The Awenta WO series is an industrial and commercial axial wall fan designed for ventilating large spaces such as garages, warehouses, workshops and hospitality venues — wherever serious air exchange is needed.
The WO features 3 speed settings, adjustable depending on the wiring configuration. The fan can be installed in ductwork or directly into a wall. Available in three sizes: 200, 250 and 315 mm.
The official manufacturer's data sheet contains all the key technical specifications — performance, pressure and noise levels, dimensions, and installation information. A handy reference for electricians, architects, or anyone who needs precise technical details for installation.

The WO series is purpose-built for spaces that need serious air exchange. The largest 315 mm version delivers up to 1,025 m³/h on its highest setting.
That's enough for a complete air change in a 50–100 m² garage or warehouse.
The WO motor has three speed settings. Depending on the wiring configuration, you can select low (quiet), medium, or high (intensive) speed.
This allows the fan's performance to be matched to actual requirements.
The WO is available in much larger sizes than domestic fans.
The 200 mm suits smaller workshops, the 250 mm medium-sized warehouses, and the 315 mm is ideal for large industrial spaces.
The WO is flexibly installable: it can be fitted into ventilation ductwork or mounted directly into a wall as an extractor fan.
Metal guard grilles on both sides protect the blades.
The WO uses sleeve bearings, which means it must ONLY be mounted on a vertical wall.
Ceiling or horizontal installation is NOT recommended — sleeve bearings cannot handle this type of load.
The WO200 is ideal for spaces up to 20–40 m² (max 365 m³/h). The WO250 is recommended for 40–60 m² (max 465 m³/h). The WO315 is best for rooms over 60–100 m² (max 1,025 m³/h).
The motor offers three different wiring options. Depending on the connection, it operates on speed 1 (quietest), speed 2 (medium) or speed 3 (most powerful). Changing speed requires modifying the electrical wiring.
Yes! The WO was designed precisely for this purpose. IP44 protection ensures it operates reliably in dusty, damp environments.
We do NOT recommend it. The WO uses sleeve bearings, which will fail quickly in a horizontal position. It is only suitable for vertical wall mounting.
Noise levels depend on the size and speed setting. The WO200 runs at 33–40 dB, the WO250 at 38–40 dB, and the WO315 at 36–46 dB depending on the selected speed.
