EHF Fan Packages for Area-Type Distribution


The Armstrong EHF fan package provides humidity distribution when an
air-handling duct system is not available. The attractive EHF units are
designed to be used with Armstrong atmospheric steam units and provide
these benefits:

  • Versatility. The EHF-2 unit may
    be installed directly on top of Model EHU-701 humidifiers. The EHF3 unit
    will mount directly onto the EHU-703. The fan packages may also be hung
    on a wall—permitting the introduction of humidity with any atmospheric
    humidifier mounted in another area.
  • Rugged steel construction. Fan package cabinets are made of 18-gauge steel and finished with tough epoxy enamel. The color is matched to the EHU family.
  • Long fan life. “Air-over” design cools the blower motor for long operating life.
