## Description

The manual volume damper is used for air volume regulation in an air ventilation system, widely used in HVAC industry. With that installed in your HVAC systems, you can easily control the air flow rate or close off an air duct if needed, to some extent, it will increase the energy efficiency of your system. SpecificationColor: SilverMaterial: Galvanized IronOuter Diameter of Interface: 197 mm / 7.76 inchOverall Size: 197 x 1 mm / 7.76 x 0.04 inch (L*T)Packing List: 1 x Duct Manual Volume DamperAdvantage1. Made of durable Galvanized Iron, which has high hardness and high temperature resistance, not easy to deform and corrosion, moisture-proof and fade resistant, can be used for a long time;2. The side is designed with a rotary handle, which can adjust the air volume from multiple angles and is easy to operate;3. The interface is smooth and flat, easy to disassemble and install. Silicone rubber ring design can prevent the air duct valve from leaking when it is closed.InstructionEasy to install, just simply slide the volume damper into the pipe you are attaching to, and fix with pipe clamp and tape.NOTE: Please confirm the outer diameter of the volume damper before placing an order.

Review: This assembly is made with relatively heavy tubing. The damper has polymer edge seals, so it can close almost hermetically. The damper blade bearings are superior to those in usual duct dampers. The damper handle is made of stamped sheet metal with sharp edges, so it is advisable to wrap it with duct tape or similar. A potential difficulty is that the diameter of both ends is somewhat smaller than U.S. standard 8". It will fit snugly inside the crimped male end of U.S. duct, but it will have a significant gap inside the plain female end of U.S. duct. Shoving the raised collar of the damper assembly into the female end of the duct reduces the gap. Screws and duct tape should be used at both ends.
Review: The handle could be 1 or 2 inches higher (away from the body) so that the duct insulation can be placed under the handle instead of over it. After I wrapped it up in insulation the handle was no longer visible. If I want to change the opening percentage, I'll have to tear back the insulation for the adjustment. That's the only change I would make. I worked perfectly. I cut it into my 8 inch line and was able to adjust the flow.

### ⭐⭐⭐ Review
*by J***. on 30 August 2024*

This product is very heavy duty and looks like it will outlast my hvac system. I purchased the 8” one. It doesn’t fit tightly into 8” duct work purchased from a hvac supplier. This makes it difficult to connect the ducts together. You will definitely need to seal the joints because there are obvious gaps between the two parts.
