Ceiling Fan Coil Unit Experts' Buying Guide and Price List
Ceiling fan coil units come in various appearances, capacities, and build qualities (noise level and air volume produced).
There are different types of ceiling fan coil units, all of which are classified in this category due to their installation above the false ceiling of building units.
Types of ceiling fan coil units include built-in ceiling fan coils (suction from below - suction from behind), surface-mounted ceiling fan coil units, with plenum filter and without plenum filter, which are widely used in construction projects with air flow capacities of 200 to 1200 CFM (depending on the type of ceiling fan coil).
Among these, cassette ceiling fan coil units are also classified separately due to their wide variety and different structure compared to other ceiling FCUs.
Ceiling Fan Coil Unit Capacity Determination
As mentioned, ceiling fan coil units have the most variety in terms of ventilation capacity and are offered in capacities of 200 to 3000 CFM based on the type of fan coil.

Different Types of Ceiling Fan Coil Units
Ceiling fan coil units differ from each other in terms of appearance, installation position, and pressure tolerance, and they create the following categories:
1. Concealed Ceiling Fan Coil Unit
The concealed ceiling fan coil, either with or without a cabinet, is the best-selling type of ceiling fan coil, produced and offered by many manufacturers such as Tahvieh, Sarmā Afarin, Yekta Tahvieh Arvand, Saran, Saraval, DamaTajhiz, Green, etc.
This type of fan coil unit is installed within the false ceiling, with only the air outlet grilles visible and exposed in the ceiling; for this reason, concealed ceiling fan coils are considered one of the most commonly used options in interior design.
Concealed ceiling fan coils are available in airflow capacities ranging from 200 to 1200 CFM to meet the cooling and heating needs of buildings of various sizes, and they are mostly suitable for residential, office, commercial, and hotel projects.
Since this model is installed within the false ceiling, its noise level is lower compared to surface-mounted ceiling models; however, maintenance and repair require better access due to its placement inside the ceiling.
Concealed ceiling fan coils have two models based on how they receive air: rear suction and bottom suction. The main difference between these two models lies in the location of the return air entry into the fan coil, which affects the device's performance, installation method, and space conditions.
1.1. Concealed Ceiling Fan Coil Unit - Rear Suction
In this model, the ambient air is drawn in through a grille located at the back of the fan coil, and after passing through the filter and cooling or heating coils, it is blown into the environment.
Rear suction fan coils are typically used when there is enough space behind the unit to provide return air from the environment. The features of the concealed ceiling fan coil with rear suction include:
Higher efficiency due to more uniform air entry into the device. Suitable for spaces where there is enough room behind the false ceiling for air suction. It has a relatively quieter operation compared to bottom suction models, as the return air enters the fan through a more direct path. The possibility of using various filters to improve the quality of incoming air.
1.2. Concealed Ceiling Fan Coil Unit - Bottom Suction
In this model, air is drawn in from the bottom of the fan coil, and after passing through the filter and coils, it is distributed through outlet grilles in the environment.
Bottom suction fan coils are designed for spaces where it is not possible to provide return air from the back, such as low ceilings or places where the space behind the unit is blocked. The features of the concealed ceiling fan coil with bottom suction include:
Suitable for spaces where the height of the false ceiling is limited and air suction from the back is not possible. Easier installation and repair compared to the rear suction model, as the filters and components of the device are accessible from below.
An ideal option for places that require faster air circulation. It may have a higher noise level compared to the rear suction model, as air enters the device directly from the bottom.
2. Exposed Ceiling Fan Coil Unit
Today, exposed ceiling fan coil units are less popular among manufacturers and consumers than other types of fan coil units.
An exposed or surface-mounted ceiling fan coil unit, which is also known as fan coil with cabin, is designed for surface installation.
It should be noted that some manufacturers, such as Green, introduce this type of fan coil unit to the market with the ability to install on the ceiling and the floor, under the name ceiling-floor fan coil. They are produced and supplied in various ventilation capacities to meet different needs.
3. Cassette Ceiling Fan Coil Unit
The cassette ceiling fan coil unit is one of the most commonly used types of ceiling fan coils, produced and offered in capacities ranging from 300 to 1,500 CFM with its unique design compared to other ceiling fan coils.
Cassette ceiling fan coil units are installed recessed in the false ceiling, with only their visible panel being noticeable; for this reason, they occupy less space and have a desirable appearance. Installing a cassette fan coil system, in addition to the false ceiling suitable for placing the unit, also requires the provision of water and electrical piping.
This model of ceiling fan coil unit is usually considered an ideal option for spaces that appearance is very important such as offices, hotels, stores, and commercial buildings due to their uniform air distribution in the environment.
In fact, it can be said that cassette fan coil units are used in places that require a combination of high efficiency with a more suitable appearance.
Other features of the cassette fan coil include the presence of a drain pump for discharging condensed water, which prevents water from accumulating inside the unit.
Additionally, one of the main advantages of this fan coil is its quiet operation and optimal air distribution; however, its installation cost is usually higher than that of other ceiling fan coil models and requires a suitable false ceiling. Cassette FCUs are categorized into three types based on the number of airflow directions:

3.1. One-Way Cassette Ceiling Fan Coil Unit
The one-way cassette fan coil directs air from only one side into the space and is mostly used in areas where a specific direction for air distribution is sufficient (such as next to walls, small offices, conference rooms, or small stores).
3.2. Two-Way Cassette Ceiling Fan Coil Unit
The two-way model of the ceiling cassette fan coil directs air from two opposite directions into the space and is usually used in rectangular areas or long corridors that require balanced air distribution.
3.3. Four-Way Cassette Ceiling Fan Coil Unit
The four-way cassette fan coil is one of the most commonly used cassette models that distributes comfortable air from four different directions in the space.
This model, with its uniform air distribution, increases ventilation efficiency and creates a consistent temperature in the environment.
Ceiling Fan Coil Unit Components
Generally, ceiling fan coils have similar components and functions. The main components of a ceiling fan coil include a water coil, fan, electric motor, drain tray, filter, air vent valve, and other connections and equipment that are placed inside a galvanized sheet metal body.
In this system, air passes through the copper coil containing cold water in the summer and the coil containing hot water in the winter, providing cool and warm air in different seasons.
It is worth mentioning that the water flowing in these fan coils is cooled by central chiller systems or mini chillers in the summer and heated by the combi boilers or hot water boilers in the winter.
Buying Ceiling Fan Coil Units
As mentioned, ceiling fan coil units have the most variety; therefore, to select and purchase a ceiling fan coil, it is essential to consult with the experts at the DamaTajhiz HVAC store to choose and buy the most suitable type of fan coil unit for your project.
However, in general, when purchasing a ceiling fan coil unit, you should pay attention to parameters such as the type, capacity, noise level, dimensions, type of fan and electric motor, number of coil rows, and whether the fan coil has two or four pipes.
The Price of Ceiling Fan Coil Units
The price of ceiling fan coil units varies based on type, brand, capacity, and quality of construction, and you can make the best choice from among hundreds of ceiling fan coil models offered by the DamaTajhiz HVAC, according to your project conditions.
It is important to note that the prices of all ceiling fan coil units offered in the DamaTajhiz HVAC store are up-to-date, and the discounts desired by consumers have been considered in these prices.
