Types of fans for bathroom and toilet

The functionality of ventilation devices is quite important, so you ne to understand how to choose a hood for a bathroom or toilet. Today, all exhaust fans can be divid into two types.

The standard exhaust system for the toilet and bathroom is a conventional axial system equipp with a check valve, which is design to block the flow of exhaust air into the room.

This system is turn on and off architect data a light switch, which is quite convenient. However, when large volumes of steam are generat during the bath, this system is ineffective.

An automatic hood is a more advanc, but also expensive device. Such devices are equipp with special timers that are set for a certain period of time, and more functional devices are equipp with a hydrostat that determines the level of humidity in the room.

Having figur out the basic parameters of the device, all that depending on the intent there are 3 types of requests: is to choose a suitable system, which can be install independently without any problems. In this case, fastening is carri out with standard screws or glue.

Extractor hood in the bathroom

Construction manuals clearly indicate the standards that must be follow for effective ventilation of sanitary premises with high humidity.

The system must provide a fresh air flow for italy numbers bathroom or toilet at a rate of 25 cubic meters/hour, and for a combin unit twice as high – 50 cubic meters/hour. These standards are minimum.

Sometimes experts recommend removing air from the bathroom at a rate of about 150 cubic meters per hour.

Depending on the characteristics of air exchange, a distinction is made between natural and forc ventilation. In the first case, the exchange occurs due to the difference in air pressure outside and inside the room.

Air flows penetrate through windows, doors, special ventilators, etc. It is worth noting right away that due to the peculiarities of the bathroom design, the use of natural ventilation does not always allow you to achieve the desir effect.

To install ductless ventilation in the bathroom, it is necessary to make an opening that will connect the house ventilation duct with the bathroom.

When forc or artificially ventilating a room, special fans are us that provide sufficient intensity of air exchange.

Most often, a fan helps move air from the room to the street, while fresh air masses enter the bathroom from living quarters. Sometimes a small fan is plac in the toilet even with good natural ventilation to spe up the purification of air from unpleasant odors.

If it is not possible to organize sufficiently intensive air exchange naturally, forc ventilation is mandatory.

Types and functions of bathroom ventilation

Before choosing one or another air exchange system, it is necessary to familiarize yourself with the types and operating principles of such systems. Bathroom exhaust can be organiz by natural and forc methods.

• Natural extraction.

This type of hood operates due to the action of natural factors, such as the difference in pressure and air temperature inside and outside the room.

The exhaust air is remov through a ventilation duct running in the wall of the house. An open window or door through which fresh air enters is sufficient for air exchange.

Very often, especially in older apartment buildings, ventilation ducts are clogg or block due to the destruction of ventilation caps on the roof of the building. In such a case, natural exhaust in the bathrooms does not work.

Natural ventilation systems are inexpensive, easy to install and maintain, and do not require energy supply.

Natural exhaust in the bathroom and toilet is a simple and economical solution to the ventilation problem if there is good draft. At the same time, its disadvantages cannot be ignor:

1. unstable operation in hot weather, when the requir temperature difference is absent;
2. high sensitivity to clogging of ventilation ducts.

Checking ventilation

You can check the operation of the hood in the bathroom and toilet in two simple ways without using special equipment – using a candle or a sheet of paper.

A burning candle is brought to the ventilation duct – when the ventilation is working, the flame is deflect, indicating the direction of the air flow. In the absence of draft, the flame remains vertical.

To check the correct operation of the ventilation system, you can use the advice of experts. To do this, you will ne a regular sheet of paper, which is appli to the ventilation grille in the bathroom or toilet and if it is held on it by the air flow, then everything is fine with the hood.

In turn, if the paper falls on the floor, then you ne to think about installing an exhaust fan.

It should be not that even a normally functioning system does not always cope with its responsibilities, since it operates due to the difference in temperatures inside the apartment and outside.

Very often in the summer, when it is very hot outside, the natural ventilation system becomes completely useless and does not remove unpleasant odors from the toilet.

Poor ventilation may also be caus by insufficient fresh air flow. This problem is typical for old buildings after installing plastic windows. To solve it, you should install windows with ventilators.
