Hi there, we're sorry to hear you're unhappy with the product, but we really appreciate you letting us know and this is certainly not a known issue with this fan, as far as we are aware. Although there's always a tradeoff between noise and airflow, a rattle can sometimes indicate an installation issue. Even though it sounds like you're confident that you've identified the source of the sound, we are still available to help troubleshoot to rule out any other possibilities. Our email is service@universalfans.com.au, please get in touch if you think we can assist.
Excellent service! I installed an exhaust fan for my customer and it vibrated badly. I was promptly sent a replacement after some intelligent questions were asked
Efficient,professional and great personal treatment from Amanda. Fan arrived as promised/planned and very pleased. I will definately use this company again.
