Space-Saving Vertical Design – 25% Slimmer*
With two drawers arranged vertically, the SL300UK is 25% slimmer* than traditional side-by-side dual air fryers — without sacrificing capacity. Each 3.8L drawer fits a 1.2kg roast chicken, ideal for up to 6 people.
2 Independent Drawers With SYNC
Mix and match functions, times and temperatures in both drawers — the SYNC feature ensures everything finishes at the same time. Perfect for mains + sides, picky eaters, or cooking different foods simultaneously. Cooking for one? Simply use a single drawer.
Six Versatile Cooking Functions
Choose from Ninja’s 6 easy presets:
• Air Fry – Up to 75% less fat****
• Max Crisp – Cook frozen foods at 240°C
• Roast – Meats, vegetables & tray meals
• Bake – Desserts, pastries, bread
• Dehydrate – Dried fruit, jerky, herbs
• Reheat – Revives leftovers perfectly
Designed for Convenience
Non-stick drawers, crisper plates, and racks are dishwasher safe. A side-mounted digital control panel provides easy access, while automatic shut-off prevents overcooking. Includes a chef-crafted recipe guide to help you get started.
Description
The Ninja Double Stack 2-Drawer Air Fryer SL300UK delivers exceptional versatility with a compact, vertical form factor designed to save valuable countertop space. A perfect choice for smaller kitchens, families, and those who want the power of a dual air fryer without the bulk, this model offers two individually controlled cooking drawers stacked top to bottom.
Each drawer features Double Stack Air Fry Technology capable of cooking on two tiers simultaneously — giving you four total cooking levels. With dual heating elements and rear-mounted fans in each drawer, you’ll enjoy even heat circulation and consistently crispy textures across every rack.
Whether you’re preparing a full meal — like chicken thighs with asparagus — or hosting with party foods distributed across four levels, the SL300UK adapts effortlessly. Use SYNC to align finishing times for mains and sides, or MATCH to copy settings between drawers when cooking larger batches.
Choose from six cooking functions including Air Fry, Max Crisp, Roast, Bake, Dehydrate and Reheat. From perfectly crisp chips to frozen-to-crispy chicken in minutes, fluffy baked goods, or dehydrated snacks, the SL300UK replaces multiple appliances.
Cleanup is simple thanks to dishwasher-safe components. With a sleek black exterior and Ninja’s 2-year guarantee (upon registration), this air fryer is built for everyday convenience, performance and reliability.
