I have a commercial reach in cooler in my food truck. The compressor sits on the top. I took a temperature reading at just over 200 degrees on a 89 degree Florida day. After installing the Redline vent, the temperature has never gone above 105 degrees. That's a 100 degree difference! I did not use the butterfly damper as i wanted it to be always open. i added a vent cover with a sleeve, because of the 3" gap in the ceiling.

Looking at the picture of the truck you can barely see the vent top from 25' away. I didn't need more drag going down the road. With the low profile of the vent I get rid of heat and no drag. Perfect.


Comments
After having this product installed for a year it has performed flawlessly. No water drips in, and we have some pretty good daily storms in Florida. Evacuates the heat so when I enter the food truck I dont get slammed with heat. I think I need to put one on top of my pick up. When I get in it I can hardly breathe .

Using a couple of these to ventilate my trailer, right where the fan on the jetter's engine is located. The baffled design seems well suited to provide ventilation without allowing water in. Construction seems sturdy albeit a couple fins were slightly bent. Didn't matter to me though since this is a work trailer.

I don't think it came with instructions, but then again, you're probably handy if you're buying this yourself. The loctite sealant on this site seems well suited for the job. Yes, I had some overage and installed this in low light conditions but hopefully I can clean it up later. It's tough stuff.



by:

The vent is substantial- well made. I couldn't find a replacement for a broken vent cover that was large enough until someone at etrailer suggested this one. It turned out to be an excellent solution.



by:

Received the product in a timely manner. It had a small dent but I still used it. Technically the vent should be installed in s roof surface. I installed it vertically in the back door of my Promaster van. Recently I installed a Fletner rotary vent on the roof. This vent is my makeup air for the flettner. Can't beat it for the price. Simple and durable.



by:

Could have used a paper template for hole layout patterns. Well made, should keep the elements out.



by:

Items purchased were as advertised. Decent quality. Nothing spectacular, but what I needed for my trailer.

The part of this transaction (not my first purchase from etrailer), is when there was a product availability issue, an etrailer representative telephoned to let me know of the delay. Later, etrailer sent a shipping status email.

Online shopping has its pros and cons. etrailer obviously has their act together to ensure top customer service!



by:

We used these vents to provide air circulation on a used 8' x 20' box/shed from an old box truck. The E-Track sockets gave us shelf supports for more storage in the box. All products worked well.

Great experience with etrailer. Ordered a Fulton Spare Tire carrier and Roof Vent and my shipment arrived in 3 days. Fast delivery! I had to exchange the roof vent and couldn't be happier with etrailer.com customer service. Fast, courteous and the exchange was hassle free. I had the new vent in 3 days even before returning the original one. It just doesn't get any better than etrailer.com



by:

High quality products at a good value delivered on time; that's been my experience with etrailer so far. Website's easy to use as well.

I bought two of these for a 16' trailer. They are even better than I had hoped for! Fast service, great product, good packaging.

Great piece to work with. Works as you would want.

  • What Color is 2-Piece Side Vent for Enclosed Trailers # 9139
    The color of the 2-Piece Side Vent for Enclosed Trailers # 9139 is a glossy white color. The color does look misleading next to the white background but it definitely is solid white. If you check out the picture I attached you'll see it installed on a white vehicle and you can see that it is totally white.

  • Will 2-Piece Side Vent for Enclosed Trailer # 9139 Prevent Dust From Getting into Trailer
    If you close the vent of the 2-Piece Side Vent for Enclosed Trailer # 9139 you'd greatly reduce dust getting into your trailer. It's not air tight though so some might make it through but I wouldn't expect it to be a level that you'd notice.

  • Can the 2-Piece Side Vent for Enclosed Trailers Be Used To Vent Trailer for Generator
    The 2-Piece Side Vent for Enclosed Trailers part # 9139 will do a fine job of helping to vent the trailer for your generator. It looks like we have had a few customers use the vent for this exact purpose. If needed, you could install multiple side by side as well.

  • Metal Side Vent for Enclosed Trailer
    The best option for a metal side vent for your enclosed trailer is the 2-Piece Side for Enclosed Trailers - Metal - 10" x 12" # 9139 because its exterior will shed rain like you wanted, has a butterfly vent which you can turn if you wanted to adjust the amount of air flow. Though it does not have a screen you can easily add one as part of the vent to keep the bugs out of your trailer. This vent will simply require a 6" diameter hole and you will need four 10/32 machine screws to install...

  • Availability of Side Vents for Toy Hauler Trailer
    For trailer side vents we have a couple options but none that are 9 inch by 9 inch. We have the part # 9139 which is 10 by 12 inch and the part # HMAV2-AVT2 which is more of a semi-circle shape that is 6 by 8 inch.

  • Function Of Trailer Vents On Enclosed Trailer
    The vents we offer for an enclosed trailer like part # 9139 are designed to allow air into the trailer. None of the vents we offer create a pressurized condition in the trailer and none are equipped with an air filtration system to keep dust out. Some of the features on the vents like # 9139 allow you to adjust the amount of airflow in the trailer with a butterfly valve mounted on the inside of the vent which would be operated from inside the trailer. Other trailer vents, like part #...

  • Attaching the Redline 2-Piece Roof Vent to the Front Side of a Cargo Trailer
    Yes, you can mount the Redline 2-Piece Roof Vent, # 9139, on the front side of your cargo trailer. You will want to mount this vent with the vent slots facing down to prevent rain water or other elements from getting into the trailer. If you are looking for vents for the front side of your trailer, then I would recommend the 2-Piece Polypropylene Trailer Vent, # HMAV2-AVT2. This vent is designed specifically for the sides of trailers and is an inexpensive option that is also available...

  • Best Mounting Orientation of WAVT2-WHMAV2 2-Piece Polypropylene Trailer Vent
    If you mount the Redline 2-Piece Polypropylene Trailer Vent # WHMAV2-WAVT2 with the exterior part's flat slotted side facing forward (to increase air flow) there will definitely be a greater probability for rain and splashed water to enter the trailer. Still, as you noted from the customer-submitted photos we show on that item's page some have done this, and surely for the same reason. If you happened to stay in dry/desert areas this will be less of a concern but since you are in the...

  • Recommended Vents for 10 x 20 Foot Shed
    The only vents we have that will work for the shed walls are manual open and close. The 2-Piece Side for Enclosed Trailers - Metal - 10" x 12" # 9139 is the nicest option and will close from the inside for the winter heating. You can use the butterfly vent # 371800 on the exterior if you so desire but it gives you not interior help. The Side Cowl Ventilator with Screen # PLR1715 is the option I recommend because of your desire to open from the outside. This has a gasket for a nice...

  • How Does Enclosed Trailer Vent Keep Rain Out of Trailer?
    The enclosed trailer vents we offer are designed to keep the rain out and the best option would be the 2-Piece Side Vent for Enclosed Trailers # 9139.

  • Can 6-1/4 Diameter Ventline Vanair Trailer Roof Vent be Installed on the Wall
    Although I'm sure you could mount the Ventline Vanair Trailer Roof Vent # VP-543SP vertically on your wall, when I reached out to my contact at Ventline he said that it wasn't built to function that way so it may not operate properly. You could instead install a wall vent like part # 9139, # HMAV2-AVT2, or # WHMAV2-WAVT2 to help promote airflow if you don't want to/don't have room for an electric vent on your roof.

  • Selecting Replacement Trailer Roof Vent
    Trailer roof vents that are square in shape are usually 14 x 14-inches and are intended to fit a slightly larger 14-1/4 x 14-1/4-inch rough roof opening. I linked our main page for all roof vents; these include a majority in the 14 x 14 size but others are offered as well. The best way to proceed is to remove the old vent so you can measure the dimensions of the trailer's opening. But you can also measure both the interior and exterior dimensions and get pretty close. We have only one...

  • Solar Powered Roof Vent for Cargo Trailer
    I have a solution for you, it is a smaller fan unit but we have an item that will function in the way you are looking for. The MaxxFan Mini Plus Manual RV Roof Vent, # MA00-03851 that you linked to needs a fairly stable power supply of 12 VDC and draws slightly less than 2 amps to operate. Wiring directly to solar panel will not support this as the power will fluctuate greatly and eventually damage the electronics in the in the fan. To operate, you need a stable 12 VDC power supply from...
