Ducted Fan Coil Unit Experts' Buying Guide and Price List
Ducted fan coils are a type of ceiling fan coil that are usually installed in the false ceiling of buildings and transfer conditioned air into the desired environment through ductwork.
In general, ducted fan coil units with various capacities from 600 to 3000 CFM are produced and offered in two types of "return air from behind" or "return air from below" (horizontal and vertical) and with the possibility of fresh air intake, under different Iranian and foreign brands.
Therefore, due to the high air delivery capacity of ducted fan coils, these devices are usually used for spaces with large areas, such as sports halls, beauty salons, medical centers, cinemas, building lobbies, etc., to provide the appropriate temperature for the air conditioning system.

Ducted Fan Coil Unit Advantages
Ducted fan coil units are a suitable option for air conditioning buildings that need uniform air distribution, reduced piping for the cooling and heating system, environmental beauty, and energy savings. The advantages of ducted fan coil units are:
Uniform air distribution: Ducted fan coil units distribute cold or hot air evenly throughout all spaces and prevent the creation of hot or cold spots in the environment due to the use of ductwork.
Possibility of hidden installation and maintaining the appearance: These systems are usually installed in false ceilings or hidden spaces, so they do not affect the interior decoration, and the aesthetic appearance of the environment is preserved.
Reduced noise and operating sound: Due to installation in ceiling spaces and the use of ducts, the noise generated by the fan coil is minimized, creating a quiet environment for residents or employees.
Flexibility in design and implementation: Ducted fan coil units can be implemented in various buildings and with different designs. It is possible to choose the appropriate capacity for each space and also adjust the temperature for different areas.
Increased indoor air quality: In ducted fan coil units, it is possible to install various air filtration filters, which improve the quality of incoming air, reduce dust, and prevent pollutants from entering the indoor environment.
Possibility of connection to smart systems: Some advanced models of ducted fan coil units have the ability to connect to building management systems (BMS), which helps to better control the temperature and reduce energy consumption.
Different Types of Ducted FCU in Terms of Static Pressure of the Ventilation Fan
Ducted fan coil units are divided into three main categories based on static pressure: low pressure ducted fan coil, medium pressure, and high pressure. Static pressure is actually the force that the fan of the device applies to overcome the resistance of the ductwork system.
The longer and more complex the ductwork path, the stronger fan with higher static pressure is needed. In the following, we will describe each of these categories:
1. LSP Ducted Fan Coil Unit
Low static pressure ducted fan coils are designed for small and medium spaces that require short ductwork.
This type of ducted fan coil, due to its low static pressure, is usually used in residential buildings, small offices, and spaces that require simple air distribution.
Since the fan power in low static pressure ducted fan coils is less than other models, these fan coils have low energy consumption and produce little noise, but they are not suitable for large spaces or long ductwork.
LSP Ducted Fan Coil Unit Features:
Fan static pressure between 0 and 50 Pascal
Suitable for small and medium spaces
Requires short and simple ductwork
Low noise level
LSP Ducted Fan Coil Unit Advantages:
Low energy consumption
Easy installation and lower cost
Low noise and quiet operation
LSP Ducted Fan Coil Unit Disadvantages:
Limitations in ductwork length
Inability to provide sufficient air for large spaces
2. MSP Ducted Fan Coil Unit
Medium static pressure ducted fan coils are more suitable for office buildings, commercial buildings, hotels, and stores that require medium ductwork.
The higher static pressure of this type of ducted fan coil compared to the low-pressure model allows for better and more uniform air distribution inside the space.
Medium static pressure ducted fan coils strike a good balance between energy consumption, air distribution capacity, and noise level, making them a practical option for medium-sized spaces.
MSP Ducted Fan Coil Unit Features:
Static pressure between 50 and 150 Pascal
Suitable for office buildings, commercial buildings, and hotels
Possibility of better and more uniform air distribution
Ability to install in false ceilings with medium ductwork
MSP Ducted Fan Coil Unit Advantages:
Possibility of longer ductwork compared to the low-pressure model
More uniform air distribution
Suitable for medium-sized spaces
MSP Ducted Fan Coil Unit Disadvantages:
Higher energy consumption compared to the low-pressure model
Higher noise production
3. HSP Ducted Fan Coil Unit
High static pressure ducted fan coils, or high pressure, are more suitable for large buildings, hospitals, conference halls, and shopping malls that require extensive air distribution.
Due to the high static pressure, it allows the use of long and complex ductwork. High static pressure ducted fan coils have a stronger motor and fan, so they distribute more air in the space, but they also have higher energy consumption and noise levels.
HSP Ducted Fan Coil Unit Features:
Static pressure over 150 Pascal (usually between 150 and 300 Pascal)
Suitable for large buildings and public spaces
Possibility of using long and complex ductwork
Stronger motor and fan for more air distribution
HSP Ducted Fan Coil Unit Advantages:
Possibility of air distribution in large spaces
Ability to connect to multiple air distribution vents
High-performance power
HSP Ducted Fan Coil Unit Disadvantages:
High energy consumption
Higher noise production
Higher installation and maintenance costs
Ducted FCU Vs. Concealed Ceiling FCU
The difference between ducted fan coil and concealed ceiling fan coil is in their air distribution method, capacity, and installation:
Capacity: Concealed ceiling fan coil units are usually used in lower capacities (200 to 1,200 CFM) for smaller spaces such as residential units, hotel rooms, and office spaces.
In contrast, ducted fan coils with higher capacities (600 to 3,000 CFM) distribute conditioned air to multiple spaces through ductwork and are more commonly used in large buildings, hotel lobbies, commercial centers, and hospitals.
Installation and Air Distribution: Concealed ceiling fan coil units usually do not require ductwork, but in some cases, they can be connected to short and limited ducts. This type of fan coil is installed directly inside the false ceiling and distributes air directly into the space through one or two vents.
Although it does not require an extensive ductwork system compared to ducted fan coils, in some applications, a short duct may be used for multiple vents for better air distribution. In contrast, ducted fan coils must have ductwork to deliver conditioned air to multiple points in a building.
