Comparison Climtec RD-100 Standart vs Climtec RD-100 Baza

The diameter of the holes intended for connecting air ducts to the ventilation unit. The more performant the air ventilation unit, the more air the ducts must pass and the larger, usually, the mounting holes. For wall-mounted models (see above), this parameter determines the size of the channel that must be drilled into the wall to accommodate the unit.

The number of speeds at which the fans of the air ventilation unit can operate.

The presence of several speeds allows you to choose the actual performance of the installation, adjusting it to the specifics of the current situation: for example, in a production room, you can reduce the ventilation intensity during the night shift, where there are fewer people than in the daytime. And the more speeds provided in the device (with the same performance range) — the more choice the user has, the easier it is to find the mode that best suits current needs.

Note that if the minimum and maximum of the air flow are indicated in the specs, but the number of speeds is not given, this does not necessarily mean smooth adjustment. On the contrary, most often such models are regulated traditionally, in steps, but for some reason, the manufacturer decided not to specify the number of speeds in the characteristics.
