neverest® RKI 5" Professional Backdraft Damper Inline Spring Loaded for Dryer Duct Fits Only with Metal Ducts

neverest® RKI 5" Professional Backdraft Damper Inline Spring Loaded for Dryer Duct Fits Only with Metal Ducts

Q: How much pressure does it take to open? No rating is given (in comparison, the expensive Aldes brand gives 0.04 to 0.08 in. w.g.)

Thank you for your question. Ive uploaded a graph, in metric, which hopefully you can use if your aware of your ventilators specs. It can be found under the product pictures. Otherwise you need 10 pascals to open the vent in a 4 inch duct. The spring is relatively strong on our RKI series the RK series has a weaker spring. Because the RKI has a stronger spring we suggest it be installed after the ventilator with the flaps opening away from the ventilator. Hope this helps klimapartner

Q: In a *horizontal* duct installation, is there an optimal orientation for the spring/blades? (e.g., orient spring horizontally or vertically)? Thanks.

Thank you for your questoin. If you install the damper parallel, horizontal, to the ground it doesnt matter which way the sping/blades are. If you intsall the backdraft shutter vertically you want the blades/springs perpendicular to the ground. For further questions please dont hesitate to ask. sincerely, klimapartner

Q: My vent lines are already merged below the roof, to a 90° 4" vent roof pipe cover. Will your cover work for me? My old flapper broke.

Thank you for your question. Yes our backdraft shutter will work for you as long as you have a strong enough ventilator to push it open from that distance. The springs are stronger on the RKI then our RK model. If you install, which we recomend, the shutter right behind your ventilator you will not have any problems. The joy of the RKI series is that you can order it, install it without much hassle and if it doesnt work send it back. The RK 4 inch series https://www.amazon.com/dp/B011INHF5A has a weaker spring. This would also work and you need to connect it between two ducts. sincerely team klimapartner

Q: Go a kitchen exhaust should this be installed close to the fan or closer to the exterior wall.

If your goal is keeping the cold or hot air out of the house, it should be installed near the exterior wall of house. It will attract less grease build up the further away from hood and it will be easier to service or clean if you can access it from the outside rather than opening up interior walls.
