Extractor Fans

Extractor Fans

Shop extractor fans at RS Electrical Supplies. Mechanical ventilation is a Building Regulations requirement in bathrooms, en-suites, shower rooms, and kitchens, helping to remove moisture-laden air to reduce moisture, condensation, damp, and mould. We stock extractor fans from Blauberg UK, a specialist ventilation manufacturer known for quiet, energy-efficient fans suited to domestic and light commercial installations.

Extractor Fan Types Available

• Axial bathroom extractor fans — wall or ceiling-mounted fans for direct extraction through an external wall or short duct run; the standard choice for most domestic bathrooms and shower rooms
• Inline extractor fans — duct-mounted fans installed within the duct run rather than at the point of extraction; suitable for longer duct runs, multiple room extraction, and loft installations where a quieter result is required at the grille
• Centrifugal extractor fans — higher static pressure fans for longer or more complex duct runs where axial fans would be insufficient

Key Considerations When Choosing an Extractor Fan

• Extract rate — Building Regulations Part F requires a minimum of 15 litres/second (54m³/hr) for bathrooms and 30 litres/second (108m³/hr) for kitchens; always check the fan's rated extract rate against the room volume
• Duct diameter — most domestic fans use 100mm (4") or 125mm (5") duct; match the fan to your existing duct size
• Timer or humidity control — overrun timers keep the fan running after the light is switched off; humidity sensors activate the fan automatically when moisture levels rise
• Noise level (sone/dBA) — lower sone ratings indicate quieter operation; important for en-suites and bedrooms
• IP rating — IP44 minimum for bathroom Zone 1 and Zone 2 installations

Installation of extractor fans must comply with Building Regulations Part F (ventilation) and BS 7671 wiring regulations. Order today with fast UK delivery from RS Electrical Supplies.
