service space vary.
Service & Maintenance
The DAQ09034 is equipped with removable access panels designed to make servicing faster and easier. The built-in filter rack accepts a 2-inch filter, providing convenient access for routine filter maintenance. The cabinet also provides top-panel entry for low- and high-voltage connections to support installation and service access.
