At DMC Sales, we do more than just help you select and deliver the right fan equipment — we partner with you to ensure it keeps performing at its best.
Through our trusted manufacturing partners, we facilitate a full range of on-site fan service, troubleshooting, and reverse engineering solutions. Whether you’re facing startup challenges, operational inefficiencies, or unexpected component failures, DMC Sales serves as your direct link to factory service experts — ensuring issues are resolved quickly and correctly.
On-Site Fan Service & Support We have fan partners that offer on-site startup services, system diagnostics, and troubleshooting for fans currently in operation. These factory-trained teams can bring advanced test equipment to your site and evaluate fan performance in real time, helping identify problems before they lead to costly failures.
All coordination runs directly through us, so you don’t have to worry about managing multiple vendors or service contacts. We gather the technical details, communicate with the factory, and ensure the job gets done right.
Reverse Engineering Capabilities Got a fan wheel or housing that failed — and you’re not sure who originally manufactured it? That’s where our reverse engineering service can help. If you can provide basic operating specs (RPM, CFM, static pressure, materials of construction, etc.) and general dimensions, our manufacturing partners can often reverse engineer a replacement.
Typically, the failed component is sent to the factory for detailed teardown, measurement, and engineering analysis, and a fully compatible replacement is built — even if the original manufacturer no longer exists.
Territory Support & Flexibility Our services are typically available across Northern Illinois and Northwest Indiana, but we may be able to assist outside this region on a case-by-case basis.
If you’re unsure whether your facility qualifies, just ask — we’re happy to check and let you know. If we can’t help you directly, we’ll help you find someone who can.
Let’s Get Started When you're dealing with an urgent fan problem, need assistance with reverse engineering, or want expert advice before scheduling service, contact our team. We’ll respond quickly to reduce downtime, simplify the process, and ensure you get the right solution from the start. 👉 Contact us.
Frequently Asked Questions
