⭐ Key Features

High-Capacity 255m³/h Airflow

With an airflow capacity of 255m³/h, this powerful 6-inch extractor fan is designed for spaces where higher-capacity ventilation is required.

It can help remove moist air, shower steam and unwanted odours from larger bathrooms, wet rooms, utility areas and other suitable high-humidity environments.

The effectiveness of any extractor fan can also depend on factors such as room size, duct length, the number of bends in the ducting and installation quality.

Built-In Humidity Sensor and Adjustable Timer

The integrated humidistat is designed to respond to increased moisture levels in the room, helping the fan operate when humidity rises.

The adjustable 1–30 minute run-on timer allows the fan to continue operating after activation, helping to remove remaining moist air and condensation.

This combination of humidity sensing and timed operation makes the fan particularly suitable for bathrooms and wet rooms where steam levels can increase quickly during showers.

Quiet 31dB Operation

Despite its high extraction capacity, the fan operates at approximately 31dB, helping to provide effective ventilation with relatively low operating noise.

This makes it a practical choice for bathrooms and household spaces where quieter operation is preferred without sacrificing airflow capacity.

Actual perceived noise can vary depending on the installation, surrounding environment and ducting configuration.

Energy-Efficient 21W Motor

The extractor fan has a power consumption of 21W, combining high-capacity airflow with relatively low energy use.

Its copper-coil motor is designed to provide reliable operation and consistent ventilation performance.

IPX4 Splash Protection

With an IPX4 protection rating, the fan provides splash protection suitable for appropriate bathroom and high-humidity installations.

Always ensure that the installation location and electrical connection comply with applicable UK electrical and bathroom safety requirements.

Modern Matte Black Design

The stylish matte black front fascia makes this extractor fan an excellent choice for contemporary bathroom interiors.

Its modern finish works particularly well alongside:

• Matte black taps and shower fittings

• Black bathroom accessories

• Modern towel radiators

• Industrial-style interiors

• Contemporary and minimalist bathrooms

The black design allows the ventilation system to become part of the overall bathroom aesthetic rather than simply being a functional white fitting.

Frequently Asked Questions

What Size Ducting Does This Extractor Fan Require?

This extractor fan is designed for 150mm (6-inch) round ducting.

Before installation, check that your existing ducting and wall opening are compatible with the dimensions and installation requirements of the fan.

A 150mm extractor fan is generally chosen where higher extraction capacity is required compared with smaller bathroom fan sizes.

Is 255m³/h Powerful Enough for a Large Bathroom or Wet Room?

An airflow capacity of 255m³/h provides high-capacity extraction for a domestic bathroom fan and can be suitable for larger bathrooms, wet rooms and spaces with higher levels of steam.

However, actual ventilation performance can depend on several factors, including:

• Room size

• Duct length

• Number of bends in the ducting

• External vent design

• Installation quality

For the best performance, the ducting should be installed correctly and kept as efficient as possible.

Does the Fan Turn On Automatically When Humidity Increases?

Yes. The WW-150QTH features a built-in humidistat designed to respond to increased moisture levels in the room.

This can be particularly useful in bathrooms where humidity rises quickly during showers or baths.

The exact operation and settings should be checked against the product installation instructions.

How Long Does the Timer Run?

The fan includes an adjustable 1–30 minute timer.

The run-on timer allows the fan to continue operating after activation, helping to remove remaining moist air after a shower or bath.

The appropriate timer setting can depend on the size of the room and the amount of humidity produced.

Is 31dB Quiet for an Extractor Fan?

A rated noise level of 31dB is designed to provide relatively quiet operation while maintaining a high airflow capacity of 255m³/h.

Actual noise levels experienced in the room may vary depending on installation conditions, ducting and the surrounding environment.

What Is an IPX4 Rating?

An IPX4 rating indicates protection against water splashes.

This makes the fan suitable for appropriate bathroom and high-humidity environments when installed in accordance with applicable electrical safety and bathroom installation requirements.

Always ensure the installation location is suitable for the product and complies with relevant regulations.

What Does the Humidity Sensor Do?

The built-in humidity sensor, also known as a humidistat, is designed to detect increased moisture levels in the air.

When humidity rises, the humidistat can activate the ventilation system to help remove moist air from the room.

This can be useful in bathrooms and wet rooms where shower steam and condensation are common.

Is This Extractor Fan Suitable for a Wet Room?

With its 255m³/h airflow capacity, built-in humidistat and IPX4 splash protection, this fan is designed for high-humidity environments.

However, the suitability of any electrical product for a particular wet-room location depends on the installation position and applicable bathroom electrical zones.

Always check the installation instructions and use a qualified electrician where required.

Why Choose a 150mm Extractor Fan?

A 150mm (6-inch) extractor fan uses a larger duct diameter than smaller bathroom fans and is often selected where higher extraction capacity is required.

When choosing the right extractor fan, consider:

• Room size

• Airflow capacity

• Noise level

• Duct diameter

• Duct length and bends

• Humidity control

• Timer functions

• Installation location

• IP protection rating

Choosing the correct fan is important, particularly in bathrooms and wet rooms where regular moisture can contribute to condensation.

A Practical Choice for High-Humidity Bathrooms

Bathrooms with frequent showers, larger family use or wet-room layouts can produce significant amounts of moisture.

A high-capacity 150mm extractor fan with a humidity sensor and timer can help provide effective ventilation by responding to increased moisture and continuing to extract humid air after use.

With 255m³/h airflow, quiet 31dB operation, a 21W motor, IPX4 splash protection, an adjustable timer and a modern matte black finish, the WW-150QTH combines practical ventilation features with a contemporary bathroom design.
