Best Pressure Cooker Air Fryer Combos in Australia

If you specifically want pressure cooking and air frying in one appliance, the useful shortlist is much smaller than the broader multicooker market. The decision is mostly base-pot capacity, vessel material and whether you want one lid or two.

Start here: decide whether you need a combo at all

A pressure-cooker/air-fryer combination makes sense when the household repeatedly wants to pressure cook first and finish with dry heat, or when combining two appliances meaningfully reduces transfers, storage or bench clutter.

It makes less sense when you already own an air fryer you plan to keep and are happy moving food between appliances. In that situation, a focused pressure cooker can be simpler, cheaper and easier to understand because you are not paying for another crisping system.

Before comparing Duo Crisp, OP350 and OL650, decide whether integrated crisping solves a real weekly problem.

What should you decide first?

The first decision is the lid workflow.

Instant Pot Duo Crisp 8L and Ninja Foodi OP350ANZ use separate pressure and crisping lids. One lid is fitted while the other is stored.

Ninja Foodi SmartLid OL650 puts pressure cooking, Air Fry and SteamCrisp beneath one integrated lid. That removes the physical lid swap but does not make the appliance itself simple; the broader mode system still takes more learning than a focused pressure cooker.

If storing and changing a second lid would annoy you repeatedly, OL650 has a structural advantage. If storage is easy and lid swapping is occasional, keep all three in the comparison.

Which type fits you?

8L stainless two-lid: Instant Pot Duo Crisp

Choose Duo Crisp when 8L pressure-pot headroom and stainless steel both matter and the household still wants built-in air frying.

It is the largest base pot in this three-product shortlist. Its trade-off is the two-lid architecture: pressure cooking and air frying use separate lids.

This is the strongest fit for larger recurring pressure batches when a stainless main vessel is also a firm preference.

6L ceramic two-lid: Ninja Foodi 11-in-1 Multi Cooker 6L

Choose OP350 when 6L is enough and the TenderCrisp pressure-then-crisp workflow is useful.

Its main pot is ceramic coated rather than stainless steel, and it also requires separate pressure and crisping lids. The smaller base pot can be an advantage when you do not need 7.5L or 8L and would rather avoid buying unused batch headroom.

OP350 is not automatically obsolete because OL650 is newer. If 6L fits and the second lid is easy to store, the older architecture can still match the household perfectly well.

7.5L ceramic one-lid: Ninja Foodi SmartLid 14-in-1 7.5L Multi Cooker

Choose OL650 when one-lid pressure + crisp is the ownership improvement you care about and 7.5L covers the recurring batch size.

SteamCrisp gives it another cooking path, but that feature should matter only if steam-assisted crisping fits meals you actually cook. It is not a generic performance bonus.

The OL650's strongest case is not that it has more features. It is that it integrates pressure and dry-heat cooking without asking you to store and swap a second lid.

Decision factors that actually change the choice

Pressure-pot capacity

The verified nominal base pots are:

• Instant Pot Duo Crisp: 8L
• Ninja OL650: 7.5L
• Ninja OP350: 6L

Treat these litres as a constraint test rather than a quality score. If 6L handles your normal batches, more capacity may add appliance size without changing the meal. If 6L repeatedly forces a second batch, 7.5L or 8L becomes meaningful.

Vessel material

Duo Crisp uses a 304-grade stainless-steel inner pot. OP350 and OL650 use ceramic-coated cooking vessels.

If stainless steel is non-negotiable, Duo Crisp is the only clean fit within this trio. If you prefer a coated pot for easy release, the Ninja options remain more aligned.

Do not infer better cooking performance, safety or durability from material alone. Treat it as a hard ownership preference when it genuinely is one.

Lid storage and changeover

Two-lid systems ask you to find a storage home for the unused lid and switch it when the cooking stage changes.

One-lid integration removes that step, but it is only valuable if the pressure-to-crisp transition happens often enough for you to notice. A shopper who uses air frying once a month may be paying for integration that rarely changes the routine.

SteamCrisp

SteamCrisp is an OL650-specific capability in this shortlist. Give it weight when steam-assisted crisping belongs in the meals you actually cook.

Do not use it as a generic point for Ninja simply because it is absent from the other products.

What matters less than you might think

Total function count should not choose the combo. Most households will repeatedly use only a subset of modes.

The half-litre gap between 8L Duo Crisp and 7.5L OL650 is also easy to overstate. Lid workflow and vessel material can matter more day to day than that modest capacity difference.

Brand age is another weak shortcut. OP350 should not be rejected merely because OL650 is the newer Ninja platform; the older model can still be the better fit when 6L and two lids are acceptable.

What specifications actually matter?

For a pressure-and-crisp combo, focus on:

• the main pressure-pot capacity;
• pressure cooking capability;
• air-fry/crisp capability;
• one integrated lid versus separate lids;
• main pot material;
• external dimensions when bench space is tight.

Do not add the crisping basket volume to the pressure-pot volume to create a larger synthetic capacity. The base pressure pot is the useful like-for-like number for batch-size decisions.

Wattage and preset totals are supporting specifications, not proof that one model cooks better.

Common buying mistakes

The first mistake is buying a combo when you already have a good air fryer and do not actually want to retire it. Integration only helps when it changes the workflow.

The second is buying the largest capacity “just in case”. Larger is useful when your recurring meals need it, not because a bigger number looks safer.

The third is ignoring the second lid until the appliance is home. For Duo Crisp and OP350, lid storage is part of the product architecture and should be planned before purchase.

The fourth is treating OL650 as automatically superior because it is one-lid. The integration is valuable, but stainless-steel buyers or households that genuinely need 8L can still have stronger reasons to choose Duo Crisp.

Where should you go next?

Use this short decision map:

• 8L pressure capacity + stainless steel + built-in crisping → Instant Pot Duo Crisp 8L.
• 6L is enough + two-lid TenderCrisp is acceptable → Ninja Foodi OP350ANZ.
• 7.5L + one-lid pressure/crisp integration → Ninja Foodi SmartLid OL650.
• Already own an air fryer and do not need another crisping system → compare focused pressure cookers instead.

Read the individual Verdicts when one architecture looks right, then use the direct Comparisons to settle the final switch:

• Duo Crisp vs OL650
• Duo Crisp vs OP350
• OP350 vs OL650

There is no universal best combo. Choose the architecture that removes a recurring cooking problem, then let capacity and vessel material finish the decision.
