Ventline Accessories and Parts - BVD0217-00

  • RV Vents and Fans
  • Roof Vent
  • Fan Blade
  • Ventline
  • Ventadome

Replaces a lost or damaged fan blade on the 12-volt fan in your Ventline Vanair RV roof vent for motor homes and enclosed trailers.


  • Replaces a fan blade on Ventline Vanair RV roof vent for motor homes and enclosed trailers
  • Works with Ventline Vanair roof vent model VP-543 or VP542
  • Made in the USA

This fan blade won't fit older, obsolete motors. If your Ventline roof vent has an older motor, it will have to be replaced along with the fan blade. To determine whether you have an old or new motor, measure the length of the motor from end to end (excluding shafts and mounting hardware, measuring just the case.) If the motor measures 2", it is an older motor and should be replaced with the fan blade. A new motor measures 1-1/2" in length.

Replacement Fan Blade for Ventline Vanair Trailer Roof Vent - BVD0217-00

Average Customer Rating:  4.8 out of 5 stars   (53 Customer Reviews)

Replaces a lost or damaged fan blade on the 12-volt fan in your Ventline Vanair RV roof vent for motor homes and enclosed trailers.


Great replacement bath fan, easy instal lation!


The old part got hung up on a loose piece of weather stripping. The friction melted the mount to the motor shaft. Since etrailer had the fan I was able to get the fan delivered to my house for less than $20. The fan is under warrantee and I could get it fixed for free...……...except I'd have to bring it in to the dealer. That trip takes hours and more than $100 in fuel. This is so much better and only takes 30 minutes to drag tools/ladder out fix it and put everything away.

Still working great. I think we loggeg about 119 nights in the trailer last year. At least half with this fan removing moisture and other bathroom gasses.

Quick delivery. Good fit.


A year ago my Casita trailer suffered a hailstorm with tennis ball sized hailstones. While the body is impervious to all that, the plastic fixtures on the outside were shattered. I ordered a number of replacement items from etrailer. I was very happy that etrailer had the parts in stock and sent them immediately. My Casita is fully repaired now.

Easy people to deal with, authentic part, works perfect, easy to install. Fraction of the cost of full unit, which RV shop insisted upon installing.


Great price for sometimes tricky items to find for a 20 yr old 5th wheel. Great customer srvc. Would recommend .


Quick service and provided the correct parts.


Thanks to etrailer, I was made aware that I also needed to replace the old motor (1991) along with the fan due to a design change, saving me time and money. Both items arrived very fast, and the personal emails after the order was placed, and the day it was to arrive was a pleasant surprise for such a small order. Here Here for Etrailer. Thanks - Andy


Exactly what I ordered and arrived very quickly. Prices are very reasonable and I have used etrailer many times. Highly recommend them for great prices and great service.

Still working great and glad I purchased.

There are actually three versions of this fan blade. I was able to make this one work with a little barbering with a needle file. UV light filtering through the dome turns the blade to power after about ten years. Painting the dome will slow this UV aging down. Good to know that Ventline makes parts available for so many years.


Initially, the fans I ordered were not available immediately. But George was able to find them and get them to on the date I had requested them. Now I have a working fan in my trailer head for our upcoming trip. Installation was easy. Well done! THANKS!

-Rob S

Still working well. Second one is in storage for the next time. Thanks for the followup. It is nice to know people still care about their customers. You are at the top of that list.
Rob S - 08/15/2018


Exactly what I needed and promptly ship ped.


Very easy job to replace fan blade, but must be done from above. Original one just crumbled into little pieces. This replacement seems to be made from a much more durable material.

Still PERFECT. Used often, with no complaints. I wish ALL the parts in my RV were this well made.

Product/vent fan blade replacement for Airstream Interstate was as
advertised, came promptly....quite pleased and would do business with
etrailer again....Thumbs up


The original has a flat side on the motor shaft. This replacement has a small hole in the center that i had to drill out so that the unit would slide onto the shaft with a tight fit. worked perfectly.

Still working fine.
Lorne - 09/24/2019


my order came fast, was exactly right, and the prices were super! I will defifnitely put etraiiler on my list of prefered vendors for parts and accessories for our RV. thanks etrailer!!


The fan arrived in great shape, highly recommended for those that have airstream interstate with broken bathroom ceiling fans


Outstanding service. Great products.


Sometimes your lucky if you can find a merchant that either has or can get a product you need. Etrailer is that merchant.


I just received my order , and I have to say. Perfect, yes perfect in so many ways. First , you were very helpful in placing my order. Helping me find what I was looking for. Then you had everything I needed to fix my problem. And at a very reasonable price. I thought it was going to be a joke when you said I should receive. It was no joke. I have it all in my hands. I can not thank you enough.


Actually, the hole in the center does not fit my motor pin. It is supposed to have a half-round hole but the ones you ship to me has a small round hole. So I have to drill it larger and hammer it down. Honestly I don't know if it will work or break soon.


This blade fit well into the old enclosure for the broken blade it replaced. Still working a year later as far as I know.


Product arrived quickly and was a perfect fit and easy replacement for my existing roof vent.


Perfect, just what I needed


Part was an exact replacement and very easy to install. Execellent quality and should last for many years.

    For the P series of Ventline fans, such as Model PH 4, the correct replacement fan motor is # BVD0278-00. Should you have an older motor, you may also need a new fan blade which is compatible.

  • Replacement for Ventline Round Exhaust Vent
    The correct replacement motor is going to be based on the model of your Ventline, and I was unable to reference the information you gave into a model. However, # BVD0218-00 is a replacement for Ventline P, S0721, B, and T Series models. It is a 1-1/2" motor, and if yours is the older 2" motor, you are going to also need to replace the fan blade with either # BVD0215-00 or # BVD0217-00. If your Ventline exhaust fan was model V2045 or V2244, you would need replacement motor # BCD0390-00.

  • Should Fan Blade Be Replaced with Motor Replacement
    It is recommended by the manufacturer to replace the fan blade if you are changing over from an older model motor to a new one because the old blade will usually not fit the new motor correctly.
