Balance your flow with MAS. Van Metre Expert Casey Fauvre Shows How to Adjust Your Dampers According to Season. These are not for closing off a duct completely, they are simply for “balancing” the airflow in a system to the desired levels. This results in a non-uniform velocity profile beyond the damper, and flow to branch ducts close to the downstream side may be seriously affected (See Figure6-4). Its important to know the difference between these two types of dampers. HVAC systems circulate air through the connected duct work and maintain adequate air pressure throughout the building. Grainger Canada has been Canada's premiere industrial supplier for over 125 years. In order to improve efficiency and occupant comfort, HVAC systems are commonly divided up into multiple zones.
