Comparison Blauberg VENTO Expert A50-1 S Pro vs Blauberg VENTO Expert A50-1 Pro

The presence of an EC fan(fans) in the design of the air handling unit.

This term refers to fans with synchronous brushless motors, also known as EC motors. Such motors are more advanced than traditional asynchronous ones: in particular, they provide very uniform rotation, allow precise control of speed, have high efficiency, and generate almost no heat (which is extremely important in the presence of a cooler, see "Features"), and also efficiently operate over a wide temperature range. In addition, the noise level of such motors is noticeably lower, and the service life is longer. The main disadvantage of EC fans is the traditionally high price.

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.
