2.5" Intake Vents for Shipping Containers

Remember that uniform air movement is the key to good ventilation. You need a balance of intake vents and exhaust vents to make any ventilation system work well. These 2.5" intake vents are the ones we recommend you install on your shipping container near the floor so air movement will come in low and help push the hot air out of the exhaust vents at the top of your shipping container.

Price for a Set of 4: $20

BEST DEAL: For every two Conex Solar Blaster products (RoofBlasters or LightBlasters for Conex containers) purchased, you'll receive a set of 4 intake vents for FREE. Must be purchased together in one order. Add it to your cart BEFORE checking out. Your receipt will only show 1 set of 4, but we'll add the correct amount when packing your shipment.

SealBlaster Sealant

NOW AVAILABLE with vent purchase

Purchase our SealBlaster Sealant so you have the proper caulking to use on your vent installation. The sealant is clear in color so it matches any application. This caulking is completely compatible with our products and their installation procedures. It can be installed in wet conditions and is compatible with all roofing applications. 10.2 fl oz tube.

To get free shipping on the sealant, you must order no more than one tube per vent or LightBlaster product on the same order — as that is what can fit inside each Solar Blaster vent and LightBlaster box. The sealant does not qualify for free shipping if purchased separately (*see note about ordering larger quantities).

Ventilation is Key for Steel Shipping Containers!

If you plan to store equipment you don't want to get rusted or damaged due to moisture and heat inside your steel shipping container, you need to ventilate your container sufficiently. We recommend 1-2 vents for every 20' of container. Remember, that uniform air movement throughout your entire container is important. You will need intake vents down low as well for fresh air to enter your container so the hotter air rises and exhausts out of the vent on your container's roof.

NEW Solar Mega RoofBlaster for Conex Shipping Containers

We have designed a new ventilation solution for Conex shipping containers that is built in the same vent but has a larger, more powerful fan (120mm; 96cfm) and 5W solar panel.

Military Use of Shipping Containers

Solar RoofBlaster ventilation solutions can improve military shipping container work conditions

Solar RoofBlaster vents and LightBlaster tubular skylights have been installed on many military containers, sheds and other temporary military buildings.

These temporary work and storage stations don't have to have unbearable working conditions inside of them. Our Solar RoofBlasters vents for Conex Containers bring in fresh, cooler air and expel the hot air allowing air to circulate throughout the container anytime the sun is shining. The fresh air will also help remove odors, gas fumes, etc from smelling up the container. Proper ventilation helps mediate moisture buildup through uniform air movement.

With our LightBlaster tubular skylights, you can light up the container with natural light at no cost any time the sun is shining.

Take a proactive approach to improving the military containers on your base.

Trust us, you won't regret it. No one should have to work inside a sauna. Let us help you convert your containers to a workable space.

History & Development of the Conex Storage Containers

  • The Transporter

    Open or Close
    Stacks Image 1610
    Predecessor to the CONEX.

    As early as World War II, the Army began experimenting with using containers for shipment of supplies to the theater. Cargo was delayed at ports due to time required to load and offload ships. The Army was losing money because of pilferage and in-transit damage.

    In 1948, pilot models were developed and the Transportation Corps adopted the "Transporter, Household Goods, Shipboard" which was commonly referred to as the Transporter.

    The Transportation Corps procured 67 "Transporters" for testing, and along with commercial units, they were tested for household good shipments between the US and overseas theaters.

    The Transporter was a rigid steel reusable container capable of carrying 9,000 pounds. It was 8'6 long, 6'3 wide, and 6'10 high. It had a double door on one end, was mounted on elevated skids, and had lifting rings on the top four corners.
  • The Transporter in Korea

    Open or Close
    Stacks Image 1612
    In 1951, an additional 100 Transporters were purchased for use within the Far East Command. Used to ship items from Japan to Korea, and then by rail to forward supply points, they were evaluated for transporting sensitive, critical, and valuable items.

    This experiment, along with the study of household goods shipments, demonstrated the effectiveness of the container against damage and pilferage. It also proved the efficiency in movement of various troop materiel from the US to overseas commands.
  • Conex is Born

    Open or Close
    Stacks Image 1614
    At the Port of Pusan, Korean stevedores were dropping and breaking almost 90% of the off-loaded crates. Theft and pilferage became a daily occurrence. The Army was losing 10% of all subsistence coming through the port.

    In late 1952, the Transportation Corps developed the Container Express (CONEX), replacing the "Transporter". Engineering supplies and spare parts were shipped from Columbus General Depot (Georgia) to the Port of San Francisco where they were loaded on ships to Yokohama, Japan, and to Korea.

    Not only did the CONEX reduce port pilferage and breakage, it also significantly reduced transportation time. A shipment that normally took about 55 days to deliver was reduced to 27 days.
  • Containers in Vietnam

    Open or Close
    Containers became the backbone of logistics support for Vietnam, and nearly every major Army unit moving into the theater carried their spare parts and supplies in containers.

    Many containers never made it back from the theater; they were employed as command posts, dispensaries, portable stores, bunkers, and so forth. The containers provided millions of square feet of covered storage that the theater lacked.


    Above, in transit cargo is staged in Cam Rahn Bay here, operated by the 403rd Transportation Company (Terminal Transfer). Visible straight ahead in the center is passage to the South China Sea.

    Cam Rahn Bay, Vietnam. This photo clearly shows some of the numerous containers used as storage for spare parts and supplies.
  • Commercializing Containers

    Open or Close
    Stacks Image 1623
    Commercial industry began to develop methods of moving containers. During the Vietnam conflict, Sea-Land Container Services, Inc first introduced containerships designed only to carry containers.

    Inter-modal containers were developed to be shipped via rail, truck, air or ship. Today, they are used commercially as well as by all military services. The use of inter-modal containers may possibly be the most valuable element in global transportation in most industrialized countries.
