A4 Pro Bladeless Tower Fan with Air Purifier
The A4 Pro is the flagship model in Keheal’s bladeless tower fan lineup, combining a bladeless fan and an air purifier in a single unit. The AEC six-stage purification system uses ACPure@ photocatalyst to break down formaldehyde (99.8% removal), TVOC 94%, bacteria 99.9%, and particles 95.1%, and is equipped with 260–280 nm UV sterilization and 28.93 million/cm³ negative ions.
On the airflow side it delivers 716 L/s, a 10 m throw, and 12 speed levels, with a noise level of 14.9 dB(A) at speed 1; rated at 220V~/50Hz with an ABS housing measuring 235×240×1120 mm.
A4 vs A4 Pro: What the Pro Upgrade Adds
Externally, present the difference only around ‘purification capability’ — never claim stronger airflow or lower noise. The standard A4 and A4 Pro share essentially the same fan, motor, housing, and controls, easing mixed container loading and shared materials; the Pro’s real upgrade is concentrated in the purification module.
| Dimension | A4 Standard | A4 Pro | Verdict |
|---|---|---|---|
| Purification stages | AEC five-stage | AEC six-stage (3mm fine grille / ACPure@ photocatalyst / HEPA / rear grille / UV lamp / tens of millions of negative ions) | Pro upgrade |
| Formaldehyde principle | Activated-carbon adsorption | Photocatalytic decomposition into CO₂ and water, claimed no secondary release | Pro upgrade |
| Quantified purification | No formaldehyde rate given | Formaldehyde 99.8% / TVOC 94% / Bacteria 99.9% / Particles 95.1% | Pro new |
| UV sterilization | None | 260–280 nm UV lamp | Pro new |
| Pollutants purified | 8 types | 12 types (adds formaldehyde / TVOC / bacteria / germs) | Pro upgrade |
| Negative ion concentration | 28.17 million/cm³ | 28.93 million/cm³ (negligible difference, not a standalone selling point) | Nearly equal |
Honest note on airflow and noise: Current data shows the A4 Pro at 716 L/s and 14.9 dB(A) on speed 1; the standard A4 at 733 L/s and 12.9 dB(A). The Pro’s higher wind resistance from added photocatalyst, HEPA, and UV modules is a normal physical effect — its upgrade is in purification, not airflow or quietness. The exact diff-parameter table for both versions is [to be confirmed with the factory].
Product Overview
Full product name ‘keheal · A4PRO Air-Purifying Bladeless Fan’, nameplate name ‘Bladeless Fan’, model A4-P (Fig.01, Fig.30). Dual positioning: ‘a bladeless fan and an air purifier’ (Fig.03).
Upright tower form, 235×240×1120 mm, ABS plastic, grey + white color (Fig.30). Coverage 35 m²; 30 air changes/hour in a 30 m² space (Keheal lab data, Fig.05, Fig.07, Fig.16). Business value (inferred): fans are a strongly seasonal category, and adding purification extends the sales cycle to year-round, lowering channel seasonal stock risk.
Key Features
AEC six-stage high-efficiency purification system (Air Efficient Clean); six-layer structure: 3mm fine grille → ACPure@ photocatalyst formaldehyde removal → HEPA filter (95.1% filtration) → rear grille → UV lamp (260–280 nm) → tens of millions of negative ions (28.93 million/cm³). Quantified purification: formaldehyde 99.8%, TVOC 94%, bacteria 99.9%, particles 95.1%, effectively filtering 12 pollutants.
On the airflow side: ACM dual-channel concentration & multiplication tech at 716 L/s, 550 mm elongated air duct, 10 m throw, 12 speed levels, 3D wide-angle oscillation 50°/80°/120°. Noise 14.9 dB(A) at speed 1, 42.5 dB(A) at speed 6; 360° sine-wave DC brushless motor + stabilizing bearing + MF-Vector algorithm + acoustic noise-reduction structure. Smart inverter constant temperature (drops one speed level per 1°C room-temperature drop); three wind modes (natural / inverter / sleep); 0–12 h timer; tip-over >45° power-off; child lock; display dimming; ‘Jade Disc’ round panel + IR remote; top hidden handle; fully bladeless and safe to touch; filter dust-cleaned every 2–3 months (not washable), consumables replaced every six months.
Technical Advantages
The formaldehyde path is catalytic decomposition: ACPure@ photocatalyst continuously breaks formaldehyde and TVOC into CO₂ and water, unlike adsorption schemes that re-release after saturation (Fig.09, Fig.10).
ACM (Air Centralization & Multiplication) dual-channel concentration & multiplication tech is patented, delivering 716 L/s airflow (Fig.15). The quiet chain has three stages: DC brushless motor reduces friction + innovative stabilizing bearing cuts vibration + acoustic noise-reduction structure blocks leakage + in-house MF-Vector algorithm ensures smooth running (Fig.20-21).
Power structure: just 3 W at speed 1, about 3 kWh for a summer (90 days × 10 h); about 20 kWh under smart inverter (Fig.22-23). Rated total power (with UV lamp and negative-ion generator at full load) is not listed in the spec table, [to be confirmed with the factory].
Specifications
Full parameters are in the spec table below (real values only). Rated power, standby power, net weight, carton count, outer-box dimensions, plug spec, 110V/60Hz version, HS code, and warranty period — all [to be confirmed with the factory] — are omitted and will come with the formal quotation.
Key items: 220V~/50Hz, 3 W at speed 1, 716 L/s, 10 m throw, 12 speeds, 550 mm duct, 14.9 dB(A) at speed 1 / 42.5 dB(A) at speed 6, 35 m², 99.8% formaldehyde, etc.
Quality & Compliance
Material-class tests (Fig.05, Fig.25, disclosed): ABS housing passes U.S. FDA food-grade testing, GB 4806.7-2016 food-grade, and EU POPs; SGS report conclusion ‘compliant’. These are material tests, not whole-unit electrical safety certifications; report numbers and the full institution name are [to be confirmed with the factory].
Electrical safety certifications: the detail page shows no CE / RoHS / FCC / ErP / UKCA / CCC marks or numbers, [to be confirmed with the factory]. Before launch, displaying unverified certification logos is prohibited, and material tests must not be presented as whole-unit certifications.
Safety design: fully bladeless and safe to touch, tip-over >45° auto power-off, child lock via long-press on the remote, display can be dimmed. Dual-function category compliance risk: when marketed as an ‘air purifier,’ some markets require CADR / coverage-area test basis, [to be confirmed with the factory].
Who Is This Product For?
Clear Customs First: Voltage, Plug & Certification Docs Ready in One Pack
Your real risk as an importer is not airflow, but whether the goods can be lawfully marketed once they reach port. The A4 Pro is currently registered as a 220V~ / 50 Hz domestic-spec model; the export voltage, plug, and certification plan will be provided together in our quotation.
Please tell us your destination country (EU / UK / US / MEA / SEA) when inquiring, and we will reply with the corresponding CE / RoHS / FCC / UKCA / ErP feasibility, certificate numbers and CoC, and the packing document list, so no re-testing is needed after arrival.
One special note: this unit is both a fan and an air purifier, so HS code classification (fan vs. air purifier) directly affects tariffs and the compliance path. We can coordinate with your broker to confirm this in advance.
Premium Line Positioning: Turn a Seasonal Fan into a Year-Round Business
The A4 Pro is Keheal's premium flagship in the bladeless tower fan lineup and forms a clear price ladder with the standard A4: the A4 targets entry-level volume, while the A4 Pro targets high margins. In channel negotiations you have two price points to work with rather than being locked to a single model.
More importantly, the sales cycle: a standard tower fan sells only in summer, but the A4 Pro's AEC six-stage purification (99.8% formaldehyde, 94% TVOC, 99.9% bacteria, 95.1% particles) lets it keep moving as an air purifier through autumn and winter, with far less inventory-turnover pressure than a pure fan category.
Filters and consumables (recommended replacement every six months) also bring ongoing after-sales repeat-purchase revenue. For wholesale tier pricing, regional partnership models, and marketing material support, please contact our sales team.
Easy to Sell at Shelf: A High-Ticket Item Explained in One Line — '99.8% Formaldehyde Removal'
The hardest part of in-store selling is a confusing pitch. The A4 Pro needs only two lines: 'It's a fan and a formaldehyde-removing purifier,' and 'just 14.9 dB at speed 1, lower than the 30 dB of a quiet bedroom' — both backed by authoritative test reports that customers grasp on the spot.
The safety points are just as clear: fully bladeless and safe to touch, ABS housing passes U.S. FDA food-grade testing, auto power-off when tipped over 45°, and child lock via long-press on the remote — leaving almost no objections from maternity or pet households.
The 1120 mm tower body commands presence on the shelf; open-stock gift boxes, multilingual manuals, and warranty policy can be customized to your channel needs. Request the packaging proposal.
Your Brand, Our Factory: A Flagship with a Ready Tech Story
The hardest part of building a private brand is 'what does the flagship say.' The A4 Pro comes with a complete tech narrative: AEC six-stage purification architecture, ACPure@ photocatalyst that decomposes formaldehyde rather than adsorbing it, 260–280 nm UV sterilization, 28.93 million/cm³ negative ions, ACM patented dual-channel concentration airflow, and 1+8 patents (invention patent ZL 2021 1 0124486.X).
Suggested brand strategy: use the standard A4 as the entry-volume model and the A4 Pro as the flagship that builds your brand's tech image; both share the same body size and accessory system, significantly lowering your packaging and material development cost.
Customizable directions include housing color (current standard grey + white), logo pad printing / laser engraving, exclusive model code, gift box and manual visuals, and branded filter consumable packaging. Please provide your brand book and target retail price, and we will respond on feasibility, tooling cost, and MOQ threshold.

MOQ, Lead Time, Tier Pricing & QC Process — Ask It All at Once
To improve inquiry efficiency, please state in your first email: target quantity, target market, packaging requirement (neutral / custom), and expected arrival time. We will reply in one go with MOQ, sample and mass-production lead time, tier pricing, payment terms, and port of shipment.
Product-side facts already confirmed for estimating freight and container load: housing 235 × 240 × 1120 mm, ABS material, standard package of main unit + power cord + IR remote + manual/warranty card + kraft paper box.
Note this is a seasonal + consumable category: fan peak season (Q1–Q2 stocking in the Northern Hemisphere) has tight capacity, so lock production early; also inquire about long-term filter consumable pricing and minimum reorder quantity. Carton count, outer-box dimensions, gross/net weight, and HS code will come with the formal quotation.
Start Small: Build Awareness with the Flagship, Then Scale
A new brand need not commit a full container upfront. The A4 Pro is a mature, in-production model with tooling and lines ready, so sampling lead time and first-order threshold are usually lower than a brand-new development project.
For a startup, its content value is high: '99.8% formaldehyde removal,' '14.9 dB,' and 'six-stage purification' are strong hooks ready for short videos and infographics, and spread more easily on social media than bare airflow numbers.
Suggested path: take 1–2 samples for content shooting and market testing → confirm color and packaging → launch a small first order → move to regular production after reorder. Confirm the low-MOQ threshold, sampling cost, and refundability with sales before writing them into the PI.
Full Containers & Mixed Loading: Balance Container Space with the Sales Season
The A4 Pro is a 1120 mm tower fan, a bulky category where carton count and outer-box size directly set per-unit freight, so confirm carton count and outer-box specs in the first inquiry, then back-calculate landed cost.
It can be mixed in a container with Keheal's small-volume items like hair dryers, curling irons, and handheld fans, filling the gaps between fan boxes to raise container utilization.
Volume strategy: the standard A4 covers the price band and the A4 Pro covers the margin band; both share the same body size for easy mixed loading. For full-container tier pricing, minimum mix ratio, and 20GP / 40HQ load counts, request the latest quotation from sales.
Container Planning & Mixed Loading Options
- Carton dimensions affect shipping calculation
- Container loading efficiency matters for landed cost
- Mixed SKU loading may improve container utilisation
- Spare filters can become repeat-order opportunities
