7L Air Fryer at 214 W per Litre: The Wholesale Trade-off
A 7L air fryer that loads 1,646 units into a 40HQ container beats our 5.5L model by 28 units — the freight arithmetic rarely runs the way buyers assume. A 7L air fryer is a countertop convection cooker sized for family batches, and the UAHAF29 pairs 7 litres with 1500W, two mechanical knobs and a viewing window at $19.09 per unit.

// 02 — Definition
What is a 7L air fryer, and who is it for?
A 7L air fryer is a countertop convection cooker with a 7-litre basket, a heating element above the food and a fan that drives hot air around it. At 7 litres it takes a whole chicken or roughly 600 g of frozen fries in one load.
How many portions does 7 litres actually hold?
Seven litres takes a 1.5–2 kg chicken, a 9-inch pizza base, or about 600 g of frozen fries in a single load. Loose food needs headroom for airflow, so usable volume always sits below nominal volume on a basket fryer.
For a retail buyer that puts the model in the family tier of a range — above the 3.2L and 4L single-household units, below the 10L oven-style machines.
Which retail buyer does a 7-litre basket suit?
Supermarket chains and appliance distributors selling into households of four or more. The UAHAF29 pairs that capacity with mechanical knobs rather than a touch panel, which holds the bill of materials — and the shelf price — below digital models in the same litre class.
It also suits promotional programmes. Mechanical controls carry fewer failure modes than a capacitive panel, and the indicator light gives a demo unit something to show on a shop floor.
What does the viewing window change?
The window and its indicator light let the operator watch browning without pulling the basket. On a mechanical unit that matters more than on a digital one: there is no cooking programme to lean on, so looking replaces a preset.
It is also what separates this SKU on a shelf from knob-only competitors at the same price point.
// 03 — Specifications
UAHAF29 specifications, line by line
The UAHAF29 runs 1500W at 110-127V or 220-240V, 50/60Hz, over a 7-litre removable PTFE pot. The housing is ABS over cold-rolled steel. Two knobs set the 80-200°C range and a 30-minute mechanical timer, with an overheat cut-out behind both.

| Product size | 340x280x325 mm | Fits a standard 350 mm counter depth |
| Net weight | 3.9 kg | One-person shelf stocking, at 4.7 kg gross |
These are catalogue figures taken from our production record. The signed golden sample governs the contract, and that caveat applies to every number on this page.
Why the 1500W rating matters at 7 litres
1500W is the same element rating we fit to the 5.5L UAHAF11. Spread across 7 litres it yields 214 W per litre instead of 273. The basket still reaches 200°C. It simply takes longer to climb back there after the drawer is opened.
In practice that shows up as a preheat instruction on the packaging insert, not as a cooking failure. Programmes that drop the preheat line collect the complaints.
What the 80-200°C range covers
The low end suits dehydrating and reheating. 160-180°C is the working band for fries and wings. 200°C handles browning and finishing. The knob is analogue, so marked positions are nominal rather than a calibrated setpoint.
// 04 — Heat density
Watts per litre: the 7L air fryer trade-off
Heat density — watts divided by litres — predicts recovery time better than raw wattage does. The UAHAF29 sits at 214 W per litre, the lowest figure in our basket range. That is a design choice: a bigger basket on the same element trades speed for batch size.
How does the 7-litre model compare on heat density?
Across four models built on the same platform, heat density falls as capacity rises: 375 W/L on the 3.2L UAHAF23, 300 W/L on the 4L UAHAF35, 273 W/L on the 5.5L UAHAF11, and 214 W/L here.
None of those numbers is a defect. They set expectations. The 3.2L reaches temperature fastest, while the 7-litre unit feeds the most people per cycle.
Does lower heat density mean worse results?
No — it means longer cycles at full load. Half-loaded, the 7-litre basket behaves like a smaller unit. Packed with frozen product straight from a freezer, it needs more time than the 4L, and the manual should say so plainly.
Buyers compare litres and watts separately. The number that predicts a return rate is the ratio between them — at 214 W per litre a large basket needs a longer preheat, not a bigger fan.

// 05 — Range comparison
How does the 7L air fryer compare with our 3.2L, 4L and 5.5L models?
Against our own 3.2L, 4L and 5.5L units, the UAHAF29 is the cheapest per litre at $2.73 and the slowest to recover heat. The 5.5L UAHAF11 is the only sibling that opens at a 10-unit tier, which makes it the natural sampling model.
| Model | Capacity | Rated power | Heat density | Entry tier | From $/unit |
|---|---|---|---|---|---|
| UAHAF29 This model | 7 L | 1500W | 214 W/L | 500 units | $19.09 |
| UAHAF11 | 5.5 L | 1500W | 273 W/L | 10 units | $17.70 |
| UAHAF35 | 4 L | 1200W | 300 W/L | 500 units | $11.92 |
| UAHAF23 | 3.2 L | 1200W | 375 W/L | 500 units | $11.93 |
Cost per litre across the range
Divide entry price by capacity: $2.73 per litre on the 7-litre model, $2.98 on the 4L, $3.22 on the 5.5L and $3.73 on the 3.2L. Capacity is the cheapest thing to buy on this platform. The control system is what costs money.
Where each model wins on a shelf
The 3.2L is a price-point entry unit. The 4L is the volume seller for small households. The 5.5L samples cheaply at ten units. The 7-litre UAHAF29 is the family flagship of the mechanical range, and the only one of the four with a window.
// 06 — Freight
Freight math: 1,646 units in a 40HQ
The UAHAF29 packs four units to a carton at 0.165165 CBM, which gives 629 units in a 20ft, 1,307 in a 40ft and 1,646 in a 40HQ. Carton gross weight is 19.8 kg, so a full container sits well inside any weight limit.
Cartons, CBM and container fill
Each carton measures 650x330x770 mm and holds four units. Net weight per unit is 3.9 kg against 4.7 kg gross, so packaging adds roughly 1.05 kg to every shipped unit once the master carton is counted in.
At the 1,000-unit tier price of $18.90, a full 40HQ of 1,646 units comes to $31,109.40 FOB before freight and duty.
Why the 7-litre ships denser than the 5.5L
Counter-intuitively, the larger model loads more units. The UAHAF29 carton is 0.165165 CBM for four pieces. The 5.5L UAHAF11 carton is 0.168036 CBM for the same four. That is 1,646 units per 40HQ against 1,618, or 28 units more from the bigger basket.
The reason sits in the product dimensions: 340x280x325 mm for the 7-litre unit against 350x300x340 mm for the 5.5L. It is smaller in every dimension and still holds 1.5 litres more.
// 07 — Manufacturing
How we manufacture this model
Production runs in our own Guilin plant rather than through a subcontractor. Housing parts are moulded in-house, the heating assembly is powered up before the housing closes, and every unit passes a function test before it is packed for export.
In-house tooling and moulding
The ABS housing, knob set and window frame run on our own moulds across seven assembly lines in a 15,000 m² facility staffed by 205 workers. Private-mould variants are possible where programme volume supports the tooling cost.
Element, fan and wiring burn-in
Each 1500W heating assembly and its fan motor are powered up on the line before the housing is closed. Dual-voltage wiring is set for the destination market at this stage, together with the rating label.
Quality control and function test
Knob travel, timer bell, thermostat response and the overheat cut-out are exercised on every unit. PTFE pots are inspected for coating defects and the window seal is tested before the carton is sealed.
Certification and warranty
Export units are built to CE and RoHS requirements, with LFGB and REACH documentation issued per order. Every order carries a 12-month warranty against manufacturing defects. Certification names and scope are listed in our Trust Center.
// 08 — Commercial terms
Wholesale terms: MOQ, tiers, lead time and Incoterms
The UAHAF29 price ladder opens at 500 units and $19.09, falls to $18.90 at 1,000 and $18.71 at 2,000. Lead time is 15 to 30 days after the sample is signed off. We quote FOB China, with EXW and CIF available, on 30/70 T/T terms.
Tier pricing on the UAHAF29
Three volume tiers set the working ladder.
| Order quantity | Price per unit | Saving vs entry tier |
| 500 units | $19.09 | — |
| 1,000 units | $18.90 | $0.19 |
| 2,000 units | $18.71 | $0.38 |
The step from 500 to 2,000 units is $0.38 per unit, or $760 across a 2,000-piece order. That is real money on a thin-margin appliance, but it is not the main lever. Freight per unit moves more than price per unit does.
Lead time and payment
Production runs 15 to 30 days after the deposit lands and the sample is signed, depending on order size and customisation. Terms are 30/70 T/T: 30% deposit, 70% against the bill of lading. FOB China is our default Incoterm.
Voltage and plug by market
The UAHAF29 is built dual-voltage at 110-127V and 220-240V, 50/60Hz, so a single SKU serves North America, Europe, the UK and Australia. Plug type, cord length and the rating label are set per destination during the OEM run.
OEM, ODM and private-label work covers branding, knob and panel finishing, colour, packaging and manual artwork. Send the artwork with the target voltage and we will price tooling and sampling against it.
// 09 — Compliance
PTFE, overheat protection and the standards buyers ask about
Two questions arrive on nearly every air fryer enquiry: whether the non-stick coating is food-safe, and which safety standard the appliance is built against. Both have documented answers. The coating falls under FDA food-contact rules, the appliance under IEC 60335-2-9.
Is the PTFE pot food-safe?
PTFE used as a food-contact surface is covered in the United States by the FDA under 21 CFR 175.300 for resinous and polymeric coatings. PTFE stays stable far above the 200°C ceiling of this appliance.
For EU-bound orders, LFGB and REACH documentation is issued against the specific order rather than held as a blanket certificate, because the applicable scope changes with the coating supplier.
Which safety standard applies to an air fryer?
Portable cooking appliances sit under IEC 60335-2-9, the particular requirements for grills, toasters and similar portable cooking appliances, alongside the general IEC 60335-1. CE marking for the EU rests on the LVD and EMC directives.
The overheat cut-out is the component that abnormal-operation testing works hardest, which is why it is exercised on every unit rather than sampled per batch.

// 11 — Verdict
When the 7-litre unit is the right line item
Take this model when the shelf needs a family-capacity mechanical fryer at the lowest cost per litre in the range. Skip it when the programme is built around fast single portions, because the 4L UAHAF35 recovers heat faster and lands $7.17 cheaper per unit.
The trade-off is explicit. 214 W per litre buys 7 litres of basket, a viewing window and 1,646 units per 40HQ, at $2.73 per litre. Price it against the 5.5L UAHAF11 before you commit the shelf, because the two sit closer on freight than on capacity.
