A duct fan for extracting 100 mm provides forced outflow of the air mixture from the room. Its use is relevant for getting rid of extraneous odors, high humidity, and also to create a comfortable microclimate. The considered modifications are mounted directly in the duct channel, they are equally effective in the kitchen, in the toilet or in the bathroom.
Differences in body shape
One of the criteria by which duct fans for drawing 100 mm differ is the configuration of the body part. The following modifications are distinguished:
- Round variations are designed for installation in ventilation ducts of a similar shape, are the most common in their class.
- Rectangular models are designed for installation in ventilation with a square or rectangular cross-section. Most of these are industrial modifications with increased operational capacity.
- Square samples are almost identical in their intended use to rectangular variants; they are also often used for industrial purposes.
Design features
Another significant difference is the design features. Axial options are equipped with a cylindrical body. Inside it is located the fan itself with blades that aggregate with the axes of the electric motor. This design facilitates the movement of air along the axis of the device. At the entrance, there is usually a special manifold that increases aerodynamic performance. The main advantages of such models include high efficiency, which allows to process at least 100 cubic meters of air mixture per hour.
In addition, the axial duct fan for extracting 100 mm is easy to install, which contributes to its frequent use in the ventilation of apartments and private houses. Among the disadvantages are the increased noise level (about 40-50 dB) and low power parameters.
Radial and centrifugal models
The radial unit is equipped with a spherical body, inside of which is placed a wheel with blades. Its rotation causes air to move in a spherical direction, which allows compressing air masses under the influence of centrifugal forces, after which the air enters the atmosphere. The shoulder parts can be directed back or forward. In the frontal version, the operation power of the duct fan for hoods is increased, and the design with a rear bend saves more than 15 percent of energy. The radial duct fan for the hood has compact dimensions, easily mounted on any branch of the air system.
Centrifugal aggregates are relatively new variations. Nevertheless, they managed to gain great popularity among users. Models are perfect for installation in rooms with an area of over 15 square meters. A powerful channel silent fan for extracting 100 mm is convenient in that it can be placed not only in front of the air fence, but also in the middle of the ventilation shafts.
Special Modifications
Specialized models have also been developed that are designed to remove smoke and protect against explosion. Axial smoke exhaust options are designed for air movement with a certain percentage of impurities. Modifications Silent - duct fans for the extraction of 100 mm, just work on this principle. They are great for active kitchens and industrial premises. These models have a large indicator, in a short period they remove smoke and steam from the room.
Separately, it is worth noting the explosion-proof ventilation system. It is a fan, the main purpose of which is the forced cleaning of the hood with explosive or combustible components. This option is optimally suited for special applications. It is used very rarely in everyday life.
What to consider when buying?
Before purchasing a duct exhaust device, a number of parameters should be considered.
The main criteria:
- The performance of duct fans is 100mm. Calculating this aspect is easy. It is necessary to multiply the volume of the room by the frequency of air exchange. The last parameter is responsible for the number of airflow updates per hour. For example, for a bathroom that three people use, it will be 6, and for a toilet operated by more than three people, its number rises to 10.
- If you want the most silent device, choose a device that has this parameter in the range of 90-100 cubic meters. m / hour.
- Also consider motor operation and vibration when moving air masses. The optimal indicator is a value of 25 dB or less. With higher parameters, the device for residential premises is not suitable.
If you install a special silencer behind the body of the unit, you can significantly reduce the noise emitted. Additionally, you can protect yourself from extraneous sounds when the fan is operating by using soundproofing materials to finish the ventilation shaft.
The price of a duct fan for extracting 100 mm
The cost of an air extraction unit depends on several aspects. Among them:
- Dimensions.
- Power.
- Case material.
- Manufacturer.
For example, devices in a metal case will cost an order of magnitude more expensive than plastic counterparts. The price of a conventional exhaust fan starts from a thousand rubles. More advanced and powerful models will cost 2-3 times more expensive, as well as modifications of an industrial design, as well as variations equipped with additional sensors and regulators.
Care and maintenance
Like any equipment, axial duct fans 100 and their analogues require appropriate care. Regularly carry out preventive maintenance and cleaning of the device. Particular attention should be paid to the fan blades and the ventilation grill. They clog faster than other elements.
After installing any modification, reviews are advised to check the system for leaks at the joints. It is in the cracks that a mass of dirt, dust and bacteria accumulate. The cleaning process of the device is carried out mechanically or chemically. Simply put, use rags, brushes, or special cleaners. For overhaul, it is recommended to dismantle the fan, disassemble it, thoroughly clean all parts. In designs with a replaceable filter, it must be replaced within the time specified by the manufacturer. The cleaning frequency can be reduced if an additional fine mesh is installed at the inlet of the duct.
Device installation
Before installing the duct fan, check the health of the ventilation system. According to reviews, this is not difficult. Bring a lit match or piece of paper to the ventilation hole. If the flame deflects toward the exhaust, and the paper is held in by retracting pressure, then the system is functioning normally. Otherwise, you will have to purchase an exhaust fan . Then you need to determine the installation location. Reviews recommend mounting the unit under the ceiling, as hot and humid air masses rise up.
In conclusion
Forced air is very important in rooms with high humidity or dustiness and unpleasant odors. As a rule, duct fans for hoods are mounted in the kitchen, bathroom, toilet. The choice of device type depends on the characteristics of the room, ventilation and user requirements.
