Difference between cooker hoods and recirculation hoods

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.

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.

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.
