AMCA Accredited Air Test Chamber

To be the leader in agriculture ventilation has always been a goal of J&D Manufacturing. We’re extremely proud of our Air Movement Control Association (AMCA) accredited air test chamber. This highly-technical, scientific instrument allows us the ability to design, test, and manufacture fans that perform as designed and advertised. It allows us to efficiently develop and test prototypes and ensure performance ratings are reliable, accurate, and repeatable. J&D is the only company in the United States that has an AMCA accredited air test chamber that is used exclusively for the agriculture market.

Providing accurate performance data is extremely important to J&D Manufacturing. Today, an agriculture fan is part of an integrated system designed to control an environment. Animals obviously cannot survive without air and proper ventilation. When fan performance data isn’t accurate and verified, animals’ wellbeing is at stake, which in turn means your livelihood is at stake. J&D tests and re-tests our fans. In the performance section of our catalog, you’ll notice all numbers in red font are tested, proven numbers.

How the Air Chamber Works

There are four main components to the air chamber; the intake chamber, settling means, nozzle wall, and final chamber. The air enters through the intake vanes, the intake fan, the air straightener, into the intake chamber. It goes through the first settling means which is a series of screens that reduces air turbulence and creates an even flow. Air passes through the nozzle wall, a gauge for measuring the airflow through the fan in test. The air then hits the second settling means and enters the final chamber and exits through the fan in test. The test chamber accurately and repeatably measures fan airflow performance in cubic feet per minute, fan efficiency in cubic feet per minute per watt, and all aspects of the electric power to the fan at any static pressure.

What Does This Mean for You?

When a fan is installed in a barn and power is applied, the fan draws air out of the building and creates a vacuum that is measured in static pressure. Our test chamber creates the static pressure conditions a fan will see in real life applications. When you tell J&D Manufacturing you need a certain airflow, we have the ability to create a custom fan and test it in the same pressurized conditions it will see in your facility. You can trust with 100% confidence that you will receive a fan that performs to your specifications.
