Quality Assurance


How can Mainstream offer a 2-year warranty on fan array systems? Our fan arrays are USA-made and factory tested. We ensure easy installation and smooth operation.

We’ve had fan arrays in operation for years without a single maintenance issue. If an issue does arise, our experts are there to offer service and support. If a fan should fail within the warranty period, we make it right.

Quality Products

When it comes to quality fan arrays, Mainstream leads the industry. With over 30 years in business, we understand what it means to stand the test of time. Like our company, our products are built to last.

With N+1 redundancy, the other fans in the system can easily compensate for a single failed fan. Our fan arrays include 2-year parts and labor warranty. In the unlikely event of a fan failure, we ensure quick resolution.
