 ''While they may affect airflow, opposed blades do serve an important role in your HVAC system. The opposed blade action can modulate airflow and provide more torque to the blades while in the closed position. Tighter seals between each blade will minimize air leakage in the process. Opposed blade orientation is best for modulating airflow at different points in the duct.''

			Q: Was asked about opposed blade and parallel blade dampers and when to use each.

			A: S-4 standard control damper uses opposed blades and we should only use parallel blade dampers when required by customer/sales department. Below talks about the difference. Generally we need to leakage to be as low as possible and the opposed blades are better for this.

			[https://newsstand.mcdlg-hvac.com/parallel-or-opposed-blade-orientation https://newsstand.mcdlg-hvac.com/parallel-or-opposed-blade-orientation]

			''The Difference Between Parallel and Opposed''

			''While the results may look the same, these two blade orientations have trade offs that make them better suited for certain applications. When opening and closing, parallel blades minimize pressure drop through the damper’s blades. This makes parallel blades the best orientation for maintaining air flow.''

			''In opposed orientation, the movement of the opposing blades can increase pressure drop while opening and closing. This can put undue strain on your HVAC system every time the damper operates. Parallel blade orientation is best for directing airflow in quick bursts.''

			''While they may affect airflow, opposed blades do serve an important role in your HVAC system. The opposed blade action can modulate airflow and provide more torque to the blades while in the closed position. Tighter seals between each blade will minimize air leakage in the process. Opposed blade orientation is best for modulating airflow at different points in the duct.''

Q: Was asked a question about Surface Treatment dropdown in the condenser tab of the ERP being "ELECTROFIN" instead of the defualt "None" and if it did anything to the weight or performance of the condenser coils. 

A: Changing the dropdown to ELECTROFIN does not change performance or weight. It actually doesn't change anything and I would recommend not changing it from the default None.
