Remote control

The presence of a remote control in the delivery set of the air ventilation unit.

This configuration is provided in most decentralized models (see "System"). However, it is often found in centralized ones. The possibility of a remote control provides additional convenience for the user — you do not need to approach the unit every time. In addition, many control functions can be transferred to the remote control, making the installation itself more compact (this is true for the mentioned decentralized equipment, which has a rather small size).

Note that the remote control can be both portable and wall-mounted, designed to be permanently in one place (like a wall light switch).

Minimum wall thickness

The minimum wall thickness on which the air ventilation unit can be hung with the possibility of wall mounting.

This parameter is indicated for models mounted directly into a hole in the wall — see "Mounting" for details. The installation length (the length of the pipe between the trims) can usually be adjusted to suit specific wall thicknesses. However, if this thickness is too small, then even an extremely shortened pipe will stick out of it, preventing the entire structure from being securely fixed. This is the reason for this limitation. Theoretically, the situation can be corrected — for example, by building up a wall at the installation site — however, in fact, such options are unlikely to be considered seriously. Nevertheless, in most models, this limitation does not exceed 300 mm, and it is very rarely necessary to install ventilation units on thinner walls.
