VAV Electronic Diffuser from Specified Controls

Zone One is a cost effective control damper assembly designed to solve over-heating and over-cooling problems. It can be used to control a single room, or by using multiple dampers to zone multiple rooms. Zone One is available as two-position or modulating and with a damper or diffuser.

Diffusers incorporate an internal modulating disk that continually regulates the volume of supply air in response to a wall-mounted thermostat for an individual zone. The VAV diffusers is designed to maintain coanda eff­ect (draft free) of discharge air along the ceiling, providing a sustained velocity throughout the volume range. 

Operating the diffuser from an individual wall mounted thermostat enables users to choose their own desired level of comfort control from desk top level, rather than a stratified ceiling level.

Key Features

  • Wall-mounted thermostatic control
  • Powerful, low-voltage actuator
  • True variable air volume in heating and cooling modes 
  • Adjustable minimum and maximum airflow volumes ranging from 118 to 710 CFM
