Dual-basket air fryer

Ninja Foodi Dual Zone AF300UK

Model AF300UK (also AF300) — United Kingdom

The smaller two-drawer Ninja, rated at the same 2470W as the 9.5-litre model. Specifications read from the manual.

Where to get real advice for this machine

Almost everything that changes a cooking answer is a property of the architecture rather than the badge. This is a dual-basket air fryer, and the Dual-basket air fryer page carries the cooking guidance that actually applies to it.

Each drawer works like a basket machine of its own, so a basket figure is the place to start in either one. Where your manual prints a row for each drawer, use the row for the drawer you are filling, because the two drawers are not always the same size. One manufacturer's table for a machine with a larger and a smaller drawer gives every food it covers in both a separate row for each: the quantity is always smaller for the smaller drawer, the temperature is the same in both, and the time is the same for most foods and shorter for a few. That is one table, and it is not a rule about small drawers, so do not turn it into an adjustment of your own — a figure printed for one drawer is a figure for that drawer and that quantity. What also changes is the planning: two foods with different times must be started at different moments, and the synchronise function most of these machines offer does that by delaying the shorter cook rather than by speeding it up. Total capacity is genuinely double, but each individual drawer is often slightly smaller than a comparable single-basket machine.

That is guidance for the type. On preheating, this machine’s own manual is quoted further down this page, and where the two differ the manual is the one to follow.

Does it genuinely air-fry?

Genuine air frying

Assessed against the criteria on the same basis as the AF400UK, with which it shares its architecture and its manual's description of it: two self-contained drawers, each with a separate element and fan above a perforated crisper plate that elevates the food. Fast air and air reaching every surface are met by construction.

  • Air moves fast, not just around
  • Air reaches every surface of the food
  • Recovers temperature quickly after loading
  • Fat and moisture drain away
  • Reaches genuine browning temperatures

What we know about this machine

Read from Ninja Foodi Dual Zone Air Fryer AF300UK — Instructions (PDF) (revision AF300UK_Series_30_IB_MP_Mv2_200414), retrieved on 2026-08-13.

It is rated at 2470 W, which is toward the top of the domestic range and means it recovers temperature quickly after cold food goes in. It has 2 independent drawers, so two foods can cook at different temperatures at once — which buys variety rather than volume. On preheating: comes up to temperature quickly.

The figures above are the manufacturer’s. What they mean for cooking is AirfryerHQ’s reading of them, not a measurement — nobody here has run this machine.

10 figures we could not establish

Each of these says WHY it is missing. “Not recorded by the sources consulted” means the manufacturer does not publish it in the document we read — not that nobody looked, and not that the figure does not exist.

Advertised capacity
Not recorded by the sources consulted — The manual's technical specification panel states voltage and wattage only. The retailer that published this copy titles the product 7.6L, but a retailer's product title is not a manufacturer specification and is not recorded as one.

What each setting actually does

Read from the manual. The first column is the name printed on the panel; the second is what that setting is in plain terms, so you can use advice written for somebody else’s appliance.

  • Max Crisp: Described as best for frozen foods such as French fries and chicken nuggets. The manual gives it a time and no temperature step: the time is set in 1-minute steps up to 30 minutes.
  • Air Fry: Time is set in 1-minute steps up to 1 hour. The drawer can be taken out during cooking to shake or toss the food.
  • Roast: Time is set in 1-minute steps up to 1 hour and in 5-minute steps from 1 to 4 hours. The crisper plate is optional.
  • Reheat: Time is set in 1-minute steps up to 1 hour. The crisper plate is optional.
  • Dehydrate: A default temperature appears on the display, and the manual does not print it. Time is set in 15-minute steps from 1 to 12 hours. Food goes in two layers: one under the crisper plate and one on it.
  • Bake: Time is set in 1-minute steps up to 1 hour and in 5-minute steps from 1 to 4 hours. The manual says to reduce a conventional oven recipe's temperature by 10°C.

Questions owners ask about this machine

Answered from this model’s own manual (Ninja Foodi Dual Zone Air Fryer AF300UK — Instructions) and nothing else. Where the manual does not address a question, it is not answered here from another machine’s.

What this manual calls the parts

Crisper plate
The perforated plate the food sits on.
Drawer
The part that slides out and holds everything.

Other manufacturers use different words for the same parts, and sometimes the same word for a different one. What each part is called, brand by brand.

Before the first cookWhat do I do before using it for the first time?
Take off all packaging, promotional labels and tape, then wash the drawers and crisper plates in hot, soapy water, rinse them and dry them thoroughly. The manual asks for nothing else before the first cook: it describes no empty test run.In the manual: Before First Use.
The parts, and how they go inDoes the crisper plate stay in the drawer?
It depends on the function. The steps for Air Fry and Max Crisp both begin by installing the crisper plate. For Roast, Reheat and Bake the manual marks the plate as optional. Dehydrate uses it differently: one layer of food on the drawer floor, the plate on top of that, and a second layer on the plate. The manual's reason for the plate is that it lifts food so air can circulate under and around it.In the manual: Cooking in your air fryer, steps for each function; Helpful Tips.
Opening it while it cooksWhat happens if I pull a drawer out while it is cooking?
The countdown pauses when a drawer is removed and resumes when it goes back. The manual gives two different limits for putting it back before the unit switches off: one minute in its note on pausing, and two minutes in its troubleshooting guide. Treat the shorter one as the limit. Temperature and time can both be changed at any point during cooking, per zone.In the manual: Pausing Cooking, note; Troubleshooting Guide, 'How do I pause the countdown?'; Helpful Tips.
Settings the panel does not explainWhy has the display gone dark?
The unit enters standby mode after 10 minutes with no interaction with the control panel. The troubleshooting guide gives the remedy for a blank screen: press the power button to turn it back on.In the manual: Standby mode; Troubleshooting Guide.
Oil, and dishes inside itDoes this manual say to use oil?
For fresh vegetables and potatoes it does: at least one tablespoon, with more if you want them crisper. It does not ask for oil on other foods.In the manual: Helpful Tips.
How much goes in at onceHow full can I fill a drawer?
There is no fill line and no weight. The safeguards say not to overfill, to prevent food touching the heating elements. The tips and the troubleshooting guide give the working rule: an even layer on the bottom of the drawer with no overlapping, and a shake where pieces do overlap. For space around the unit the manual asks only for adequate space above and on all sides, with no figure.In the manual: Important Safeguards, items 19 and 22; Helpful Tips; Troubleshooting Guide.

Faults the manual documents, as printed

Only what the manufacturer publishes. AirfryerHQ does not invent the meaning of an error code, and where a manual documents one undifferentiated fault state that is what appears here.

  • “E”

    The manual states only that an 'E' message on the display means the unit is not functioning properly. No breakdown by code is published.

    The manual instructs the owner to contact the manufacturer's customer service. AirfryerHQ has no further detail and will not invent any.

  • Food did not cook fully

    The manual attributes this to the drawer not being fully inserted, or to ingredients overlapping rather than lying in an even layer.

    Check the drawer is fully home, arrange food in an even layer with no overlap, and shake the drawer to toss it. Temperature and time can both be adjusted during cooking.

  • Lightweight food blows around the drawer

    The manual acknowledges that the fan will occasionally blow lightweight foods around; the example it gives is the top slice of bread on a sandwich.

    Secure the food with wooden cocktail sticks.

  • The unit is beeping

    Not a fault. The manual says a beep means the food is done cooking, or that the other zone has started cooking.

    Nothing needs doing.

Replaceable parts

Read from this machine’s own documentation. Fit is stated only for the models a manufacturer names — it is never inferred from advertised capacity.

  • Crisper plate

    Crisper plate for the Ninja AF300UK

    The perforated plate that raises food off the drawer floor so air reaches underneath. The AF300UK takes two, and they are a different part from the AF400UK's.

    You can fit this yourself: Lift out, drop in. Order by the reference above. Cooking without a crisper plate is possible and is not air frying: the food sits in the drawer floor and in its own rendered fat.

    Manufacturer reference: 4239CY300EUUK

    People replace it because: the non-stick coating has worn or is peeling; it is lost, or was missing from the box; it is cracked, warped or broken.

    Flaking coating is the end of that part's working life. Keep metal utensils and abrasives off it, which the manual requires.

    The 7.6-litre AF300UK and the 9.5-litre AF400UK use different plates with different references.

  • Drawer

    Drawer 1 for the Ninja AF300UK

    The first of the two outer drawers. The manufacturer numbers them rather than naming sides, and they are separate parts with separate references.

    You can fit this yourself: Slides out and back in; no repair involved. Order Drawer 1 by its own reference and check which of the two you need first.

    Manufacturer reference: 4237CY300EUUK

    People replace it because: the non-stick coating has worn or is peeling; it is cracked, warped or broken; it cannot be got clean any more.

    Replace rather than persevere with a drawer that no longer closes squarely or whose coating has begun to flake.

    The model identifier is on the rating label. AF300UK parts do not fit the AF400UK.

    Ninja air fryer replacement parts

  • Drawer

    Drawer 2 for the Ninja AF300UK

    The second of the two outer drawers, sold under its own reference rather than as a pair with the first.

    You can fit this yourself: Order Drawer 2 by its own reference. If you are unsure which drawer you have damaged, the manufacturer's parts store lists both and the numbering matches the manual.

    Manufacturer reference: 4238CY300EUUK

    People replace it because: the non-stick coating has worn or is peeling; it is cracked, warped or broken; it cannot be got clean any more.

    Same as Drawer 1: flaking coating or a drawer that will not seat is a replacement rather than something to work around.

    Check the rating label, and check which drawer you need.

Recall and safety status

Recall status not checked

No verified recall or safety notice is currently recorded in AirfryerHQ for this appliance. That is a statement about this catalogue and not about the product: AirfryerHQ holds a small number of checked alerts and is not a copy of the UK register. Check the authority's own register before concluding that an appliance is unaffected.

The Office for Product Safety and Standards publishes the UK register of product safety alerts, reports and recalls on GOV.UK, and Electrical Safety First operates a recall checker for electrical appliances. Registering an appliance with its manufacturer is what makes a direct notification possible.

AirfryerHQ has no recall data feed and has not checked. That is not a clean bill of health — it is an absence of checking, and it is recorded as one. Check the manufacturer’s own recall page and your national product-safety register.

About this model

A dual-basket machine one size down from the AF400UK, with the same two-independent-drawers architecture and the same Sync and Match functions. It is in the catalogue partly on its own merits and partly because reading two manuals from one manufacturer is what established which of their statements are model positions and which are company positions.
