Floor to Floor Air Handling Unit

As a high-efficiency, space-saving HVAC core equipment, the Floor to Floor Air Handling Unit (FFAHU) is specially designed for mid-rise, high-rise buildings, commercial complexes, office buildings, hospitals and industrial plants. It adopts a vertical or floor-mounted integrated design, which can be flexibly installed on each floor to realize independent air treatment for each floor, effectively solving the problems of uneven air supply, high energy consumption and difficult maintenance of traditional centralized air handling systems. With its compact structure, efficient air treatment, flexible configuration and easy installation, it has become the preferred equipment for floor-by-floor HVAC solutions, creating a comfortable, clean and energy-saving indoor environment for users.

Core Advantages

• Floor-by-Floor Independent Control, Precise Comfort: Each unit is independently installed on a single floor and can be controlled separately, realizing independent adjustment of temperature, humidity and air volume according to the usage needs of different floors (such as office floors, commercial floors and residential floors). It avoids the problem of uneven temperature caused by centralized air supply, ensures that each floor maintains a comfortable indoor environment, and meets the personalized needs of different users, while reducing energy waste caused by unified operation of the whole building system.

• Compact Structure, Space-Saving Installation: Designed with a slim and compact structure, the unit can be flexibly installed in small spaces such as floor equipment rooms, corridors or corners, without occupying a large area. Most models can pass through standard door openings, and larger units can be split into sections for transportation and installation, greatly reducing the difficulty of installation in high-rise buildings and saving valuable building space. The unit body adopts a tenon double-column structure, ensuring ultra-high strength and ultra-low air leakage rate as low as 0.03%, effectively improving air treatment efficiency.

• High-Efficiency Air Treatment, Clean and Healthy: Equipped with multi-stage filtration system (primary, medium and high efficiency filters), it can effectively filter dust, bacteria, PM2.5 and other harmful substances in the air, with a filtration efficiency of up to 99.97%. It is also optional with humidification, dehumidification and heat recovery functions, realizing precise control of indoor air humidity (40%-60% RH) and ensuring fresh and clean air. For special scenarios such as hospitals and laboratories, it can be customized with high-efficiency HEPA filters to meet strict air cleanliness requirements.

• Energy-Saving Operation, Low Operating Cost: Adopting high-efficiency frequency conversion fan and energy-saving heat exchanger, the unit can automatically adjust the fan speed according to the actual air demand, reducing energy consumption by 25%-35% compared with traditional fixed-speed air handling units. The optional heat recovery module has a heat recovery efficiency of more than 80%, realizing cascade utilization of energy and further reducing operating costs. It fully complies with global energy conservation and environmental protection standards and green building requirements.

• Easy Installation & Maintenance, Low Later Cost: The unit adopts a pre-engineered integrated design, which can be quickly installed on-site with plug-and-play operation, greatly shortening the construction period. The floor-mounted installation makes daily maintenance (such as filter replacement, equipment inspection) more convenient, without the need for high-altitude operations, reducing maintenance difficulty and safety risks. The unit is equipped with a complete intelligent control system, which can realize remote monitoring and fault alarm, further reducing later operation and maintenance costs.
