1. Balancing Dampers would typically be used when two or more Ventilators are connected to a common exhaust fan The purpose of the Balancing Damper is to raise or lower the airflow of each Ventilator to achieve the desired exhaust rate Balancing Damper Options The three damper models available are as follows 1 Model SD Slide Damper is located in the plenum at the entrance to the duct collar Refer to Figure 4 7 1 The damper is a two piece system that slide across the duct opening to increase or decrease to opening size Adjustment is made by removing the filter Extractor under the exhaust duct collar and reaching up with a wrench loosen the set nuts and sliding the damper plates to the desired position After confirming the airflow tighten the set nuts Set Nuts Exhaust Duct Collar ae E Top of Ventilator Plenum an Sliding Damper Figure 4 7 1 Plan view of Sliding Damper Chapter 4 Testing and Repair Page 4 8 Balancing Dampers Cont 2 Model GBD Gaylord Balancing Damper is a manually adjusted blade type balancing damper with internal setting Refer to Figure 4 8 1 Adjustment is made by removing the filter Extractor under the exhaust duct collar and reaching up with a wrench to the Adjusting Nut The nut is loosened dampers manually adjusted to the desired position and the Adjusting Nut retightened The distance between the damper blades at the top is called the Damper Set Dis
