Customer Testimonial
"Working with CB Pneumatics has been nothing but a great experience and they provide an outstanding product. Our new diesel powered grain vac (CB68MPT) out performs others in many different ways in terms of capacity to being more versatile. Their service after the sale is another thing that sets them apart from others cause even though we are 500+ miles away and I have a problem it's solved faster than I ever expected."

Our History

Custom Built Pneumatics was founded in 1980 in Minnesota. The team specialized in developing pneumatic (air) systems designed to gently and efficiently move grain and other various materials from point A to point B.

In 2023, Eric Johnson purchased Custom Built Pneumatics and moved manufacturing to Aplington, Iowa. As an 18 year customer of the business and owner of 12 vac systems for Johnson Seed & Grain Services, he is excited to continue the legacy started so many years ago.

The Iowa based CB Pneumatics team will specialize in manufacturing pneumatic grain vacs and material transfer systems. We look forward to growing the Custom Built name and building the best pneumatic systems in the world.
