Certifications, vary by model

The TMX is designed for supply, exhaust, or return air applications. Performance ranges from 410 to 24,400 CFM with static pressures to 3” w.g. The TMX is offered in 12 sizes from 90 to 330. With the Cook Contour® axial-centrifugal hybrid impeller, these mixed-flow fans are more efficient than traditional centrifugal units. This provides you the opportunity to reduce motor horsepower and fan sound levels while using a smaller unit. The TMX will replace traditional tubular centrifugal and vane axial fans in most applications. The TMX is an ideal solution for critical applications where low sound, high efficiency, or compact size are requirements.

  • The Cook Contour® mixed flow wheel combines the high airflow features of an axial fan with the pressure capabilities and static efficiency of a centrifugal blower.
  • The TMX utilizes a relatively large diameter wheel in a small housing which results in slower wheel speeds and quieter operation.
  • The TMX is more efficient than a square or tubular inline centrifugal and more economical than the QMX.
