Bathroom Ventilator AWENTA WES125H, Ø125 mm, 175 m³/h, 18 W, 230 V, humidity sensor, timer, silver

The AWENTA WES125H bathroom ventilator is an inline extractor with a 125 mm duct diameter, designed to provide continuous and demand-controlled air extraction for bathrooms, toilets and small utility rooms. With a maximum airflow of 175 m³/h and a rated power consumption of 18 W at 230 V, this unit combines efficient ventilation performance with relatively low energy use. Built-in humidity sensing and an adjustable timer allow the fan to start automatically when humidity rises and to continue running for a set period after use, reducing condensation and lingering odors.

Advantages

The ventilator integrates a humidity sensor that activates extraction only when needed, improving indoor air quality while saving energy. Its compact inline design and 125 mm diameter make it compatible with standard ducting and allow flexible installation away from the room for quieter operation. The adjustable time delay ensures the space is ventilated sufficiently after occupancy without manual intervention.

Suitable for

• Bathrooms and showers with moderate moisture load
• Separate toilets and WC rooms
• Small utility rooms, laundry rooms and storage areas
• Ventilation runs where a quiet, inline extraction solution is preferred

Key specifications

• Duct diameter: 125 mm
• Maximum airflow: 175 m³/h
• Power consumption: 18 W
• Supply voltage: 230 V
• Built-in humidity sensor for automatic operation
• Adjustable timer / delay-off function
• Inline configuration for remote mounting and reduced noise

How to use

Install the AWENTA WES125H in-line with the ducting so the fan is connected securely to 125 mm ventilation pipework. Connect the electrical supply to a 230 V circuit according to local wiring regulations and the manufacturer’s wiring diagram. Set the humidity sensor threshold if adjustment is provided and choose the desired timer delay to determine how long the unit runs after humidity falls below the threshold. Once powered, the fan will operate automatically when indoor humidity rises above the set point and will turn off after the selected delay.

Usage recommendations

Position the fan in a location with sufficient airflow clearance and minimize long runs or multiple bends in the duct to preserve airflow efficiency. For best performance clean or inspect the fan and ductwork periodically to remove dust and obstructions, and ensure electrical connections are performed by a qualified electrician.
