Induction Cooktops With Downdraft: Sizes, Cutouts and Ducting

If you want an induction cooktop with the ventilation built in, there are only a handful of current models, and the fit details matter more than the brand. The 30-inch options are the JennAir JIDT730SBL, the KitchenAid KCID930SBL and the Elica NikolaTesla Flux 30-inch (ENF430BL). The JennAir lists a cutout almost identical to the radiant downdraft cooktops it sits beside in the lineup, which makes it the easiest swap into an existing 30-inch opening. The Elica has the strongest published fan (600 CFM), but its unit is deeper and taller.

This page puts the numbers most listings skip in one place: the cutout (the hole in your counter), the unit’s overall size, how much height the unit takes below the counter, how the vent is ducted, and what electrical supply it needs. If you searched “downdraft induction cooktop”, “induction cooktop with downdraft vent” or “induction range with downdraft”, note that the current downdraft induction models we found are cooktops, not ranges.

One more thing before you shop. Downdraft is a compromise, and induction plus downdraft is uncommon for reasons explained further down. If you can install an overhead hood, it will almost always capture better.

Quick comparison: induction cooktops with built-in downdraft

All are 4-zone induction cooktops with the fan built into the cooktop body. Sizes are in inches. “Cutout” is the opening to cut in the counter; “unit” is the overall size of the cooktop as listed.

Two patterns stand out. First, the JennAir units are almost 31 inches wide but need only about 28.8 inches cut in the counter, because the cooktop hangs on a lip. Second, the 36-inch Fisher & Paykel needs a cutout only 31.75 inches wide. Do not assume cutout width equals the nameplate size. Minimum cabinet depth or clearance below the unit was not published in any listing we could read, so that has to come from the installation guide.

How we researched this

We did not test any of these cooktops. This page compares published specs from Elica’s US site, an authorized retailer’s spec listings that reproduce manufacturer data (Abt), Elica installation manuals, and Whirlpool Corporation’s own announcement of its induction downdraft line. The JennAir and KitchenAid manufacturer pages would not load for us, so those numbers come from the retailer listing and should be checked against the installation guide before you cut anything. Where a figure was not published or we could not confirm it, the table says so.

The 30-inch models

JennAir JIDT730SBL

Best for: replacing an existing 30-inch downdraft cooktop with the least counter work.

• Cutout 28.84 x 21.16 in; unit 30.88 x 22.06 in; 7.88 in tall as listed
• 365 CFM extraction, 42 dBA at the lowest setting (as listed)
• Four zones: two 9 x 9 in at 3,000W each, one 8 in at 3,000W and one 7 in at 2,100W
• 240V, 40A; 2-year limited warranty as listed by the retailer

What to watch: the fan is weaker than Elica’s, and the listing does not say whether it can be ducted or only recirculated. Confirm that in the installation guide.

Check price and stock at Abt or another authorized JennAir dealer. Amazon does not list this model.

KitchenAid KCID930SBL

Best for: buyers who want a clearly stated duct-free option and a lower list price than the JennAir.

• Unit 30.86 x 22.05 in, 7.83 in tall; the listing does not give a separate cutout, so get it from the installation guide
• Ducted, or duct-free with optional charcoal filters
• Four zones, 1,400-2,300W standard and up to 3,000W with Power Boost; 240V, 40A
• Dishwasher-safe grease filter

What to watch: CFM is not on the listing. Whirlpool says the JennAir and KitchenAid induction downdraft models use technology developed with BORA, so the two are probably similar, but that is an inference, not something either brand states about this pair.

Check price and stock at Abt or another authorized KitchenAid dealer. Amazon does not list this model.

Elica NikolaTesla Flux 30-inch (ENF430BL)

Best for: people who prioritize fan power and can spare the cabinet space for a taller, deeper unit.

• Unit 30.31 x 22.56 x 10.19 in; 600 CFM, four speeds, 1.8-6.8 sones (Elica lists these for the Flux family)
• Duct transition in the box: rectangular 10 x 3 1/4 in or round 6 in; recirculating needs an optional kit and carbon filters
• Four zones with bridge; 220-240V, 40A; 3-year parts and labor as listed by the retailer

What to watch: the 10.19 in height is about 2.3 in more than the JennAir, so check the cabinet below, and the cutout was not published on the pages we could read. Ask Elica or the dealer for the installation guide first.

Check price and stock through Elica and its dealers.

If you are replacing a radiant electric downdraft cooktop

Most 30-inch downdraft swaps are radiant or coil to something else. These current models list very similar cutouts:

Notice the depth. The GE lists a cutout 20.63 in deep; the JennAir and KitchenAid list about 21.1 in. That extra half inch is small, but in granite it means re-cutting, not just dropping in. The width is the same to within 0.04 in.

Why downdraft is less effective than an overhead hood

• It works against physics. Hot steam and smoke rise. A hood sits where they are going. A downdraft has to pull a rising plume back down, and it has a short reach.
• The opening is small and low. Capture depends on how close the vent is to the source. Tall pots and rear burners put the plume behind or above the vent, so the fan pulls in room air instead.
• The duct run is awkward. Air has to go down, then usually sideways through the cabinet and out, and bends and length cut real airflow below the rated CFM.
• Ratings are best case. The CFM you see is a fan rating. The manufacturers we read do not publish capture efficiency.

A raised or telescoping vent helps because it sits closer to the pan, which is one reason the Elica units are tall.

Why induction plus downdraft is rarer than electric coil plus downdraft

Whirlpool’s own 2024 announcement described a “largely unmet consumer demand” for induction downdraft, and it took a partnership with a European maker (BORA) to bring the technology to JennAir and KitchenAid. The manufacturers do not spell out why it is hard, so treat what follows as engineering reasoning, not a quoted fact.

An induction cooktop already needs room under the glass for coils, power electronics and cooling airflow. A downdraft needs a blower, filters and a duct path in that same space. Radiant and coil elements are simple heaters with nothing to keep cool, so a downdraft fits around them more easily. That is consistent with the listed heights: the induction models run 7.8 to 10.2 in, compared with about 3.6 in for the radiant JennAir and KitchenAid (as listed by the retailer).

Induction also works only with magnetic cookware. If you are shopping for pans as well, see our induction cookware guide.

Buying guide: what to check before you buy

1. Measure your existing cutout, not the cooktop. Width, depth and corner radius. Compare them with the manufacturer’s installation guide, not the retailer listing.
2. Check the cabinet below. Downdraft units and ducting need clear space beneath the counter. Listed unit heights run from about 3.6 to 10.2 in. Drawers and shelves under the cooktop often have to go.
3. Decide ducted or recirculating early. Ducted is stronger. Recirculating uses charcoal filters that need replacing. Elica and Bertazzoni say their units can be converted, and Elica’s needs a purchased kit.
4. Confirm the circuit. The listings above call for 240V and 34 to 40A. Bertazzoni and Fisher & Paykel do not include a power cord.
5. Check the counter thickness. An Elica manual, for example, says the unit is designed for a worktop 2 to 6 cm thick (about 0.8 to 2.4 in).
6. Consider the alternatives. A standard 30-inch built-in induction cooktop plus a hood usually captures better, and a portable induction cooktop is a cheap way to try induction first.

FAQs

Is there a “Tesla 32 inch” downdraft induction cooktop?

The likely match is the Elica NikolaTesla One ENT432BL, named after the inventor Nikola Tesla, not the car company. It is a 32 in induction cooktop with a built-in fan; the listing gives 4 fan speeds from 160 to 400 CFM. Its unit size is 32 1/16 x 20 1/16 x 8 1/4 in. One retailer lists it as discontinued, and it is not among the four NikolaTesla downdraft models on Elica’s US site today (Invert, Invert Scratch-Proof, Flux and Switch). Contact Elica or a dealer before buying.

Will a 32 inch downdraft cooktop fit a 30 inch cutout in granite?

Do not assume so. The retailer listing for the ENT432BL shows a cutout of 80.7 x 49.2 cm, about 31.8 x 19.4 in (that figure may be a metric spec). A 30 in downdraft such as the GE Profile PP9830DRBB lists a cutout of 28.88 x 20.63 in. Moving to the Elica means about 2.9 in more width and about 1.2 in less depth. Extra width means cutting the granite, and probably the cabinet, because a 30 in base cabinet is only 30 in wide outside. Less depth is a separate problem: the Elica is only about 20 in deep overall, so an existing 20.63 in hole would leave part of the opening uncovered. Your old GE may have different numbers, so measure it.

How do I check cutout versus unit size?

Get the installation guide for the exact model number (a PDF from the maker’s site). Use the “cutout” figure, not the nameplate size. Measure your existing opening at both ends of each side. Then check that the unit’s overall width and depth cover the edges of the hole, and check the minimum distances to the wall and cabinets in the manual. Another reader was told to contact the manufacturer before buying, which is sound advice; ask them to confirm the cutout for your exact model.

Which current models are designed to fit a standard 30 inch cutout?

The closest matches list cutouts near 28.9 x 21.1 in: the JennAir JIDT730SBL (induction) and the radiant JennAir JED3430GB and KitchenAid KCED600GBL. The GE Profile PP9830DRBB lists 28.88 x 20.63 in. None is guaranteed to fit an older opening without touching the granite; depth is the usual issue.

Can I use a downdraft induction cooktop without ducting?

On several models, yes. KitchenAid, Elica and Bertazzoni all say their units can recirculate through charcoal or carbon filters. Recirculating removes grease and some odor but does not vent moisture or heat outdoors.

Are there downdraft induction ranges?

We did not find one from the makers covered here. Current downdraft induction options are cooktops.

Do Bosch, Thermador, Miele, GE or Samsung make one?

We could not confirm a current US model from any of them. Their sites did not load for us and none appeared in the retailer’s downdraft category. Check the maker’s site before buying.

Bottom line

If you have a 30 in radiant downdraft, the JennAir JIDT730SBL is the smallest change, though depth may still need work. If you want stronger extraction and can spare the cabinet space, look at the Elica Flux. Whichever you choose, get the installation guide first.
