What’s the Difference Between Ninja AF400UK and DZ400UK?

If you’re wondering what’s the difference between Ninja AF400UK and DZ400UK, here’s the reassuring answer: very little when it comes to cooking. Both are large 9.5-litre, two-drawer Ninja Dual Zone air fryers with the same six cooking programmes, SYNC and MATCH, and a 2,470W power rating. The clearest difference is the appearance: the AF400UK has the familiar black finish, while the DZ400UK has a newer-looking gun-metal grey finish.

So you don’t need to pay more for one model expecting dramatically crispier chips, extra cooking functions or more space for dinner. The better questions are which look you prefer, which retailer has the best offer and whether the product listing includes the expected accessories.

Ninja AF400UK vs DZ400UK: Quick Comparison

Ninja’s own UK listings for the AF400UK and DZ400UK show just how closely matched they are. This table draws on both models’ instruction books and the manufacturer’s UK specifications.

At a glance: these are not two different capacities or performance tiers. The DZ400UK is presented with refreshed styling; the advertised core cooking features are effectively the same.

Ninja AF400UK vs DZ400UK Difference: What Has Actually Changed?

Ninja calls the black AF400UK the Foodi MAX Dual Zone, while the DZ400UK is marketed as the MAX Dual Zone with updated dark-grey metallic trim. The product code and appearance differ, but the published capacity, power and programmes do not.

There’s an especially useful manufacturer clarification: when UK customers asked whether the DZ400UK was the same as the AF400UK, SharkNinja answered that their specifications were identical, with differences in finish or packaging. That’s a stronger reason to treat this as a model-and-styling choice than to assume a hidden cooking upgrade.

You may notice inconsistent external dimensions or product weights between retailer descriptions, or even different sections of manufacturer listings. Rather than promise a precise size advantage that isn’t consistently documented, check the current seller’s measurements and the space available on your own worktop.

What’s the Difference Between Ninja AF400UK and DZ400UK in Everyday Cooking?

Think about a typical family dinner: chicken in one drawer and chips or roast vegetables in the other. Both machines let you set different functions, temperatures and times for the two drawers, then press SYNC so your food finishes together.

If you’re making two batches of the same food, MATCH copies the first drawer’s settings to the second. Both manuals describe the same rotary START/STOP dial, separate Zone 1 and Zone 2 selection, and temperature/time controls. Removing a drawer pauses cooking, too.

So, what’s the difference between Ninja AF400UK and DZ400UK once dinner is underway? Based on the functions and controls described in their manuals, practically nothing significant. You’re choosing between two closely related 9.5L Dual Zone models, rather than a basic machine and an advanced one.

Are the AF400UK and DZ400UK Both Dual Zone Air Fryers?

Yes. They each have two independent 4.75-litre drawers, for 9.5 litres of total capacity. The big attraction is being able to cook different foods at the same time without trying to make one oven temperature suit everything.

However, those drawers remain separate. They don’t combine to make one open 9.5L cooking compartment, so an unusually long tray or joint won’t fit simply because the total capacity sounds generous.

If you’re wondering whether the layout suits you, we’ve covered whether a dual-basket air fryer is worth it, as well as Ninja air fryer sizes for a family of four.

Do the AF400UK and DZ400UK Have the Same Cooking Functions?

Yes. Both instruction manuals list the following six programmes:

• Air Fry: everyday cooking for foods such as chips, chicken and vegetables.
• Max Crisp: high-heat cooking, particularly for smaller amounts of frozen food.
• Roast: meats and vegetables.
• Reheat: warming leftovers.
• Dehydrate: drying fruit, vegetables and other suitable ingredients.
• Bake: cakes and desserts.

It’s worth clearing up a misleading comparison you may come across: both the AF400UK and DZ400UK have a fixed 240°C Max Crisp programme. Their standard Air Fry setting defaults to 200°C, but that doesn’t mean the AF400UK is restricted to a 200°C maximum. It isn’t.

Their manuals also specify up to 60 minutes for the Air Fry programme. In ordinary use, there’s no extra function or longer Air Fry timer on the DZ400UK to justify a higher price.

Is the Ninja DZ400UK Air Fryer the Same as the AF400UK Air Fryer?

For cooking purposes, they’re best regarded as equivalent models. They aren’t literally the same product code, and they may have different finishes, packaging or retailer offers. Those differences matter when ordering replacements or comparing what’s included, even though they don’t point to better cooking performance.

Check the full model code on the listing, not just the photo. You should expect the main unit, two drawers, two crisper plates and the accompanying documentation. Some retailer bundles may include promotions or additional accessories, so don’t assume every deal is directly comparable.

Neither model should be confused with the AF451UK, which has a built-in digital cooking probe. If that sounds more useful to you, read our AF400UK vs AF451UK comparison before buying. The standard AF400UK and DZ400UK instructions supplied for this comparison don’t show that Smart Cook probe feature.

Are the Drawers, Coatings and Cleaning Requirements Different?

Both come with non-stick drawers and removable crisper plates. Their manuals say the drawers and plates are dishwasher safe, although Ninja recommends hand-washing to help extend their life. The electrical main unit must never go in the dishwasher.

There’s no verified everyday cleaning advantage that would make one model the clear winner. If you’re particularly concerned about coatings, check the materials for the exact component rather than guessing from the colour of the machine. Our separate guides explain which Ninja air fryers have ceramic coating and whether Ninja air fryers are Teflon-free.

For everyday maintenance, you can also see whether Ninja air fryer drawers are dishwasher safe and why the crisper plate matters. These are more useful considerations than the different letters at the start of the model numbers.

What About Worktop Space and Ventilation?

Both are fairly substantial appliances with two drawers to pull out, so allow room at the front as well as around the ventilation areas.

One genuine difference in the printed instructions is how specific they are about clearance. The newer DZ400UK manual tells you to leave at least 15cm of space above and on all sides. The AF400UK manual asks for adequate space around the appliance but doesn’t give the same exact figure in the copy we compared. That doesn’t establish a different heat output: it means you should follow the instructions supplied with your individual machine.

Electrical Safety First’s UK air fryer advice recommends following the manufacturer’s guidance, not overfilling the drawers and checking the plug and socket for signs of damage. If you’re unsure what capacity fits your kitchen and household, our UK air fryer size guide can help.

Which Is Better, the Ninja AF400UK or the DZ400UK?

For cooking ability on paper, it’s a draw. The AF400UK is appealing if you prefer its classic black finish, already know the Foodi MAX branding or find it on offer. The DZ400UK makes sense if you like the dark-grey metallic trim or see a lower price for the updated-looking design.

If you’re comparing listings and still asking what’s the difference between Ninja AF400UK and DZ400UK, focus on the final price, the seller, delivery, returns and any extras. Their manuals don’t show the sort of upgrade that warrants paying substantially more for one over the other.

At equal prices, choose the finish you prefer. If one is noticeably cheaper from a reputable UK seller with the expected accessories and guarantee, that’s usually the more sensible buy.

Where Is the Best Place to Buy a Ninja AF400UK or DZ400UK in the UK?

Start with Ninja’s official UK website to confirm the exact current model and colour. You can then compare stock and deals at well-known UK retailers such as Argos, Currys and John Lewis. Availability and promotional prices vary, so check the full checkout price rather than assuming the first advertised discount is the best deal.

Before ordering, check four things:

• Exact model code: confirm AF400UK or DZ400UK, rather than a similarly named 7.6L or probe-equipped model.
• What’s included: two drawers, two crisper plates and the correct paperwork.
• Seller and returns: buy from an established UK retailer and check its returns arrangements.
• Guarantee: Ninja’s UK product pages advertise a two-year guarantee; check the current registration conditions for your purchase.

Electrical Safety First also advises choosing reputable electrical-product sellers and registering appliances so you can be contacted if a safety notice is issued. We’ve not linked to any shopping sites here; it’s the model and buying checks that matter most.

Frequently Asked Questions

Is the DZ400UK a Newer Version of the AF400UK?

The DZ400UK is marketed with a refreshed appearance, and the instruction booklet provided for this article is a later edition than the AF400UK booklet. But that doesn’t mean more cooking functions, a bigger capacity or a higher Max Crisp temperature. The main advertised cooking specifications match.

Can Both Models Cook Two Different Foods at the Same Time?

Yes. SYNC is designed to have two different foods finish together, even with different settings. MATCH makes it easy to cook two batches using the same time, temperature and function.

Does the DZ400UK Reach a Higher Temperature Than the AF400UK?

No. Both manuals specify a 240°C fixed Max Crisp setting. Don’t confuse the ordinary Air Fry programme’s 200°C default temperature with the maximum temperature available on the machine.

Can I Use AF400UK Accessories With the DZ400UK?

Some components may be compatible—the official DZ400UK product listing even offers a crisper plate described for the AF400. However, don’t assume every drawer, rack or spare part is interchangeable. Check the exact accessory part number and Ninja’s compatibility information before ordering.

Does Either Model Have a Built-In Cooking Probe?

No built-in Smart Cook probe system is described in the supplied manuals or standard contents for these models. If temperature-guided cooking is a priority, compare the AF451UK with its digital probe instead.

Can You Cook Chicken Safely in Either Model?

Yes, provided you cook it thoroughly and leave room for air to circulate. Ninja’s cooking charts are a starting point rather than a guarantee for every piece of food. The UK Food Standards Agency’s cooking guidance explains how to check poultry and other food is thoroughly cooked, including with a clean food thermometer.

Final Verdict: AF400UK or DZ400UK?

You don’t need to overthink this purchase. Both deliver 9.5L of Dual Zone cooking, six programmes, 2,470W of power, SYNC, MATCH and 240°C Max Crisp. The most noticeable distinction is the black AF400UK versus the gun-metal grey DZ400UK, together with whichever pricing and retail offers you find.

Choose the black AF400UK if you prefer its look or it costs less. Choose the DZ400UK if you like the refreshed finish or find a better deal. Either way, you’re getting essentially the same kind of family-sized dual-drawer cooking experience.
