WITH SMART READ AND REACT TECHNOLOGY
MULTIPLE HOOD MULTIPLE FAN EXHAUST SYSTEM

GENERAL SPECIFICATIONS AND DESCRIPTION
Furnish Gaylord Demand Control Ventilation (DCV) with smart read and
react technology Model “DCV-AVND” (AirVantage No Damper) as shown 6
on plans and in accordance with the following specifications:
DCV-AVND SYSTEM DESCRIPTION: The purpose of the DCV-AVND
(AirVantage No Damper) system is to reduce kitchen operational and 6 6
utility costs by conserving energy through the reduction of exhaust and 3
makeup air for the commercial kitchen ventilation (CKV) system while 5 5 5 HCE
effectively communicating with the Building Management System (BMS). 5
