Vortice Ariett 100mm 4" Centrifugal Bathroom Extractor Fan with Timer | 11976

High-Performance 100mm Centrifugal Extractor Fan with Adjustable Timer

The Vortice Ariett 11976 is a powerful 100mm (4") centrifugal bathroom extractor fan with timer, designed to provide reliable extraction of moisture, humidity and unwanted odours from bathrooms, shower rooms, en-suites and WCs.

Unlike a standard axial fan, the Ariett uses a forward-curved centrifugal impeller, making it particularly suitable for installations where greater pressure performance is required. Its shallow exhaust sleeve also makes installation easier where the fan is positioned close to a 90° duct bend.

The fan features dual-speed operation, allowing the appropriate performance level to be selected for the installation. The integrated electronic run-on timer can be adjusted from 3 to 20 minutes, allowing ventilation to continue after activation to help clear residual humidity and odours.

Manufactured from durable, UV-resistant ABS plastic and incorporating a heat-protected ball-bearing motor rated for more than 30,000 hours of operation, the Vortice Ariett is designed for dependable long-term domestic ventilation.

Centrifugal Extraction Performance

The Ariett uses a centrifugal impeller rather than the conventional axial design found in many standard bathroom fans.

Its forward-curved blades are designed to provide effective air extraction while handling the additional resistance encountered in more demanding duct installations.

With airflow of up to 70m³/h, the fan provides effective extraction for controlling moisture, condensation and odours in suitable domestic rooms.

Dual-Speed Operation

The Vortice Ariett offers two selectable operating speeds, allowing extraction performance to be tailored to the requirements of the installation.

The fan is also compatible with suitable Vortice controllers, providing additional control where required.

Adjustable 3–20 Minute Timer

This T model incorporates an electronic run-on timer that automatically keeps the fan operating for a selected period after activation.

The timer can be adjusted between 3 and 20 minutes, with a default setting of approximately 3 minutes.

This continued extraction is particularly useful in bathrooms and shower rooms, helping remove residual moisture after bathing or showering and reducing the potential for condensation.

Installer-Friendly Shallow Exhaust Sleeve

A shallow exhaust sleeve provides greater installation flexibility, particularly where space behind the fan is restricted.

The design makes the Ariett suitable for installations where the ductwork incorporates a 90° bend close to the fan, providing additional versatility compared with some conventional extractor designs.

Long-Life Ball-Bearing Motor

The Ariett incorporates a shaded-pole, heat-protected ball-bearing motor designed for dependable long-term operation.

With a stated motor life of more than 30,000 hours, the fan provides a durable ventilation solution for regularly used bathrooms and other domestic wet rooms.

Durable ABS Construction

The outer casing is manufactured from robust ABS plastic that is both shock resistant and UV resistant.

This construction helps protect the fan while reducing material ageing and maintaining its appearance throughout its service life.

IPX4 & Class II Protection

The IPX4 rating provides protection against splashing water, making the fan suitable for appropriate bathroom and wet-room applications.

The fan is also Class II double insulated, meaning an earth connection is not required.

Installation should always be completed in accordance with the manufacturer's instructions and applicable electrical installation regulations.
