ITEM NO. _______________
MODEL AirVantage (DCV-AV)
DEMAND CONTROL VENTILATION
WITH SMART READ AND REACT TECHNOLOGY
FOR MULTIPLE HOOD SINGLE FAN EXHAUST SYSTEMS
GENERAL SPECIFICATIONS AND DESCRIPTION
Furnish Gaylord Demand Control Ventilation (DCV) with smart read and
react technology Model “DCV-AV” (AirVantage) as shown on plans and in
accordance with the following specifications:
DCV-AV AIRVANTAGE SYSTEM DESCRIPTION: The purpose of the 7
DCV-AV (AirVantage) system is to reduce kitchen operational and util-
ity costs by conserving energy through the reduction of exhaust and
makeup air for the commercial kitchen ventilation (CKV) system while ef- 7
fectively communicating with the Building Management System (BMS). 7 3

• The AirVantage Command Center housing shall be constructed of 300 1
series stainless steel with a #4 finish complying with NSF/ANSI 2-2010. 5
• Shall utilize listed, programmable stainless steel resistance tempera- Override Button
ture detectors (RTDs) mounted inside the hood canopy to accurately
read sensible heat from the cooking equipment and vary the speed of
the exhaust and makeup air fans accordingly.
• Shall be able to control multiple hood sections, exhaust fan, and
makeup air fan on one system. Additional systems may be required AirVantage
