Replacement covers for ventilation fans can be obtained either from dedicated replacement-parts retailers, such as eReplacementParts.com and Encompass Supply Chain Solutions, or directly from the manufacturer of a particular fan. An exact model or part number is required to locate the appropriate cover for the unit being serviced.
Replacement-parts retailers carry a wide range of ventilation fan covers for different brands; however, the scope of coverage varies greatly from one retailer to the next. For example, Encompass Supply Chain Solutions only sells parts for Panasonic ventilation fans. On the other hand, the selection at eReplacementParts.com is slightly broader, marketing brands such as Broan and NuTone. Additionally, due to the retail nature of these businesses, the availability of fan covers is affected considerably by the year the model was released, and whether or not it is still being manufactured.
If retailers do not carry a particular replacement ventilation fan cover, buyers can check for its availability directly with the manufacturer of the unit. Broan, for example, has a Parts Store section on its website that even allows customers to purchase replacement parts for a fan series it has discontinued. To further ease the process of finding the right cover when its part number cannot be found, the company provides a parts catalog with a complete list of model and part numbers.
