Air Handling Units and Fan Filter Unit are two common types of air handling equipment that differ significantly in function, application scenarios and construction.
Function: AHU is mainly used to treat air, including air filtration, heating, cooling, humidification, dehumidification and air circulation.
Uses: Widely used in commercial buildings, industrial facilities, hospitals, hotels and other places where centralized air treatment is required.
Characteristics: AHU is usually used in conjunction with central air-conditioning systems and is responsible for transporting treated air to each room through ducts.
Function: FFU is mainly used for localized air filtration, providing clean air through built-in fans and HEPA or ULPA.
Uses: Commonly used in clean rooms, laboratories, electronic manufacturing workshops, pharmaceutical production workshops and other places with very high requirements for air quality.
Features: FFU usually installed on the ceiling of cleanrooms to deliver filtered clean air directly to the work area.
Includes components such as fans, filters, heating/cooling coils, humidifiers, and dehumidifiers.
Usually large in size and need to be connected to the air duct system.
Can handle a large range of air volume, suitable for large area air conditioning.
Mainly consists of fans and high-efficiency filters, compact structure.
Smaller volume, usually installed independently, does not require complex ductwork.
Suitable for air purification in small or localized areas.
Capable of handling a wide range of air parameters such as temperature, humidity and cleanliness.
Suitable for places that require total air conditioning.
Mainly focuses on the cleanliness of the air, with a filtration efficiency of 99.99% or more.
Suitable for places with very high requirements for cleanliness, but with limited ability to regulate temperature and humidity.
Complicated to install and needs to be used in conjunction with ductwork and central air conditioning systems.
Higher maintenance cost, need to clean the filter, check the coil and fan regularly.
Simple installation, usually directly embedded in the Cleanroom ceiling.
Maintenance is relatively simple and mainly involves regular replacement of high-efficiency filters.
Commercial buildings, like office buildings, shopping malls, hotels, etc.
Industrial facilities, like factories, workshops, etc.
Hospitals, schools and other large public places.
Clean Rooms, such as the electronics manufacturing, pharmaceutical production, biological laboratories, etc.
Localized areas with high cleanliness requirements such as operating rooms, chip production lines.
