We Prevent “Container Rain”

On – Grid or Off – Grid.  Introducing the U.S. MULTI-PATENTED

Technology so effective it can prevent condensation and excessive heat buildup in a Conex/Storage container using only outside air movement to “CREATE” the needed 24/7 airflow. Door/Wall mounted means no more need for turbine units requiring holes in your roof!

It really works! Check it out

Our game-changing DRY-CON X ® System has no moving parts to wear out, needs no maintenance, has built-in screens and weather protection, requires no screws, rivets or welding and works 24/7/365 using nothing more than outside air currents for a power source. For what truly sets us apart, technical details, and real-life test results, read the full details below.

What makes us different?

What makes us your best choice for shipping container/conex venting solutions? We invented, manufacture, and market our own patented “flow through” technology to address the complex venting challenges of re-purposing a seagoing shipping container (conex) into a reliable storage facility.

How does it work?

No need to spend any more time figuring out how to prevent “container rain” or deal with excessive heat build-up using those old and ineffective “DIY” projects. Our game-changing DRY-CON X ® System requires no moving parts to wear out, needs no maintenance, has built-in screens and weather protection, and works 24/7/365 using nothing more than outside air currents for a power source to “PULL” outside air through your container. And best of all, our vents are made to fit your container door/walls  with no welding, screws, mechanical fasteners or modifications needed!

Door Mounted Wall Vent Exhaust with Vent Locations General Exchange Locations

Our revolutionary DRY-CON X® design is the only system ever invented that uses no moving parts and does not require an outside power source other than air movement to provide a truly continuous air flow through your shipping container/conex. Perfect for “Off-Grid” applications where electrical power is not available or desired.

Continue exploring our website to learn how we can give you the best protection available regardless of your climate conditions.

Yes, it really works. Here’s proof—

We already know that traditional louvered venting can not create the “drive” necessary for continuous air exchanges and is not an effective solution when you need constant airflow. It’s an engineering fact. Our multi-patented technology now makes that possible. Explore for yourself!

360 Products sets the standard for easy installation – No tools required after hole cutting

Once the vent locations are determined, mark the port openings as per the cut-out instructions for both the Exhaust and the Intake. For step-by-step walkthrough, read the full details below.


  1. Once the vent locations are determined, mark the port openings as per the cut-out instructions for both the Exhaust and the Intake, as below.

2. Cut the rectangle holes, clean off filings

3. Prep the mounting surfaces with the abrasive sanding block now provided. Clean thoroughly and apply rubbing alcohol (IPA) diluted by 50% water. Dry with a clean rag.

4. Remove the red protective cover from the tape backings on the vents, and press the vents in place

5. Press well for about a minute to make sure initial contact is made. Cure is secure at 40% (after 20 minutes). The “Exhaust Driver” has two parts, port then cover. Intake has one part. The 3M® tape takes about 24 hours to cure completely.

Container with Installed Wall Vent

6. The 3M® brand commercial grade tape has outstanding adhesion properties and provides an excellent weather seal. To compensate for container imperfections, an exterior sealant is still required for the top of the intake and the top and bottom of the adapter plates (if required). For the extra minute it takes, we suggest applying a bead of sealant around the outer edges of all the vents and parts.

You are done…Simple as that!

Note: There are literally hundreds of sealants in small, individual tubes available at all Hardware/Home Improvement stores across the country. We recommend asking their sales associates which ones they would recommend for a small, one time application such as ours.

Vent Placement

The goal is to maximize the conditions of the container location, it’s size and how it’s positioned regarding wind direction, wind obstacles and sun / shade. To allow for these variables we have products specifically designed to fit the contours of different walls. For considerations, intake, vent quantity, and notes, read the full details below.

Planning My Container Vent Locations

Vent Options: The goal is to maximize the conditions of the container location, it’s size and how it’s positioned regarding wind direction, wind obstacles and sun / shade. To allow for these variables we have products specifically designed to fit the contours of different walls. The “Wall Exhaust” pictured will automatically fit the flush surface of the doors but can also be installed on side or end walls using the appropriate adapter plate.  “Intake” vents are automatically contoured to fit the individual side and end wall corrugation.

See “Vent Placement” for designing the optimum ventilation system.


  • Spend time on site to determine what end gets more wind.
  • Gusts, turbulence, unnoticeable winds, and thermals actually help to enhance ventilation performance.
  • See “Low Winds and Air Exchange Tables.
  • General rule: A 20 ft conex will need 1 exhaust/1 intake, a 40 ft. will need 2 exhaust/2 intake.  See the above link to determine. In hot and humid climates 2 exhaust and 2 intake vents have provided the greatest on site performance for 40′ and high cube units.


Regardless how many of the small stock rectangular vents (See “Stock Vents and Comparisons”) are presently on the walls, a proper intake will be required at the opposite end of the Exhaust. This will allow air to be “PULLED”by the exhaust driver throughout the entire container. One intake can feed 1 exhaust vent. Side walls are a different profile than rear walls, note the screen shapes provided here.

Determine Vent Quantity

A 40 foot container needs more ventilation than a 20 footer. The formula works based on how many air exchanges can be completed each day.   See “Low Winds and Air Exchange Tables”.

Please Note

Keeping a large metal box condensation free without power is not always simple as some locations are tougher than others. For the best performance with our product, download our free guide, “8 Steps to a Dry Container,” and implement whatever is possible.

We want success for all our customers, so please review all the links listed above to ensure all the variables have been considered when designing your ventilation system and we welcome your call if you have questions.



I just wanted to let you know that the vent system I bought from you back in November 2021 has been working out great in my 20 foot container. I wanted to take it through “all the seasons” here in central Virginia where we have moderate temperatures in the winter and very high humidity in the summer before I sent a review. No condensation or fumes inside whatsoever! Very satisfied.”

Grain Storage in Texas!

“I can’t explain what a difference your product has made for my container. On a day like yesterday with high heat and humidity the inside of that container would normally be unbearable. Thousands of pounds of feed, a sealed container, high heat and humidity created toxic fumes that were overwhelming. Your venting system has corrected these issues and now my container is comfortable to enter even on these extreme days.

Thank you for a great product!”

Note from 360 Products: John has reported to us that he has zero grain loss now since installing the vent system over 1 year ago. This was beyond even our expectations in a situation this complex.

Hi Bob,

We installed the 2 sets of vents on my 40’ container 3 weeks ago. I’m happy to say, when you swing the doors open, there is little or no odor coming from the insecticide treated floors. I have begun to store items in it and feel confident the problem is solved. Thank you very much for speaking with me for nearly an hour and making me feel like the concerns with my container were important to you. That is very rare in these times. It was a pleasure doing business with you.

Goodbye Gas Fumes

“I recently reached out to the experts at 360 Products to help with ventilation of my 40′ shipping container used to house equipment for our construction business. Gasoline fumes were overwhelming before I installed their products. This system requires no electricity and totally solved our issue. Customer support is second to none. I highly recommend this company. Thanks for the fresh air!”

“Wanted to let you know that I am impressed with your Vents. Also, really impressed that you answered your phone on 4th of July to help me. I realize that you did not have to do so and most would not have. Customer Service is extremely difficult to find anymore. I have told several friends about you. Thank you again for your help and expertise”

“I have no problem with you sharing our feedback, especially to fellow Naval personnel. [Y]ou’ll be pleased to hear that my supervisor had a chance to see the finished product after the install I did, and he is very pleased that not only the obvious functionality of the vent (feeling the breeze, he said), but also the aesthetic look the[y] add. We are definitely satisfied with your product and would recommend it to anyone in need of such a thing.”

6 Week Follow-Up

“The vents are doing a fantastic job and seems to be mitigating any form of moisture intrusion inside the Conex. All in all you have much to be proud about with this outstanding product and we would be happy to recommend it to anyone.”

Yesterday when I started (installing the container vents) over half the container had “container rain.” Today the container ceiling is completely dry and the floor is much drier. And it rained overnight!

May 31, 2019 – UPDATE 2 WEEKS LATER!

Those vents have now been on the container for almost 2 weeks through record rainfall. The container is drier than it has ever been and the gear stored inside is beginning to not smell musty. I’m shocked at how well this has worked!

School District’s Mildew Problem Solved

“I installed your 360 container vent system back in Sept 2019. I am reviewing this product a year and five months later. I used two intakes and two exhaust per 40 foot container as suggested. We had a terrible problem with container rain and mildew build up. After we installed this system we cleaned all the mildew off the ceiling of four different containers and have not had a problem since. These vents work! Thanks Bob for your help in deciding to purchase this product.”
