How to choose the right exhaust fan

The need to install a fan in the bathroom

A standard bathroom is a room with frequent changes in temperature and humidity, as well as a place where aggressive cleaning agents are used. Without effective air removal, the microclimate becomes uncomfortable, and expensive surface cladding will deteriorate.

There are other reasons for installing a fan:

• steam extraction;
• eliminating dampness and mold on walls and ceilings;
• elimination of unpleasant odors;
• reducing the risks of allergies and respiratory diseases;
• correct direction of air flow in a room without windows.

Important! With only natural ventilation, unpleasant odors and polluted air are inevitable. The line gradually becomes clogged, and a household device minimizes these risks.

Criterias of choice

Do you need a fan for your bathroom? The answer is obvious to those who are tired of fighting the musty aroma and fungus on the walls. First of all, the fan is a modern high-tech device that requires a direct connection to the network to operate. In the process of choosing a device, it is necessary to focus on a number of aspects that are indicated by the manufacturer and are in the product passport.

Safety

It should be understood that we are talking about operating an electrical device in a room with a high level of humidity. That is why this category of products is subject to certain requirements for manufacturing and subsequent use. The housing used must be moisture resistant. Devices that operate on 12-24 volts are unable to cause significant harm, so it is recommended to pay attention to such products, otherwise you will need a step-down transformer, and this is fraught with additional costs.

The modern market offers a wide selection of units that operate on standard 220 volts. Whether the fan housing is wide or narrow, it must be durable and able to protect internal components from moisture that may seep into the housing. If there is an IP24 mark in the passport, the device is mounted half a meter from the shower or bathtub (at least). The IP25 rating has no such restrictions.

Regardless of how much the model you like costs, it should be designed for installation in combined rooms (bathroom/toilet). Such information is indicated in the passport.

Performance

The main task of the fan is to quickly update the atmosphere inside the selected room. The multiplicity of this indicator for the bathroom is 4-8. It is understood that during this period of time the device will completely replace the air in the room. For a small family, indicator 6 will be sufficient for a room of 15 m2. Multiplying the numbers you get 90 – the minimum performance indicator of the selected device.

Noise

Constant loud sounds can drive anyone crazy, especially neighbors. Based on the established rules, devices installed in an apartment should not emit noise levels exceeding 55 dB. If possible, this figure should be kept to a minimum.

Dimensions

The dimensions and geometry of the selected device must correspond to the existing ventilation shaft connector. Often we are talking about devices with a diameter of 100/125 mm. Also, during the selection process, you should pay attention to the installation method recommended by the manufacturer. The existing mounting holes must be placed against a solid building structure, otherwise the installation of a special frame will be required.

Types of bathroom fans

Which of the fans on the market would be best for decorating a bathroom? You should pay attention to their varieties.

Axial models

The devices are designed as a wheel in a cylindrical body. There are cantilever blades along the surface of the product. The structure is fixed on an axial electric motor. The operating principle is based on the rotation of the wheel, capturing air by the blades and moving it. Axial fans are installed in the shaft openings.

Advantages:

• high efficiency - 100 cubic meters are cleaned in 1 hour;
• ease of installation - into the wall surface;
• operate without an air vent system;
• suitable for low pressure communications;
• effective under variable load conditions;
• compact sizes.

Minuses:

• minimum pressure;
• risks of air circulation disruption during installation;
• work loudly - noise level from 30 to 50 dB.

Advice! To increase the aerodynamic characteristics of the device, install a manifold first.

Radial fans

The devices are made in the form of a spiral casing (hollow cylinder) with a blade wheel. The efficiency of the entire mechanism depends on the shape of the blades. Manufacturers produce several elements:

• curved forward in the direction of movement - high performance, but insufficient removal of mechanical impurities and gas;
• curved back - convenient speed adjustment and good efficiency;
• “paddle wheel” - a straight design that works under conditions of high pressure and dense impurities in the air.

Advice! Straight-bladed models have high noise and low efficiency.

Radial fan for bathroom

The principle of operation of the fan is based on the entry of air masses into the holes of the blades, directing it radially, compressing it and then pushing it through the spiral casing into the supercharger.

Advantages:

• saving up to 20% of electricity;
• avoiding power grid overload;
• processing 1 m3 of polluted air in 1 second;
• corrosion resistance;
• presence of a protection relay and speed controller;
• connection to a network with a voltage of 220-240 V;
• ease of installation and maintenance;
• minimum noise level;
• take up almost no space.

Minuses:

• The greatest efficiency is only in spacious rooms.

Centrifugal units

Powerful devices with low noise levels are installed on the ventilation flow path. The devices consist of a wheel with blades, channels with a round or rectangular cross-section, suction and discharge mechanisms. Air masses are sucked into the blades centrifugally and pushed out perpendicular to a new portion of air.

Important! For home communications, only channel models designed for rooms of 15 square meters are suitable.

Installation of centrifugal fans is hidden. They are fixed under the ceiling and masked with plasterboard overlays.

Advantages:

• reliability of rigid and semi-rigid air vents;
• installation in the center of communication or in front of the air intake;
• work in highly polluted areas;
• withstand constant temperature changes.

Minuses:

• low energy efficiency;
• risks of engine explosion due to voltage fluctuations;
• the need for additional installation of an anemostat.

Roof structures

Fans act as exhaust hoods. The design consists of a fan, vibration-insulating gaskets, an electric motor, and automatic adjustment devices in a single housing. The main unit is axial or radial with blades that suck in air from one or both sides. Installation of the ventilation structure is carried out simultaneously with roofing work and includes the installation of deflectors, pipes, and passage elements.

Advantages:

• regular supply of fresh air;
• maintaining normal humidity;
• removal of specific odors and moisture;
• preventing mold growth;
• eliminating sewer odors.

Minuses:

• the need for insulation in winter;
• complexity of installation work.

The best duct fans for the bathroom

Duct fans can be installed almost anywhere in the air duct. This means that ventilation lines for them can be laid more efficiently, going around any obstacles. They can also be radial and axial; in everyday life, mainly the second type of device is used.

6. A fan with a noise level of more than 40 dB will disturb your sleep and rest.
7. The most effective devices are those with automatic humidity control.
8. Axial models are designed for self-installation.

Video about tips for choosing a fan for the bathroom and toilet

Choosing a bathroom fan

The operating principle of such equipment can be radial or axial. The latter is based on a simpler and more understandable design, the cost of which is lower than radial analogues. However, it is not without its shortcomings. There is noise during operation. Radial structures are installed in large rooms, as they are more powerful. Among them there are also products intended for home use, the noise level of which is lower.

In order for the selected model to be highly efficient, it is necessary to correctly determine the performance indicator. It is assumed that the measured volume of the bathroom is multiplied by the figure given below (air exchange rate). Standard calculations:

1. "8". Suitable for families of five or more.
2. "7". Used for families consisting of 4-5 people.
3. "6". An excellent solution if the bathroom will be used by 1-2 people.

In this way, you will be able to independently calculate the optimal performance indicator of the device. Measurements are carried out in cubic meters/hour. Also in the store you can find duct structures that are mounted on an area allocated for the air duct. Preference is also given to ceiling and wall products that are equipped with decorative overlays. Their installation is carried out at the entrance to the ventilation. The functionality indicator will directly depend on the availability of auxiliary functions.

So, popular models can be equipped with:

1. Check valve.
2. Convenient display.
3. Humidity sensor.
4. Curtains.
5. Automatic on and off system.
6. Human presence sensor.
7. Sleep timer.

Separately, I would like to note a number of models from the best manufacturers that are equipped with backlighting.

Characteristics by type of design

Structurally, bathroom and toilet fans can be of several types. It is based on the use of various design solutions, which affect the characteristics declared by the manufacturers.

Tips for choosing an exhaust fan

Before purchasing a fan, you need to calculate everything in advance. If the manufacturer does not indicate the amount of air driven, then it is better not to buy such fans, otherwise such a fan may not cope with the functions you need. In addition to this parameter, it is worth paying attention to the noise level. The fan can make quite a loud noise that will irritate you. A good, quiet fan will produce around 24 dB. This fan will operate almost silently and will not distract you.

The fans are installed in the vent, then wiring and grounding are provided.

Main characteristics of the exhaust fan

1. Performance

This parameter shows the amount of air (measured in cubic meters) passed by the fan per hour.

2. Noise level
3. Safety

For bathrooms, the fan's degree of protection index must be no lower than ip44.

4. Power consumption
5. Exhaust Fan Dimensions

All axial exhaust fans are standardized and there are several basic sizes. To make the right choice, you need to know the size of the ventilation hole where the fan is supposed to be installed.

Exhaust fans vary in the diameter of their ducts. Standard sizes include: 105mm, 125mm and 160mm, and others are also available.

Types of fans

Forced exhaust for bathrooms and toilets can be made in a standard or automatic version. The first is a simple device with a fan fixed on an axis and an electric motor that starts working when the light is turned on and turns off when turned off. The power of this device is sufficient for ordinary short-term procedures, but it will be insufficient if there is a lot of steam and humidity is higher than the standard.

For such conditions, an automatic fan with a check valve is better suited. This is a more technologically advanced and complex technique, the design of which includes:

• timer for setting a specific switching time and operating duration;
• hydrostat, which controls the humidity level and turns on ventilation when it is exceeded;
• a check valve that will operate when turned off and block the channel from reverse flow.

Which option is better to use in the bathroom and toilet depends on the conditions of use. All that remains is to select a specific device with certain parameters.
