A good shipping container ventilation design will include a balanced passive ventilation system. What that means is for every inch of air exhausted out of the shipping container, there needs to be a balanced amount of air coming in through lower intake vents. You should never install only exhaust or only intake vents on your shipping container. They must be balanced in order to effectively achieve air movement.

Having a balanced passive attic ventilation system also means that there is uniform bottom to top air movement across the ENTIRE length of the shipping container.

Air movement is crucial to maintaining a healthy environment. Proper passive ventilation allows the container to breathe and has the following benefits:

• Expels heat.
• Expels moisture.
• Reduces cooling costs. 
• Reduces any wood from rotting inside.
• Reduces risk of mold and mildew growth. 
• Improves interior air quality.
• Works all year around.

Once you understand about the benefits of a balanced passive vent system, boosting the effectiveness of that venting system is the advantage that Solar Blaster brings to the table. Multiple solar-powered vent fans will more effectively remove the hot, moist air out of your container and they aren't reliant on just convection and wind to make it happen. And yes, they are passive vents anytime the sun isn't shining. We love the irony that we are utilizing the source of the heat problem, the sun, to also be the solution for removing the hot, moist air in shipping containers. With multiple smaller solar-powered vents, you now have these benefits:

• Expels heat faster.
• Expels moisture faster.
• Reduces cooling costs more.
• Reduces wood rot more effectively.
• Reduces risk of mold and mildew growth more effectively.

• Easy to install.
• Less expensive than larger solar-powered fans. Bigger is NOT better (see that section below).
• Uses the source of heat to be the solution at no additional cost.
• Multiple fans don't leave hot spots.
• Does not require thermostat control.
• Works even on non-windy days.
• Installs from the top of the container.
• Works even on slightly cloudy days as the fan will start at a slower speed.
• Activates passive vents to make them more efficient. 
• Multiple fans promote uniform air movement across the entire Conex container.

Wind turbine vents require wind to operate so on still, hot and humid days, they do not operate. In addition, to be effective, you would need to place those ugly whirly bird vents across your entire shipping container's roof.

Do you really want multiple of these less-than-appealing vents up on your container's roof that only operate in certain weather conditions? Wind turbine ventilation is not your best choice for venting your Conex box.

As we've said already, the sun is the source of the problem (not the wind), so allowing the sun to also be the solution is ideal. So regardless if the wind is blowing, when the sun is out, your vents are supercharged to exhaust that hot air. It's the best solution around.

Multiple, smaller solar fans that also act as passive vents are a much better and effective system. Passive vents should be spaced evenly across the entire length of one's container and by adding a SolarBlaster vent solution to each vent, your vents will be much more effective in exhausting the hot, moist air.

Also smaller solar fans require less power to start operating so our fans will work even on slightly cloudy days. They also don't require an on/off switch or thermostat to control them.

Remember, you want your passive vents to be working all the time day and night. With SolarBlaster's products, you can now activate your passive vents so the sun can start removing its own hot air during the day!

Shipping containers go by many names — storage container, sea container, ocean container, freight container, cargo container, intermodal container, ISO container, sea can, c-can, moving container, dry container, and insulated container — but they all share the same ventilation challenge: trapped heat and moisture.
