Frequently Asked Questions (FAQs)

1. What makes the stainless steel finish different from the white version?
The stainless steel finish offers a premium metallic appearance that resists fingerprints and coordinates beautifully with modern chrome, brushed steel, and nickel bathroom fittings for a cohesive designer look.

2. Will the stainless steel finish corrode in humid bathroom conditions?
The finish is specifically designed for bathroom environments with IP45 protection, resisting moisture and humidity. The durable metallic coating maintains its appearance with minimal maintenance in normal use.

3. Does the LED backlight colour differ between white and steel models?
The LED backlight typically provides a cool white illumination on both models, but the stainless steel surround reflects the light differently, creating a more metallic, premium appearance compared to the white plastic version.

4. Is this fan suitable for installation in steam rooms or wet rooms?
With IP45 rating, it's protected against water jets and suitable for bathroom zones, but for continuous high-steam environments like steam rooms, consult manufacturer specifications for suitability.

5. How do I clean the stainless steel faceplate without scratching it?
Use a soft, damp cloth with mild soap if needed, wiping gently in the direction of any grain. Avoid abrasive cleaners or scouring pads that could scratch the delicate metallic finish.
