The Ninja MAX DZ400UK has appeared at £139 via HotUKDeals, making it one of the sharpest prices we’ve seen on a large-capacity dual-zone air fryer from Ninja. Here’s what you need to know before you spend.
The Ninja MAX DZ400UK is a 9.5-litre dual-basket air fryer, sitting at the top of Ninja’s DualZone range and positioned above the popular AF400UK in terms of capacity and maximum temperature. The “MAX” designation refers to its ability to reach 240°C, which is higher than the standard DualZone models that top out at 200°C. It comes in two colours: Black and Cyber Space.
The six cooking functions are air fry, max crisp, roast, bake, reheat, and dehydrate. The two independent 4.75-litre baskets can run simultaneously with different settings, which is the core appeal of the DualZone design. Per Ninja’s own specs, the combined 9.5L capacity is large enough to cook a whole chicken in one basket and chips in the other.
The deal flagged on 9 April 2026 via HotUKDeals put the DZ400UK at £139, available in both colourways.
At £139, this is a strong price for a 9.5L dual-zone model. For context, the standard Ninja DualZone AF400UK (also 9.5L but without the MAX 240°C function) has typically sold for £149 to £179 at major UK retailers. The MAX version commands a small premium in normal trading, usually sitting between £159 and £199.
The Ninja Foodi 6-in-1 2-Basket Air Fryer listed on Shopping.co.uk is currently priced at £262.01 via OnBuy.com, which illustrates just how much prices can vary across the range and across retailers. At £139, the DZ400UK deal represents a saving of over £120 compared to that listing, though the two products have different specs and colourways.
Competing large-capacity dual-zone fryers from other brands sit in a similar bracket. The Cosori Dual Blaze 6.4L runs around £99 to £120, though it offers less total capacity. The Tower T17088 9L dual-basket model can be found below £100, but lacks the MAX temperature ceiling and Ninja’s build quality reputation.
The £139 price was flagged via HotUKDeals on 9 April 2026 — check the source listing to confirm current availability and which retailer is carrying that price, as deal prices can move quickly once shared publicly.
For the Ninja Foodi 6-in-1 2-Basket Air Fryer (Grey/Black), we’re currently tracking one UK retailer: OnBuy.com at £262.01. That price is correct at time of writing, but we’d recommend comparing current offers on Shopping.co.uk to catch any price changes as more retailers come into stock.
If you’re flexible on the exact model, it’s worth checking Amazon UK, Currys, and Argos — all three regularly stock Ninja DualZone fryers and run promotions across the range, particularly around bank holidays and mid-season sales.
Dual-zone air fryers have become one of the most-searched kitchen appliance categories in the UK over the past two years, and Ninja holds the largest share of that market. The ability to cook two different foods at two different temperatures simultaneously is a practical upgrade for households that have outgrown a single-basket model.
The MAX temperature of 240°C is the real differentiator here. Standard air fryers at this price typically cap at 200°C, which is fine for most tasks but falls short when you want to properly crisp pizza bases, sear proteins, or replicate higher-oven temperatures. Reaching 240°C doesn’t just speed up cooking , it changes the texture results you can achieve.
At 9.5L total, this is a family-sized appliance. It takes up counter space (approximately 40cm wide per Ninja’s product dimensions), so it’s worth measuring your kitchen before ordering. The Cosori and Tower alternatives mentioned above are physically smaller if space is a constraint.
One honest caveat: at the time of writing, we don’t have hands-on review data specific to the DZ400UK’s MAX function performance versus the standard AF400UK. The price difference at £139 is small enough that the MAX version looks like the better buy on paper, but real-world temperature consistency at 240°C is worth checking in user reviews before committing.
At £139 for a 9.5L dual-zone fryer with a 240°C MAX function, this undercuts the typical retail price of the standard DualZone AF400UK and sits well below the £262.01 we’re currently tracking on the Ninja Foodi 6-in-1 via OnBuy.com.
Best place to buy: Check the HotUKDeals listing for the retailer carrying the £139 price , for ongoing price tracking across UK retailers, compare current offers on Shopping.co.uk, where we update pricing as it changes.
vs. the standard AF400UK: The MAX version adds 40°C of headroom over the standard model for what has historically been a £10 to £20 premium at most retailers , at the same £139 price point, there’s no reason to choose the non-MAX version if you can find this deal.
Our take: Buy now if you’re in the market for a large dual-zone fryer; if you only need a smaller capacity, the Cosori Dual Blaze at around £99 is the smarter spend.
What is the difference between the Ninja DZ400UK and the AF400UK?
Both are 9.5L dual-basket air fryers with six functions. The DZ400UK carries the MAX designation, meaning it reaches 240°C versus the AF400UK’s 200°C ceiling. The higher temperature is better for crisping and high-heat roasting.
Does the Ninja DZ400UK work as a single large basket?
No. The two 4.75L baskets are separate units. You can run them simultaneously with the DualZone sync or match functions, but they don’t combine into one open cooking space.
Is 9.5L large enough for a family of four?
Per Ninja’s own guidance, yes. The combined capacity handles a whole chicken plus a side dish simultaneously. For a family cooking batch meals or Sunday roasts regularly, it’s a practical size.
How does the Cyber Space colour differ from Black?
Cyber Space is a dark teal-grey finish. Both colourways share identical specs and functions. Availability of each colour may vary by retailer and deal.
