This 30-inch retractable downdraft vent rises 14 inches to help filter steam from tall stockpots, and remains flush with the cooking surface when not in use. The 600 CFM Pro Motor has the power to provide effective venting for most cooktops or ranges. The vent system is reversible to help fit in the cabinet space under the vent.

Rated 4 out of 5 by from Only one of four appliances working correctly So far so good. Only one of four appliances purchased that did not need work.

Rated 1 out of 5 by from Breaks down all the time but good when it works I bought this 2 years ago - it sat for 6 months before being installed (ie. wasn't used). A year after it was installed it broke down. The vent would rise but wouldn't stay up and would drop down again so you couldn't use it. As it was technically 18 months old it was outside of the warranty period. I had a Kitchenaid repair person fix it and replaced the armature motor, cover switch and another part (# W10421277). It worked again. I used the vent occasionally for another 4-5 months and now I'm having problems again. When I press the button the unit won't rise unless I continue to depress the button. It rises about 1/3 of the way and stalls. If I then continue to re-press the button many many times it will gradually inch it's way up. I have to stop pressing the button before it reaches the top (as it will then go down) but I have to press it for long enough so that it gets to the full extension so that the fan will then work. To get the fan to go back down I then have to press and gently hold the button down as if I stop so does the vent from going down. When the unit works it works well but it's been a pain in the neck. Not to mention the back as well since each time someone comes to repair it I have to disconnect it from the underfloor vent and lift out a very heavy and very awkward and bulky unit, not to mention refitting it again which is very challenging. The unit is expensive, the parts are expensive, the labour to repair it is expensive and its really not worth it. If it worked as it should then it would be great but it just doesn't.

Rated 5 out of 5 by from Love this downdraft!! We bought this downdraft, and had it installed a few weeks ago, and really like it!! It works great, and is so much taller than our last one, so it doesn't such the burner flame out!!

Rated 5 out of 5 by from Makes our kitchen so open! Great to not have a huge vent hood. Allows us to have the cooktop on the island.

Rated 5 out of 5 by from clean look Am very happy with this downdraft. Unit was a little hard to install due to "pop-rivets" sticking out on sides. When installing in granite, you need to allow a little extra for these rivets.

Rated 1 out of 5 by from Bad product, with worse customer service The product never worked since, installation. After two visits the authorized repair company came back to me and said the critical part required to fix the problem is back ordered, without an ETA. Kitchen Aid offered only to expedite the part request. I have since provided this information, and can do nothing but wait until it is fixed. KitchenAid says that I am eligible only repair and not replacement, after initial 30 days after purchase. The unit was installed 1 month after the purchase to synchronize with the counter installation. It failed on the day of the installation, and it has been 2 months since then. For something which has not worked from day 1, and the customer is waiting for 2+ months, I am not sure this is an acceptable response. This is not an acceptable level of customer service. I had to wait for 3 times for more than 30 minutes to reach an agent.

Rated 4 out of 5 by from Downdraft fan We bought this fan over a year ago, but are just now installing it. (Kitchen remodels can take a long, LONG time) It's working beautifully, but as I said, we just installed it. I'll get back if it screws up - but I'm not expecting it to, as all of our other Kitchenaid products have worked VERY nicely. I have to add that some of the features you ask about below I really can't address at this time. But one thing I do know: it's SO much quieter than our friends' fan. I LOVE that!

Rated 4 out of 5 by from Compact and Efficient Very compact and works efficiently. A bit noisy while operating on high speed. Otherwise works well and very easy to clean the filters.
