This MrDublinGuide Expert Reviews page looks at the Ninja MAX DZ400UK’s size, cooking features, dual zone design, capacity, cleaning, customer feedback and things worth knowing before ordering.
Ninja MAX Dual Zone Digital Air Fryer Overview
The Ninja MAX DZ400UK is a large dual zone digital air fryer with two separate drawers and a total capacity of 9.5L. Each drawer has a 4.75L capacity, making it suitable for larger meals, family cooking and preparing two foods at once.
The idea behind the dual zone design is simple. Instead of cooking everything in one basket, users can cook two different foods in two different drawers using separate times, temperatures and cooking functions.
This can be useful for cooking mains and sides together, preparing food for different tastes or making a full meal without turning on the main oven.
2 Independent Cooking Zones
One of the biggest selling points of the Ninja MAX DZ400UK is its two independent cooking zones. These allow users to cook two foods, two ways, while aiming to have both ready at the same time.
For example, one drawer could be used for chicken while the other is used for chips, vegetables, fish fingers, sausages or another side dish. Different functions, cooking times and temperatures can be used in each drawer.
This is useful for busy homes where people want to prepare meals more quickly and avoid juggling several pans, trays or appliances.
Cook 2 Foods, 2 Ways
The dual drawer setup makes the air fryer more flexible than a single-basket model. It can help when cooking foods that need different temperatures or cooking times.
This feature may also be useful for families where people prefer different foods, or when one drawer is needed for frozen food and the other for fresh ingredients.
Useful for Family Meals and Batch Cooking
With 9.5L total capacity, this model is aimed at larger households or anyone who likes to cook bigger portions. It may suit family dinners, meal prep, batch cooking and weekend cooking.
For people who already use an oven regularly, the Ninja MAX DZ400UK may help reduce the need to heat a full-size oven for smaller or medium-sized meals.
6 Cooking Functions
The Ninja MAX DZ400UK includes six cooking functions: Max Crisp, Air Fry, Roast, Bake, Reheat and Dehydrate. These functions give the appliance more flexibility than a basic air fryer.
The Air Fry function can be used for chips, chicken, frozen foods and other everyday meals. Max Crisp is designed for crispier results, especially with frozen foods. Roast and Bake add more oven-style cooking options, while Reheat is useful for leftovers. Dehydrate can be used for drying foods such as fruit or snacks.
Air Fry and Max Crisp
Air Fry is one of the most commonly used functions. Ninja says the Air Fry function can cook with up to 75% less fat compared with deep-fried hand-cut French fries.
Max Crisp is designed to help frozen food cook quickly and finish with a crisp texture. This can be useful for frozen chips, breaded items, snacks and quick family meals.
Roast, Bake, Reheat and Dehydrate
The Roast and Bake functions make the appliance more versatile for foods beyond chips and frozen meals. Reheat can be useful for warming leftovers without making them soggy, while Dehydrate adds an extra option for users who want to experiment with dried snacks.
For most households, the most-used features will likely be Air Fry, Max Crisp, Roast and Reheat.
Extra-Large 9.5L Capacity
The Ninja MAX DZ400UK has a total capacity of 9.5L, split across two 4.75L drawers. According to the product information, each drawer can fit up to 1.4kg of fries or a 2kg chicken.
This makes it a much larger model than smaller air fryers and may suit families, larger appetites or people who like cooking in bigger batches.
However, buyers should remember that this is a large appliance, so it will need proper worktop or storage space.
Drawer Size and Cooking Space
Each drawer is designed to hold a generous amount of food. The benefit of this is that users can cook more at once, which may save time compared with smaller basket air fryers.
The downside is that the appliance itself is quite large. Customers should check the dimensions before ordering to make sure it fits comfortably in their kitchen.
Dimensions and Weight
The Ninja MAX DZ400UK measures approximately H: 32.5cm x W: 41.5cm x D: 27cm and weighs around 8.8kg.
Because of its size and weight, it may be best kept on a kitchen worktop rather than being moved in and out of cupboards every day.
Energy Saving and Faster Cooking Claims
Ninja says this model can help save up to 65% on an oven energy bill, based on testing and calculations using the recommended cook time for sausages with the air fry function compared with conventional ovens.
The product information also says it can cook up to 75% faster than fan ovens, based on testing against fish fingers and sausages, including preheat.
These claims may be useful for buyers who want to reduce oven use, but real savings will depend on what is cooked, how often the appliance is used, energy prices and whether the air fryer replaces the oven for regular meals.
Up to 75% Less Fat Claim
Ninja says the Air Fry function can cook with up to 75% less fat compared with deep-fried hand-cut French fries. This makes the appliance appealing to people who want crispy-style food with little to no added oil.
This does not automatically make every meal healthy, but it can reduce the need for deep frying.
Energy Savings May Depend on Use
Although the energy-saving claim is attractive, buyers should be realistic. The air fryer may be more efficient than heating a full-size oven for smaller meals, but savings depend on how often it is used and what it replaces.
For large households already using the oven heavily, the benefit may be different compared with someone cooking smaller meals regularly.
Cleaning and Included Accessories
The Ninja MAX DZ400UK includes two non-stick 4.75L drawers, two crisper plates and a chef-created recipe guide. The drawers and crisper plates are dishwasher safe, which can make cleaning easier after cooking.
The non-stick coating is useful for reducing food sticking, although users should still follow care instructions to protect the coating over time.
Like most air fryers, cleaning can still take effort depending on what has been cooked. Greasy foods, marinades and liners may affect how easy clean-up feels.
Dishwasher-Safe Drawers
Dishwasher-safe drawers are a useful feature for busy kitchens. They can save time compared with hand-washing everything after each use.
However, some users may still prefer hand-washing to help protect the non-stick finish for longer

Customer Feedback on the Ninja MAX DZ400UK
The customer review information provided is limited, with a 3.8 out of 5 star rating from 4 global ratings at the time of the supplied product details. Because this is a small review sample, buyers should read the latest Amazon reviews before making a decision.
Feedback is mixed. One customer says the machine is fine but very large, and felt that it did not add enough benefit compared with other equipment they already had. They also felt cleaning was more work than an oven tray and questioned how long energy savings would take to balance against the cost.
Another customer was more positive, describing it as a giant replacement for an existing Ninja and saying the dual zone feature is excellent while they continue experimenting with the full range of features.
Positive Points Customers Mention
The main positive points include the large capacity, dual zone cooking and attractive Gun Metal Grey finish. Buyers who already like Ninja appliances may appreciate the familiar setup and larger cooking space.
The dual zone feature is likely to be the biggest advantage for households that regularly cook two foods at once.
Things to Note Before Ordering
The biggest point to note is size. This is a large appliance and may not suit smaller kitchens or buyers with limited counter space.
Buyers should also consider whether they will use both drawers often enough to justify the size and cost. For some households, a smaller air fryer may be more practical. For larger families, the 9.5L capacity may be a major benefit.
Best For Larger Homes and Dual Cooking
The Ninja MAX DZ400UK is best suited to larger homes, families, batch cooking, meal prep and people who want to cook two foods at once.
It may also suit buyers who already use an air fryer regularly and want to upgrade to a larger dual zone model.
