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.

Capacity and electrical information

The maximum humidity dispersion capacity of each EHF-2 area fan package is 30 lb/hr (13.6 kg/hr). The maximum humidity dispersion capacity of each EHF-3 area fan package is 120 lb/hr (54.4 kg/hr).

NOTE: The EHF-2 fan package requires a separate 120 volt power supply.
