Manrose Showerfan Kit 4″/100mm

The Manrose Showerfan Kit 100mm (4″) offers a complete ventilation solution specifically designed for use in bathrooms, shower rooms, and en-suites where ceiling-mounted fans are not suitable or desired. This in-line axial fan system is installed in the loft or ceiling void and works in tandem with an integrated LED Showerlite, providing both light and powerful air extraction directly over the shower or bath area.

Frequently Asked Questions (FAQs)

Q: Can I install this fan directly in the ceiling?
A: The fan motor itself is not mounted in the ceiling but in the ceiling void or loft. The ceiling houses the grille and LED Showerlite, while the fan extracts through connected ducting.

Q: Is the light waterproof?
A: Yes, the included LED Showerlite is IP-rated and suitable for installation directly above the shower (Zone 1), when connected to an RCD-protected circuit.

Q: Can I operate the light and fan independently?
A: The standard configuration runs the fan in conjunction with the light or room switch. To operate independently, additional wiring or control units may be required by a qualified electrician.

Q: Is the timer pre-set?
A: The overrun timer is adjustable from 1 to 30 minutes. It is typically configured during installation using a small dial on the fan housing.

Q: Can the ducting be extended?
A: Yes, although for optimal performance, keeping the ducting length under 3 metres and minimising bends is recommended.
