With its own motor

The kitchen has its own duct for the kitchen exhaust fan.
The cooker hood has its own fan motor that blows the fumes out through the exhaust duct for the exhaust fan. Air is only removed through the cooker hood and the ventilation of the apartment is not controlled from the hood. A hood with own motor is the most common and often the most effective solution for removing fumes.

Almost all kitchen hood models are available with own motor. 

NOTE!
For the kitchen exhaust to work as intended, the supply of replacement air must be sufficient (the same amount of air must come in as goes out), and the duct must not cause excessive resistance to the airflow. Inadequate replacement air as well as duct resistance also increase the noise level of the fan.

With its own motor + active carbon filter

The range hood has its own fan motor, which blows the carts back into the room through the active carbon filter in the range hood. The ventilation of the apartment is not controlled by the range hood.

In this case, a motorized range hood is used, for which an active carbon filter is ordered as an accessory. The air circulates with the help of the hood motor through the fan and activated carbon filter, returning back to the room cleaned.

An active carbon filter is available as an accessory for almost all motorized range hoods.

NOTE!
A range hood equipped with active carbon does not need separate replacement air, because it circulates the air purified by active carbon filters back into the room. In order to function as planned, the filter, depending on the model, must either be washed or replaced at regular intervals.

The active carbon filter always forms a resistance to air movement, so the suction power is lower and, accordingly, the sound level is higher than in a similar model without a filter.

Control of the extractor fan

X1 - extractor fan with kitchen exhaust

This is usually a detached house or town house, where the kitchen fume extraction is done through its own extractor fan.

The control device (cooker hood) does not have its own motor but has built-in control for the extractor, which is located at the end of the exhaust duct (usually on the roof of the house). Air is only removed through the kitchen hood, and the duct is only for one apartment.

With Lapetek's X models, both traditional AC motors and energy-efficient EC motors can be controlled. The possible ventilation or LTO machine for basic ventilation in the building is not controlled from the kitchen control device (cooker hood), and the extractor hood should not be connected to the same duct as the ventilation or LTO machines.

NOTE!
For the kitchen exhaust to work as intended, the supply of replacement air must be sufficient (the same amount of air must come in as goes out), and the duct must not cause excessive resistance to the airflow. Replacement air can be provided through fresh air vents or the automation of the LTO machine. Inadequate replacement air as well as duct resistance also increase the noise level of the fan.

The suction power is determined by the selected extractor (its power), the supply of replacement air, and the resistance caused by the exhaust duct to the movement of air.

X2 - extractor fan with exhaust for kitchen and wet areas

This is usually a detached house or town house, where both kitchen fume extraction and basic ventilation occur through the same extractor fan.

The control device (cooker hood) does not have its own motor but has control for the extractor. The extractor is located at the end of the exhaust duct (usually on the roof of the house). In addition to the kitchen hood, air is also removed through the exhaust vents in other rooms (bathroom, toilet, wardrobe). The extractor removes air only from one apartment. Ventilation in other rooms can be enhanced by a function that closes the kitchen shutter and simultaneously sets the extractor to full power. In this case, the suction is primarily directed to, for example, damp rooms.

With Lapetek's X-models, both traditional AC motors and energy-efficient EC motors can be controlled.

The possible ventilation or LTO machine for basic ventilation in the building is not controlled from the kitchen control device, and the cooker hood should not be connected to the same duct as the ventilation or LTO machines.

NOTE!
For the kitchen hood to function as intended, the supply of replacement air must be sufficient (the same amount of air must come in as goes out), and the duct must not cause excessive resistance to the airflow. Inadequate replacement air as well as duct resistance also increase the noise level of the fan. Replacement air can be provided through fresh air vents or the automation of the LTO machine.

The suction power is determined by the selected extractor fan (its power), the supply of replacement air, and the resistance caused by the exhaust duct to the movement of air.

X3 - the control unit only has a shutter

It is usually an apartment building where all ventilation occurs either by gravity or through a shared extractor fan.

In the control unit (hood), there is no separate motor; instead, it only opens and closes the shutter located within the control unit. The shutter is usually also timed, so it cannot be left open. There is no power supply to the extractor fan through the control unit (hood).

The suction power is determined by the selected extractor fan or natural ventilation. The building management determines the efficiency of air removal. It can either remain constant or be enhanced during specific times (e.g., 7-9 and 15-18).
