Wall box at a glance

  • The dimensions of the wall box and the exhaust air system must always match. There are standardized systems for this. There are systems with Wall box 100 mm, Wall box 125 mm and Wall box 150 gold wire.
  • A wall box opens automatically when the air pressure in the system increases and closes again when there is no air flow. The regulation is done by backflow flaps, which work either mechanically, electrically or via a magnetic lock.
  • Since a wall box comes into contact with the weather on the outside, it must be very robust and, above all, weatherproof. Stainless steel or plastic are very popular for this.

Bad smells don't have to be

Anyone who operates an extractor hood in their kitchen is given the choice between exhaust air and circulating air. With the exhaust air system, the sucked in air is directed outside via a chimney or duct, with the recirculating air only the air is cleaned and returned to the room. The most effective solution is to transport the used air outside through a wall duct. This not only removes odors, but also filters fat and suspended particles from the air and directs them outside. Our Wall box comparison from Test-Vergleiche.com would like to introduce you to the various wall boxes.

What is a wall box needed for?

While the smell of fresh cake is perceived as pleasant, the smell of sauerkraut or cabbage takes getting used to. While a hungry family literally inhales the smell of a hearty meal, it doesn't let itself be stopped from smelling (stinking) further when you are already full. Not everyone likes permanent kitchen steam in their home. Opening the window is an option, but with the currently popular “American kitchens” or kitchens open to the living room, that's not enough. An extractor is needed, but in very few cases an extractor hood can be connected directly to a chimney, with one island hood that is even completely out of the question. It would be possible to use the air circulation system by using carbon filters to clean the air, but this is for example one Flachschirmhaube also not possible. The solution: an extractor hood whose exhaust air has to be led outside through ducts. You need one for this extractor Wall box.

Wall box note:

The wall box as a wall duct for exhaust air must not be confused with a Wall box for belt winder or shutters. These are also known as wall boxes, but in this case they are only one type wall safe for built-in parts.

Wall box

Wall box note:

If an exhaust air system is operated via a wall box in small kitchens or closed rooms, it can lead to negative pressure in the room. This is particularly dangerous when a fireplace such as a stove or a gas boiler is in operation. To prevent the formation of toxic gases, a window contact switch can prevent the build-up of negative pressure.

How does a wall box work?

The mechanics in the wall box work automatically, be it through air pressure or electrically opening backflow flaps. In the first variant, the air drawn in from the filter hood presses the backflow flaps open and the air drawn in can flow into the open. At the Wall box electric operated, the flaps open immediately when the extractor hood is switched on. The connection is offered for exhaust air pipes or for flat ducts.

  • The exhaust wall box

These are the trendy ones Wall box bestseller for most of the common air filter covers. Last but not least is one of those Wall box cheaper than the electric variants. The drive is very simple. The air flow pushes the flaps open, which fall back when the air flow stops. If magnets are still attached to the backflow flap, it closes very reliably, but requires a higher air flow to open.

  • The electric wall box

Since the mechanically controlled wall box has poor thermal insulation, this can be a problem in low-energy houses. In the electric version, the flap is moved by a small motor. This works according to two different principles, control via a sensor or with coupling to the air filter cover.

Wall box note:

Before you get one of those Buy wall box, you should observe the manufacturer's information on the required air output, which is given in m³ / h.

  • The wall box with thermobox

This is a built-in heat retention system. It consists of backflow flap pairs arranged one behind the other, which usually have a magnetic lock. This mostly 150 wall box air conditioner, insulates very well and offers separate air chambers. In this way, heat losses are effectively rented out and they are mainly used in well-insulated, suitable for energy-efficient or passive houses.

Our wall box purchase advice

There is one for each type of wall penetration Wall box cheap. No matter if it is a Wall box 150 stainless steel is or a 125 with backflow flap wall boxNot all wall boxes are the same. Therefore, before you buy a wall box, you should familiarize yourself with the most important purchase criteria.

  • The wall thickness

All wall boxes are available with a telescopic intermediate pipe. Our Wall box purchase recommendation therefore advises to determine the wall thickness and to choose a wall box whose installation depth is not too tight.

  • The diameter

The diameter depends on which exhaust system fits your air filter hood. At a 150 extractor hood a wall box with a diameter of 150 mm is also required. There are spacers in stores, but they should only be used in extreme emergencies because they create inefficient turbulence and slow down the flow of exhaust air.

Wall box note:

A large diameter does not necessarily convey more stale air to the outside. If the diameter is reduced, the pressure is increased, and if it is enlarged, the pressure is reduced. However, the volume flow remains the same.

  • The core drilling

The diameter of the wall box is not the same as the diameter of the required hole through the wall. Therefore, the manufacturers always specify the diameter of the required core drilling. This information should be followed exactly so that there are no thermal bridges later.

  • The material

Wall boxes are mainly made of stainless steel, stainless steel with a plastic intermediate pipe or made entirely of plastic. Our Wall box recommendation tends towards stainless steel boxes, because stainless steel is very robust and insusceptible to the weather. This is also plastic, but the outside of the UV radiation can turn yellow over time.

  • The design

The type of construction depends on how your facade is made. With a well-insulated facade, the wall box must not become a weak point. If you are unsure, you should get in touch with a kitchen fitter who is familiar with the different exhaust air variants of the extractor hoods.

  • The type of closure

You should by no means underestimate the locking of your wall box. If you have a Wall box with backflow flap If there is a strong wind, for example, air from the outside can penetrate and the mechanical parts cause noise. With a magnetic lock, the risk is much lower because the backflow flaps then close quite tightly. Please note, however, that your extractor hood is a bit more powerful because the attraction force of the magnet has to be overcome first.

  • The outside

The outer element is provided either with a grille or with slats. These cover the exhaust pipe and the drilled opening. Small water deflectors at the lower end are particularly practical. As with a window sill, they prevent the rain from running down the wall and producing unsightly noses in the case of an exhaust air system.

An extractor works most effectively when its exhaust air is via a round or Flat duct wall box is promoted outside.
