Although a surface-mounted extractor fan cannot be compared in many respects with a conventional cooker hood, there is one thing that is equally valid for both appliances. Surface extractors, like cooker hoods, can operate in two modes: exhaust to the outside or recirculation. In both cases, the vapors generated during cooking and frying are drawn in by the extractor, and grease particles and odors are safely removed. There are differences in the air flow: In the recirculation variant, the aspirated air passes through a sophisticated active carbon filter (cleaning and removal of odor molecules) and is returned to the room. In the extraction variant, it is discharged to the outside. Which variant is best for which kitchen depends on many factors – architectural features, for example, are decisive. A comparison of the advantages and disadvantages of the two systems shows which factors you need to take into account when deciding.
Why is it important to ventilate the room?
Ensuring adequate ventilation with outside air can help reduce the concentration of airborne contaminants, such as viruses, in enclosed spaces. … In general, the more people in an enclosed space, the greater the need to ventilate with outside air.
Why is ventilation important in a workspace?
Good ventilation in the workplace is very important for the productivity and health of the people who work there. This avoids the famous thermal stress produced by the excessive accumulation of heat in our body. It also avoids the transmission of disease-causing agents in the environment.
What is the best ventilation for a bathroom?
The best solution in the home to eliminate water vapors, gases and bad odors in humid areas such as kitchens and bathrooms is dual-flow ventilation, which is capable of preventing even fogged windows in closed bathrooms, while introducing filtered and renewed outside air …
Recirculation hood
At home, the ideal humidity level is between 40% and 60% relative humidity. Below these values, bacteria, viruses and respiratory diseases start to appear. Above this level, fungus, mold and allergic disorders are common among the inhabitants of the house.
In these spaces with excess humidity, the environment must be kept in depression* and this is achieved by letting air in through grilles or holes (located in the appropriate areas of the building) that will recirculate throughout the room and drag the excess humidity and temperature to the outside thanks to VMC’s extractor fans.
*The ventilation by depression renews the air by subtracting it with exhaust fans and letting in air from outside. Thus, a difference in atmospheric pressure is created which makes the outside air push the inside air to the outside through the VMC fans.
Here we leave you a guideline, although you should know that in addition to the regulations, it depends on the activities that are carried out in that space, the occupation of people and the square meters of surface.
What to consider when choosing an extractor fan for the bathroom?
Ideally, the flow rate should be ten times the air volume of the bathroom (easily calculated by multiplying width x height x length). That is to say, if our bathroom has 12 m3, we multiply it by ten and we obtain that our bathroom extractor fan should have an extraction flow of 120 m3/hour.
How to ventilate an enclosed space?
To this end, all rooms in the home should be aired daily and windows should be opened for at least 15 minutes when entering a room, especially if it has been previously used by other people.
How to improve the ventilation of a room?
Place a fan as close as possible to an open window, and pointing outward. This helps get rid of virus particles that may be in your home by blowing the air out. Even without an open window, fans can help improve air circulation.

What is ventilation at work?
Ventilation is the introduction of fresh air into a given space. It is a means of controlling heat and pollutants in the workplace atmosphere.
What should the ventilation in the workspace be like?
In difficult professional environments as well as in offices, ventilation at work can be ensured by the following actions: Minimize heat-generating and steam-producing processes. … In addition, if it is hot, a higher air velocity can facilitate cooling.
What is occupational ventilation?
Ventilation is a technique to control the work environment through the use of air flow, it consists in the renewal of air by natural or mechanical means in order to reduce the agitation of annoying odors, environmental conditions and the removal of the concentration of pollutants …
What is the best dead-end kitchen purifier?
Good ventilation in the workplace is very important for the productivity and health of the people who work. This avoids the famous thermal stress produced by the excessive accumulation of heat in our body. It also avoids the transmission of disease-causing agents in the environment. Ventilation is nothing more than air circulation, the entry and exit of air into and out of the workplace. When we renew the air we are evacuating all the agents harmful to health (heat, odors, fumes, smoke, dust, viruses, etc.) that may be affecting people, animals, machines or products in storage within the place. The amount of renewals will depend on the site and the activity that is being developed there. Many times this air renewal can be produced naturally (doors and windows), but other times industrial fans are needed to cause this effect, depending on the activity that develops in your workplace, we recommend that you consult a specialist or professional company in ventilation.
