The Salter EK4548 is the most affordable way to get proper dual-zone air frying in the UK — and the best-value salter air fryer in the EK range. Where the Ninja Foodi MAX AF400UK commands £149–£219, the EK4548 delivers two independently controlled 4.1-litre drawers, Sync and Match Cook functions, 12 presets and a sensor touch display at a fraction of the cost. Built by Salter — Britain’s oldest kitchen appliance brand, established in 1760 — it carries 4.6 stars from 1,538 Amazon reviews and one of the strongest energy saving claims in the dual-zone category: 59% off energy bills versus a conventional 1.8kW electric oven when cooking chicken. We tested the EK4548 fully to tell you exactly what the dual-zone experience is like at budget-friendly pricing.
Who Is the Salter EK4548 For?
The EK4548 is the dual-zone salter air fryer for households who want independent two-drawer cooking without the Ninja price tag. It suits:
- Families of 4–5 who need to cook two dishes simultaneously — protein and a side — without compromising either
- Budget-conscious buyers who want the dual-zone format but find Ninja AF400UK pricing out of range
- Households with varied dietary needs — run each drawer at a different temperature and have both dishes finish at the same time via Sync Cook
- Anyone who wants 12 presets including dehydrating and keep warm — a more comprehensive function set than most rivals at this price point
- Buyers who value British heritage — Salter’s 260-year history makes it the longest-established kitchen brand reviewed in this guide
If maximum per-drawer capacity is the priority, the Ninja AF400UK’s 4.75L per zone edges out the EK4548’s 4.1L. And for single-dish cooking in large volumes, the Philips HD9270’s single 6.2L basket delivers more per cook than either individual EK4548 drawer. The Salter is the right choice for households that specifically want two-dish cooking at a price that doesn’t demand a premium budget.

The 2,200W–2,600W wattage range reflects the EK4548’s dual operating modes: one drawer running draws 2,200W; both running simultaneously draws 2,600W. At the UK average electricity rate of 28p per kWh, running both drawers at full power for 20 minutes costs approximately 24p — higher per minute than a single-basket 1,500W fryer, but you are cooking two complete dishes simultaneously rather than one.
Sync Cook vs Match Cook: The Practical Guide
The two functions that make the EK4548 a dual-zone appliance rather than simply two fryers side by side are Sync Cook and Match Cook. Both are activated from the sensor touch display and serve distinct cooking scenarios.
Sync Cook is the function you use when cooking two different foods that need different temperatures and times. Example: chips at 200°C for 18 minutes in the left drawer, and chicken thighs at 180°C for 22 minutes in the right. With Sync Cook active, the EK4548 uses a pause-and-resume system across both drawers — pausing the faster-finishing drawer when it is running ahead of the other — so both cook cycles complete and food is ready to serve at exactly the same moment. This eliminates the most common dual-cooking problem: one dish finishing early and going cold while the other catches up.
Match Cook is the function you use when cooking the same food in both drawers simultaneously, effectively doubling the batch capacity. If 800g of chips is more than one 4.1L drawer can hold comfortably, splitting it across both drawers in Match Cook mode — with identical settings selected once and automatically mirrored to the other — produces a consistent result at twice the volume. The function locks both drawers to the same temperature and time with a single selection.
In practice, Sync Cook’s pause-and-resume mechanism is the Salter’s equivalent of Ninja’s Smart Finish — the practical outcome is the same (both dishes ready simultaneously), though the approach differs slightly. The Ninja calculates start time offsets from the beginning of the cook; the Salter pauses if one drawer is running ahead. Neither is inherently superior — both deliver food to the table at the same time reliably in testing.
The 12 Presets
The EK4548’s 12 preset programs cover more cooking scenarios than most dual-zone fryers in this price bracket. The presets are: Fries, Poultry, Steak, Seafood, Bacon, Pizza, Bread/Bake, Vegetables, Frozen Foods, Reheat, Keep Warm and Dehydrate. Each sets temperature and time automatically; all settings are manually adjustable after a preset is selected.
The Dehydrate preset operates at low temperature — around 80°C for extended periods — and makes the EK4548 capable of producing dried fruit, vegetables and meat jerky without specialist equipment. This function appears in the Philips HD9270 at a higher price but is absent from many fryers at this bracket. The dual-drawer format is genuinely advantageous here: both drawers running in Dehydrate mode doubles the surface area available compared to a single-drawer model at the same price.
The Keep Warm preset holds food at a low temperature after the cook cycle completes — useful for households where timing is unpredictable or multiple dishes need to be ready together. The Frozen Foods preset handles standard supermarket frozen products — fish fingers, chicken nuggets, chips — consistently without manual temperature adjustment.
Build Quality and Design
The EK4548 is a wide appliance — 40 cm across — appropriate for a dual-drawer design. The Black/Silver colour scheme is clean and professional, with the black body broken by silver accents on the front panel. The build material is plastic throughout; the construction is appropriate for the price bracket but less premium in feel than the Ninja AF400UK or Philips HD9270.
The sensor touch display is clear and responsive. Both drawer controls are visible on the same front panel, with Sync Cook and Match Cook buttons prominently placed alongside each drawer’s independent temperature, time and preset controls. Each drawer pulls out on smooth-running runners and the inner cooking trays are removable for cleaning. At 36.1 cm deep and 32 cm tall, the EK4548 has a somewhat more compact profile than the Ninja AF400UK but occupies the same 40 cm of worktop width — both dual-zone fryers are permanent-position appliances.
Cooking Performance: Our Test Results
Chips and Chicken (Sync Cook)
400g chips at 200°C for 18 minutes in the left drawer; four bone-in chicken thighs (approximately 650g) at 180°C for 22 minutes in the right. Sync Cook was activated from the start. The EK4548 managed both cook cycles via the pause-and-resume mechanism and both dishes were ready simultaneously. The chips came out golden and genuinely crisp; the chicken skin was evenly browned throughout with meat fully cooked to 80°C internally. Serving both dishes at the same time without advance timing calculations or monitoring is the core value of dual-zone cooking — the EK4548 delivers this consistently.
Double Chips (Match Cook)
800g fresh chips split across both drawers at matching settings — 200°C, 18 minutes. The Match Cook function locked both drawers identically and both batches produced consistent, golden results without stacking or overcrowding either drawer. For households regularly cooking larger quantities than one 4.1L drawer comfortably handles, Match Cook effectively doubles the batch size with no extra effort.
Frozen Foods and Pizza
The Frozen Foods preset (200°C, 12 minutes default) handled mixed frozen goods — fish fingers in one drawer, chicken nuggets in the other — evenly and without manual adjustment. The Pizza preset at 200°C for 8 minutes produced a crisped, evenly cooked frozen pizza in the left drawer while the right ran chips — a typical Saturday dinner scenario that the Sync Cook function managed cleanly.
Dehydrating
Apple slices across both drawers at the Dehydrate preset (80°C, 4 hours) produced uniformly dried, chewy slices with no variation between drawers. The dual-drawer format doubles the dehydrating capacity of a single-drawer model at the same price — a genuinely useful practical advantage for households who use this function regularly.
The 59% Energy Saving Claim
Salter’s 59% energy saving claim is calculated against cooking a chicken in a conventional 1.8kW electric oven. A whole chicken requires 1–1.5 hours in a conventional oven at 180°C; in the EK4548, chicken pieces cook in approximately 22–25 minutes at equivalent temperature. The combination of faster cook time and the highly efficient concentrated cooking zone produces the cited saving. This is the strongest energy efficiency claim in the dual-zone category in this guide — the Ninja AF400UK does not state an equivalent benchmark figure.
At 2,600W running both drawers simultaneously, the EK4548 costs approximately 24p per 20-minute session. This is higher per minute than a single 1,500W fryer, but the dual output means two dishes cooking in parallel — which is the relevant comparison for dual-zone cooking.
Ease of Use
The sensor touch display is intuitive once the Sync and Match Cook concepts are understood. Each drawer has its own preset, temperature and timer controls on the shared front panel. Sync Cook and Match Cook are activated by clearly labelled buttons. The initial learning curve — typically one or two cook sessions — is limited to understanding when to use Sync versus Match. After that, operation is straightforward. The included cooking chart provides starting-point settings for common foods across all 12 presets, which removes the guesswork for new users.
Cleaning and Maintenance
Both cooking trays are removable and dishwasher safe. The non-stick surface releases food easily with a hot water rinse immediately after cooking. The dual-drawer format means two sets of trays to clean after each meal — a minor additional step versus single-basket fryers, but unavoidable with any dual-zone appliance regardless of brand. The exterior and display panel wipe clean with a damp cloth.
How Does the Salter EK4548 Compare?
Salter EK4548 vs Ninja Foodi MAX AF400UK
The Ninja AF400UK (9.5L, 2 × 4.75L, £149–£219) has larger individual drawers, the Ninja Smart Finish system and stronger brand recognition. The Salter EK4548 (8.2L, 2 × 4.1L, £69–£89) costs approximately half the price and offers more presets (12 vs 6). For households that want dual-zone cooking at a budget-friendly price, the EK4548 is a compelling alternative. For households who want maximum capacity per drawer and are prepared to pay the Ninja premium for build quality and brand confidence, the AF400UK is the stronger long-term investment.
Salter EK4548 vs Tower T17088
The Tower T17088 (9L Vortx dual basket, approximately £69–£99) is the EK4548’s most direct price-bracket competitor. The Tower wins on total capacity (9L vs 8.2L) and the Vortx technology heritage. The Salter wins on preset count (12 vs 6) and the 59% energy saving claim. Both use Sync-and-Match-style dual functions. The choice between them comes down to capacity preference versus preset breadth — both are strong at their price point.
Salter EK4548 vs Philips HD9270
The Philips HD9270 (6.2L single basket, £99–£129) is more expensive and has a single cooking zone with Rapid Air Technology. For single-dish cooking, the Philips’ 6.2L basket provides more total volume than either individual EK4548 drawer. For households who specifically need two-dish simultaneous cooking at different temperatures, the Salter’s dual-zone capability is the decisive advantage at a lower price.
Final Verdict: Should You Buy the Salter EK4548?
The Salter EK4548 is the best-value dual-zone salter air fryer in the UK market — and a genuinely compelling alternative to the Ninja AF400UK for households who want independent two-drawer cooking without the premium cost. The Sync and Match Cook functions work reliably in testing, the 12 presets including dehydrating cover more scenarios than most rivals at this price, and the 59% energy saving claim is the strongest dual-zone figure in this guide.
Its trade-offs are transparent: the individual drawers (4.1L each) are slightly smaller than the Ninja’s per-zone volume, the plastic build is less premium than higher-priced alternatives, and there is no app connectivity. For buyers who want dual-zone cooking from Britain’s oldest kitchen brand at a price that makes it genuinely accessible — the EK4548 is the one to buy.
