How to improve the performance of galvanized air duct?

Since the galvanized air duct does not have good silencing performance when used, we need to add a muffler to the air duct, and its thermal conductivity is too large, so it has no thermal insulation performance. Therefore, we need to add an additional thermal insulation layer when using it. We also have requirements for the use environment. We should not use it in some humid environments, This often makes the galvanized air duct easy to rust due to the influence of the environment.

We must do the above work well when using galvanized air duct. Only in this way can we enjoy more ideal results, prolong the service life of products, save costs and work benefits for us.
