It operates on two selectable speeds — 400 m³/​h and 290 m³/​h — offering flexibility for different ventilation requirements.

Powered by a totally enclosed motor with long-life ball bearings, thermally protected windings, and quiet, maintenance-free operation. The swing-out impeller and motor unit allows for easy cleaning and servicing. The SVR 125 B is an ideal solution for compact and noise-sensitive ventilation applications.
