The Tower Vortx 8 Litre Digital Dual Basket Air Fryer T17164 is the strongest all-round option in this specification-led comparison. It has two separate 4-litre baskets, eight cooking presets, Sync cooking and a listed price of £89.99 from Tower Housewares. It suits households that want to cook two foods at once without moving to one of Tower’s larger models.
| Model | Best for | Key features | Listed price |
|---|---|---|---|
| Tower Vortx 8 Litre Digital Dual Basket T17164 | All-round dual-basket cooking | Two 4-litre baskets, 2,700 W, 80–200 °C, eight presets, Sync | £89.99 |
| Tower Vortx Vizion 8 Litre Digital Dual Basket T17151 | Watching food while it cooks | Two 4-litre baskets, viewing windows, 3,040 W, nine presets | £99.99 |
| Tower 9 Litre Dual Basket Air Fryer | More dual-basket capacity | 9-litre dual-basket design | £99.99 |
| Tower 6 Litre Dual Basket Air Fryer | A smaller dual-basket option | 6-litre dual-basket design | £69.99 |
| Tower 4 Litre Digital Air Fryer | Smallest listed budget option | 4-litre digital design | £49.99 |
The specifications and listed prices come from the T17164 product page, the T17151 product page and Tower’s air fryer listings. Prices and promotional offers can change.
Choose a dual-basket Tower air fryer if you regularly want two foods ready together. The T17164 is the clearest choice when simultaneous cooking matters: its Sync function is designed to finish two different dishes at the same time. Its two baskets each hold 4 litres, giving a combined stated capacity of 8 litres.
The T17151 also has two 4-litre baskets, but adds a viewing window to each basket. This lets you monitor browning without opening the drawer. It has nine preset programmes and a higher stated power rating of 3,040 W. The difference between the two 8-litre models is therefore mainly the viewing windows, preset count and listed price.
Tower also lists 6-litre, 8.5-litre and 9-litre dual-basket models. The 6-litre model is listed at £69.99, the 8.5-litre Vortx model at £119.99 and the 9-litre model at £99.99. A dual-basket layout is useful when separate foods need different cooking times, temperatures or handling.
A 4-litre Tower air fryer is the simplest option when you want a single basket and a lower purchase price. Tower lists its 4 Litre Digital Air Fryer at £49.99 and also lists a 4.2 Litre Vortx Digital Air Fryer at the same price.
The compact format avoids the second drawer found on dual models and is suited to straightforward single-dish cooking. If you need two foods at different temperatures or want to prepare larger batches, the 6-litre or 8-litre dual-basket options provide a different layout.
Tower also lists a Vortx 7.2 Litre Digital Air Fryer, an 8.5 Litre Dual Basket model and a 9 Litre Dual Basket model. The 7.2-litre model is a single digital air fryer in Tower’s range, while the 8.5-litre and 9-litre models use two baskets. The 8-litre T17164 divides its capacity into two equal 4-litre baskets rather than one large cooking compartment.
Tesco lists the Tower AIRX 5L Digital Single Basket Air Fryer at £32 with Clubcard. The offer is stated to apply to deliveries between 20 August and 30 September 2026. It is a single-basket model with a lower listed price than the Tower Housewares models in the table.
Tesco also has product pages for the Tower Dual Layer Air Fryer 11 Litre T17190 and the Tower T17123 Vortx Colour Display 7.5L. These listings cover larger Tower air fryers, including a dual-layer design, for shoppers looking beyond the 4-litre and 5-litre single-basket formats. Tesco’s Tower range is available through its Tower air fryer listings.
Six Tower air fryer models are subject to an official UK recall because of a risk of overheating and fire. The affected model numbers are T17023, T17061BLK, T17067, T17087, T17129L and T17129. The appliances were made between January 2022 and April 2023.
The affected products were sold through retailers including Argos, B&M, Poundland, Sainsbury’s, Tesco and Tower Housewares. The GOV.UK recall notice says owners of an affected model should stop using it immediately and unplug it.
Check the model and batch number on the appliance’s rating plate. Tower uses those details in its recall process. The Tower safety recall service offers either a £60 gift card or a replacement air fryer with equivalent or better specifications for an eligible product. Models made outside the January 2022 to April 2023 period are not included in this particular recall, according to Which?.
Which? describes Tower as the lowest-performing of the three brands it compares—Tower, Ninja and Tefal—but also says that newer Tower models have achieved significantly better results. That makes the brand-level result a useful warning rather than a verdict on every current appliance.
There is no evidence that every Tower model performs as well as every Ninja model. For a buyer comparing Tower with Ninja, the practical distinction is between an official Tower specification and independent performance testing: the T17164 offers two 4-litre baskets and Sync cooking, while Which? advises judging Tower models individually because newer products have improved.
For the models covered here, the T17164 is the most straightforward choice for coordinating two dishes. The T17151 adds viewing windows, 3,040 W of stated power and nine presets. The 4-litre and 4.2-litre models are the lower-cost single-basket choices, while the 6-litre dual-basket model sits between the compact models and the larger 8-litre designs.
Tower has a broad UK range, from compact 4-litre digital models to dual-basket appliances with 9 litres of stated capacity. Its models cover different price points and formats, including single baskets, dual baskets and the dual-layer 11-litre model listed by Tesco. However, Which?’s comparison places Tower below Ninja and Tefal overall, while noting better results from newer Tower models. Tower is therefore a reasonable brand to consider, but model choice and recall status matter.
There is no evidence that everyone, or a majority of consumers, is getting rid of an air fryer. The objections highlighted in consumer material are more specific: an air fryer takes up worktop or storage space, needs cleaning, cannot replace every type of cooking and may not deliver the energy saving a user expects. Chips were the most common food prepared in an air fryer in a British Leatherhead Food Research survey, followed by breaded chicken and potatoes.
For some Tower owners, the official overheating and fire-risk recall is an additional reason to stop using a particular appliance. That issue applies to the six listed model numbers and should be handled through the recall process rather than treated as a reason to discard every Tower air fryer.
For basic use, select the food and cooking programme that matches the appliance, place the food in the basket and use the temperature and timer controls provided by that model. The T17164 has a temperature range of 80–200 °C and a 60-minute timer, while its Sync function coordinates two baskets. Follow the model-specific instructions for food quantities, cooking times, cleaning and safe operation.
Tower says instruction manuals can be downloaded from the relevant product page under Downloads or Accessories. Its support guidance is available in the Tower instruction-manual guide. Owners should complete the recall check before using any appliance whose model and batch details may match the affected list.
The T17164 is the clearest option for two foods that need to finish together because it has two separate 4-litre baskets and a Sync function. The T17151 also has two 4-litre baskets, with viewing windows and nine presets instead.
Yes. Tower lists both a 4 Litre Digital Air Fryer and a 4.2 Litre Vortx Digital Air Fryer at £49.99. These are single-basket options rather than dual-basket appliances.
