Swing fan for supply and exhaust ventilation

Nowadays, the industry produces a large number of a wide variety of fans. Depending on their type, different purposes are distinguished.

One of the important functions that these window devices successfully handle is the ventilation of rooms. This problem is relevant in modern buildings, when often the ventilation system in insufficient volume provides air replacement.

It can be said that a modern device installed in the window leaves air in and out of the room.

Lightweight appliances are ideal for window mounting. Special insulating gaskets protect against noise. Installation of this design will not require significant financial investments, and will provide an influx of fresh air into the room. The ease of installation allows even without the involvement of specialists to complete the entire installation without any problems.

Window vent fans are used not only in private homes. They are successfully used in factories, shops, offices and other premises for working purposes.

The compact size makes it easy to mask it with curtains or blinds.

High service life (more than 10 years), a huge variety in power, design and other technical characteristics allow you to make a choice based on specific needs.

In most cases, window models are made of white or beige plastic.

Existing types of fans for windows

Initially, they are all divided into industrial and domestic. To install the object in the apartment window, of course, a lighter, albeit low-power device is required.

All these devices are divided into:

• exhaust. Most often applicable in the kitchen or toilet, as well as in other places of accumulation of unpleasant odors. A more efficient exhaust system is not always possible to install due to its design characteristics. It is then that the installation of a device of this type is advisable. It provides the exit of polluted air to the street. Fresh air is supplied either from adjacent rooms or from subsequently open windows;
• supply. They are most often used to ensure the influx of fresh air and cool the room. Against the background of expensive split systems or air conditioners, this option is very economical and affordable. However, when the street temperature is too high, the use of this method is not justified;
• supply and exhaust. It is also called reversible. This is the most versatile species, capable of providing both inflow and outflow of fresh air. The flow is switched by changing the direction of movement of the fan blades. The use of such a device is diverse: these are garages, and kitchens, and rooms, and many other rooms where intensive air exchange is necessary. The operation mode is signaled by a special indication located on the device body;
• for convenience, models for windows with an off timer have already appeared on sale.

Criteria for choosing a reversible window fan

When choosing a supply and exhaust mechanism for windows, it is important to pay attention to its following characteristics:

• work volume. Devices that make noise above 30 dB for use in a residential environment are not comfortable. However, it is important to remember that absolutely silent structures of this type simply do not exist;
• power. It is calculated based on the area of ​​the room;
• the presence of blinds (for window models, they almost always work in automatic mode). They are used when the device is completely turned off, preventing dust and dirt from entering the building. Sometimes the blinds can be replaced with a special cover, which additionally protects from moisture in the device;
• if the work is to be done in conditions of high humidity, then you should pay attention to waterproof models;
• for convenience, a special remote control is possible.

Pros and cons of using

When choosing your supply and exhaust window device, you need to understand all the advantages that it has:

• small sizes. Possibility of installation even in a small opening;
• affordable price category;
• It works both at a positive temperature and at a negative temperature (unlike, for example, from a split system that cannot be used in cold weather);
• easy installation. Subject to a number of conditions, even a layman can handle the installation. Yet for its operation, assembly of a duct network is not required. Even the presence of ventilation shafts in the building is not essential;
• the ability to control the speed and direction of rotation;
• low noise level;
• energy saving;
• high performance;
• ease of management. There are models with a remote control.

Since all window reversing models are equipped with anti-vibration gaskets, vibration does not extend to the window.

The disadvantages of this device include:

• when the window mechanism operates in winter, warm air is ejected from the room and forced supply of cold air. Thus, heat loss inside the building increases, and additional resources may be required to heat the room;
• despite the possibility of choosing a device with a low noise level, it is impossible to completely eliminate it.

Installation of a fan vent

1. To install a reversing device, first of all, the replacement of ordinary glass with a stronger material is required. These works are preparatory and are carried out prior to installation. In the prepared sheet, the area for the fan casing is marked and cut out, as well as the holes for attaching the device.
2. Prepared glass or cardboard is installed in the frame and fixed there securely.
3. The next step is the process of installing the fan.
4. This is followed by connecting the electrical cord and its output through a network loop, followed by connecting to an electrical outlet.

During installation, the following nuances should be considered:

• if the window into which the fan is planned to be installed is plastic, then it is more advisable to order the installation of the device during the window manufacturing process. Then it will immediately make a special window with a prepared hole. With self-installation, there is a risk of violation of the integrity and integrity of the window sash;
• fastening to ordinary glass is prohibited, since during the operation of the device it can crack and even break.

The right choice of a window supply and exhaust device for windows, as well as its competent installation will allow the device to work for a long time and without breakdowns, providing good ventilation in a given room.
