Review on Klimapartner RKI Backdraft Damper Inline by Brandon Show

Good product from the start, but many products are good when new, right? The value of the rating lies in the performance and durability of the product after the box has been opened. The questions are, is the product suitable for the intended use and how long will it last? This product is listed as "Dryer Check Valve", other applications further down the list. OK, here's the problem. It's pretty easy. Question 1: What happens to bare metal when exposed to water? You guessed it, Rust. The spring in this damper is not galvanized, but even better made of stainless steel, no. It's just bare metal. Question 2: What happens when a dryer designed to remove moist air comes into contact with bare metal? yes rust Rust that adheres to the spring and renders the shock absorber unusable. How long will it take you ask? Well, how often does moisture come into contact with bare metal? I'm not just talking about when to use ventilation. i live in the south We have too high humidity for 5-6 months of the year. This is 24 hours a day, 7 days a week, bare metal is exposed to moisture. How many states are in the wet south? Pretty much. How fast does metal rust here? Really damn fast. How do you define value? If you buy this inexpensive product, congratulate yourself on your savings, you can grease the spring heavily or coat it with lanolin spray or some other anti-rust agent. or at least prolong life as much as possible. Get ready for scheduled inspections (who has time for that?!?). Personally, I am an advocate of the "everything is ready" principle. This check valve is manufactured by a company that did not design the product exactly for its intended purpose. A simple stainless steel spring would make this product durable. Rust protection in wet environment. Unfortunately a simple solution.
