VariTrane™ Fan-Powered Series Terminal


VariTrane™ Fan-Powered Series Terminal

Fan-powered series units offer energy savings due to intermittent fan control.

Product Overview

The fan energizes only in heating mode when the space needs heat. Additional energy savings are obtained by using warm plenum air for free reheat. Motor heat is never wasted in parallel units. They are an excellent choice when minimal zone heating is needed.


  • Interlocking panel design provides the most rugged VAV unit available.
  • Metal encapsulated edges limit fiberglass insulation erosion into the airstream.
  • Single-point power connection reduces installed cost.
  • Full factory-run test on each unit.
  • Pneumatic, electronic, or digital controls available.
  • Compatible with most controllers for field or factory installation.
  • Digital controls allow Tracer® building management system interface for Integrated Comfort™ systems (ICS) capability.
  • Fan is outside primary airstream and runs only when heating is required.
  • Wide range of fan airflows available from single speed motor with speed control.
  • Cooling only (VPCF), hot water reheat (VPWF), or electric reheat (VPEF) units available
