Features Include:
  • Easy to install in-line as part of standard air duct.
  • Durable, patented HMI  HOYME 'spring motor drive' with nylon bearings.
  • 26 ga. galv. steel from 4" to 5" dia.; 24 ga. galv. steel from 6" to 9" dia.; 24 ga. galv. re-enforced steel from 10" to 14" dia.; 22 ga. galv. re-enforced steel from 16" to 18" dia.: Other sizes and weight of steel upon request.
  • These dampers can be used for the new ventilation code which requires a designated exhaust fan, a centrally located switch marked 'VENTILATION' and a fresh air intake damper, all interconnected to the furnace circulation fan. See HMI  Interface Relay Adaptors' which have been specially designed for these dampers and new ventilation codes.
     
Other options that may be added:
  • Adding Insulated wrap at the factory
  • Using Stainless Steel instead of galv. steel.
  • Adding an End Switch
  • Adding a Relay
  • HCR - Economizer for use with Air conditioner
  • Mounting Collar is included but may be left off
  • Interface Relay Adaptors permit connection to Line Voltage controls.

Series HAC dampers can be supplied with: spring returned with Power Open / Power Closed (field change from PO to PC or vice versa); or powered both open and closed with relays (wiring diagram for PC with relay); or with three wire switching.
