[Used] AirJet 90cm 4 Ring Induction Hob with Extractor Black

• Two appliances, one sleek surface: The integrated DownAir extractor draws steam and odours downward directly at the hob, delivering up to 754 m³/h — no overhead hood required.

• Cupboard space back where you need it: The slim downward-extraction motor sits below the worktop in just 20 cm, reclaiming the cabinet space that a conventional hood motor would otherwise occupy.

• Made for kitchen islands: Because extraction is built into the hob itself, there's no ceiling or wall needed for a hood — giving you a completely clear sightline across an open-plan kitchen.

• Handles any pot, any size: The VarioHeating system merges two cooking zones into a single flex zone of 3,600 W per pair, so oversized pans, casserole dishes, and griddle plates heat evenly across the full base.

• Clean and safe, even when life gets busy: The touch controls are integrated flush into the glass surface — no buttons, no crevices — and a child lock keeps settings safe when little hands are nearby. A built-in timer runs up to 99 minutes, so you can step away from the hob with confidence.

If your kitchen island has always felt like it was missing something, the Klarstein AirJet 90 DownAir System might be exactly that thing. This clever unit combines a four-zone induction hob with a built-in DownAir extractor — so instead of a hood looming overhead, extraction happens right at the hob, pulling steam and cooking smells downward as you cook. The motor sits below the worktop in a profile just 20 cm deep, freeing up valuable cupboard space above.

The induction surface itself is no slouch. Four cooking zones — each rated at 1,800 W individually — can be paired using the VarioHeating system, which merges two adjacent zones into a single large flex zone of 3,600 W per pair. That means oversized pots, casserole dishes, and griddle pans fit properly and heat evenly. Hit the Booster on any individual zone and you get 2,000 W for when speed matters.

Everything is controlled through a flush touch panel set directly into the glass surface — no buttons, no raised edges, just a seamless finish that wipes clean in seconds. The hob includes pan detection, a timer that runs up to 99 minutes, and a child lock for peace of mind at the busiest moments. The extraction side handles up to 754 m³/h, runs at 58 dB on its lowest setting, and features an integrated oil collection tray and aluminium grease filter.
