1. Introduction
The Vent Axia Silhouette 100T is a high-performance bathroom and toilet extractor fan designed for efficient ventilation. Its ultra-slim 17mm profile allows for discreet integration with wall surfaces, providing an unobtrusive installation. This model features an integral adjustable electronic overrun timer, allowing the fan to continue operating for a set period after the light switch is turned off, ensuring effective moisture and odor removal.
The fan is suitable for ceiling or panel mounting and can be connected to appropriate ducting for external exhaust. Optional fixing kits are available for wall and window installations.
2. Safety Information
Please read all safety instructions carefully before installation or operation. Failure to comply with these instructions may result in electric shock, fire, or personal injury.
- Electrical Installation: All electrical work must be carried out by a qualified and competent electrician in accordance with current wiring regulations (e.g., IET Wiring Regulations BS 7671 in the UK).
- Power Disconnection: Always ensure the main power supply to the fan is disconnected at the consumer unit/fuse box before commencing any installation, maintenance, or cleaning.
- Water Proximity: This fan is designed for bathroom use but must be installed in a zone appropriate for electrical appliances, away from direct water spray.
- Ventilation: Ensure adequate ventilation is provided for the room when the fan is in operation to prevent back-draughting of fumes from open-flued appliances.
- Damage: Do not operate the fan if any part is damaged. Contact a qualified technician for repair.

Image: Vent Axia Silhouette 100T Bathroom Extractor Fan. This image shows the Vent Axia Silhouette 100T Bathroom Extractor Fan. It is a white, square-shaped fan with a circular grille covering the fan blades. The Vent-Axia logo is visible in blue text at the bottom right of the fan's front panel. A small cylindrical protrusion is visible on the left side, indicating the duct connection.
- Preparation: Ensure the power supply is disconnected. Determine the mounting location (ceiling, wall, panel, or window) and ensure there is sufficient space for the fan unit and ducting.
- Mounting Hole: Cut an appropriate size hole for the fan body and duct connection. Refer to the fan's dimensions for precise measurements.
- Wiring: Connect the electrical wiring according to the wiring diagram provided in the fan's internal instructions. This model features an integral earth. Ensure Live (L), Switched Live (SL), and Neutral (N) connections are correctly made. The Switched Live connection activates the fan and timer.
- Ducting: Connect suitable ducting (e.g., 100mm diameter) from the fan's spigot to the external exhaust point. Ensure ducting is as straight and short as possible to maximize airflow.
- Secure Fan: Secure the fan unit firmly in place using appropriate fixings for your mounting surface. Ensure the fan is level and stable.
- Timer Adjustment: Before replacing the front fascia, adjust the electronic overrun timer to the desired setting (5-30 minutes) using the small adjustment screw/dial located on the fan unit.
- Fascia Installation: Carefully attach the ultra-low profile front fascia to the fan unit. Ensure it clicks securely into place.
- Power Restoration: Once installation is complete and all connections are secure, restore power to the fan at the consumer unit/fuse box.
6. Operating Instructions
The Vent Axia Silhouette 100T operates automatically when connected to a switched live supply, typically linked to a room's lighting circuit.
- Activation: The fan will activate when the connected light switch (or other switched live source) is turned on. The indication light on the fan will illuminate.
- Timer Function: When the light switch is turned off, the fan will continue to run for the duration set on its adjustable electronic overrun timer (5-30 minutes). This ensures continued ventilation after the room is vacated.
- Deactivation: After the set timer period expires, the fan will automatically switch off.
7. Maintenance
Regular cleaning and maintenance will ensure optimal performance and longevity of your extractor fan.
- Power Disconnection: Always disconnect the power supply to the fan before performing any maintenance.
- Exterior Cleaning: Wipe the exterior of the fan and grille with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals.
- Internal Cleaning: Carefully remove the front fascia. Gently wipe the fan blades and internal surfaces with a soft, dry cloth or a slightly damp cloth. Avoid getting water into electrical components.
- Reassembly: Once clean and dry, reattach the front fascia securely.
- Frequency: Clean the fan every 3-6 months, or more frequently in dusty or high-humidity environments.
