Ninja Unveils the Double Stack XL 9.5L Air Fryer (SL451): Big Capacity, Small Footprint, All-In-One Solution

As home kitchens continue to evolve into high-efficiency zones of creativity, one name is standing out by turning everyday cooking into an experience of convenience, health, and innovation: Ninja. With the launch of its latest appliance — the Ninja Double Stack XL 9.5L Air Fryer (SL451) — the beloved kitchen-tech brand is redefining what multitasking in the kitchen can look like.

Compact on your countertop, yet massive in capacity, the SL451 is designed for modern households looking for speed, flexibility, and versatility, all while promoting healthier cooking.

Double the Layers, Double the Possibilities

What makes this air fryer stand out? It’s all in the name: Double Stack. The innovative two-level cooking system offers 9.5 litres of capacity while saving 30% more space on your kitchen counter compared to traditional side-by-side dual drawers. You can now cook two full meals — mains and sides — in one go, without the need for batch cooking or multiple appliances. Or even 4 meals in one goal.

From crispy chicken wings on the top rack to roasted vegetables on the bottom tray, the Ninja SL451 ensures even cooking on both levels, thanks to its Dual Heat Zone Technology and intelligent airflow system.

7-in-1 Smart Cooking Functions

Whether you’re air frying, roasting, baking, grilling, or reheating, this appliance does it all. With seven smart cooking functions, the SL451 adapts to whatever’s on the menu:

🍗 Air Fry – Achieve crispy perfection with up to 75% less fat

🔥 Max Crisp – Super-fast results for frozen food

🥩 Roast – Juicy meats with a golden crust

🍕 Bake – From muffins to pizza

🥘 Reheat – Restore leftovers to fresh-out-the-oven quality

🌽 Dehydrate – Make your own fruit chips or jerky

🔥 Grill – Even indoor grilling, minus the smoke and not just that, you can ensure you will get the right texture and doneness that you want. Thanks to their temperature meat probe.

With pre-set programs and digital controls, even novice home cooks can turn out chef-level meals.

Designed for Urban Kitchens

Urban homeowners will appreciate the vertical stack design—a bold departure from the wide-footprint dual-drawer air fryers. The SL451 fits snugly against the wall, leaving more countertop room for prep, plating, or other appliances. Plus, its Sleek Matte Black finish and intuitive digital interface give it that polished, professional edge and it is not a kitchen appliance as is but a deco piece to the home too.

Cook Smarter, Eat Healthier

Ninja continues to champion air-fried goodness as a healthier alternative to deep frying. The SL451 lets you cook your favorite fried foods—crispy fries, golden nuggets, crunchy wings—with little to no oil, reducing overall fat content without sacrificing flavor. Families looking to cut calories or health-conscious individuals who want to meal prep smarter will find this appliance to be an invaluable kitchen partner.

Two Drawers. Endless Possibilities.

Cook two different dishes at once — with independent settings, temperatures, and times. Whether it’s air-frying satay in one drawer and air -frying your fried chicken or grilling your salmon or beef in the other, you get perfectly cooked results without flavour crossover.

Ninja’s Signature Touch: Easy to Use, Easier to Clean

From intuitive digital displays to non-stick, dishwasher-safe baskets and crisper plates, the SL451 is built for real life. Cleanup is a breeze, and switching between functions is seamless.

Need to cook a weeknight dinner in under 25 minutes? Hosting friends for game night snacks? Batch-prepping school lunches? The Ninja Double Stack XL handles it all, no sweat.
