Our History

Fans that make it in rough conditions.

Spendrup Fan Company knows how much abuse equipment gets in debris-filled, abrasive mine environments, and we build tough fans especially for those conditions. You can count on Spendrup Fans for dependable, continuous operations with minimal downtime. We started building fans for uranium and hard rock mines in the late 60’s, and quickly expanded our line of fans to direct, belt or shaft-driven designs for all extreme operating conditions. In 1994, Trent Spendrup purchased the company from his father John, the founder of Spendrup Fan Co. Today, thousands of Spendrup Fans are used in mines throughout the United States, Mexico, Canada, South America, the Middle East and Australia. Spendrup Fans are being used for tunneling, power generation, processing plants and other heavy industrial fields.

Why is a Spendrup Fan so tough?

First of all, we control the entire process-from design to delivery to ensure a quality product. Our team of dedicated employees takes pride in building a tough ventilation fan, and our 48,000 square foot manufacturing facility boasts the latest technology.

Here are some of the process:

  • Our engineers use the most current design software and ¬†solid works 3D to design each custom fan. They’ve designed thousands of custom fans and can walk you through the process to ensure you get the exact volume and pressures you need. Our engineers can also help you select the accessories you need from silencers and inlet cones to explosion-proof design.
  • Our 48,000 square foot manufacturing facility includes over 18,000 square feet of new fabrication floor space with the latest in technology. From our CNC plasma cutting table to our 88-foot overhead bridge crane, we’ve got the setup to build tough fans.
  • With our complete test facility, Spendrup tests all fans in accordance with AMCA 210-84 and ASHRAE 51-17 codes. We guarantee that Spendrup fans will deliver stated volumes and pressures and will be free from defects in materials and workmanship for 18 months from date of shipment. It’s easy to stand behind our product when we have such a solid operation.
