Air Cooler Water Tank Capacity: 6 L or 5.5 L? | Wanjiada

Why check air cooler water tank capacity before approving packaging?

Use the confirmed figure for the exact model, even when an older description gives a larger, rounder number. In our October 2026 catalog review, we confirmed the air cooler water tank capacity as 5.5 L, rather than retaining earlier 6 L wording, for three models: WJD980F-3L, WJD980F-3M and WJD880F-1M.

For an importer, distributor or private-label buyer, the question is not just which number belongs on a comparison sheet. It is which number to carry into the order specification, packaging artwork and your own product listing. Our correction offers a concrete example of why those documents should be checked together before approval.

What did we correct in these three model records?

We resolved the capacity discrepancy by confirming 5.5 L and bringing the affected descriptions, highlights and technical parameter information into agreement.

The correction recorded in October 2026 was:

Exact model	Earlier capacity wording superseded	Confirmed water tank capacity
WJD980F-3L	6 L	5.5 L
WJD980F-3M	6 L	5.5 L
WJD880F-1M	6 L	5.5 L

Our confirmation records establish the adopted value and the copy changes, but not the cause of the earlier discrepancy. This was a correction to product information, not a measured performance result.

Our WJD980F-3M model details show that confirmed capacity alongside the other model-specific parameters. Keep the complete model suffix in your records: a shared tank figure does not make different models interchangeable.

Can I round 5.5 L to 6 L in my product listing?

For these models, retain 5.5 L. Do not substitute the superseded 6 L wording simply because it looks neater on a carton or matches an older sales image.

If your purchasing brief requires a 6 L tank, ask about that requirement explicitly. A confirmed 5.5 L specification should not be described as meeting it without further clarification. The useful distinction is between the capacity you require and the capacity confirmed for the model—not between a convenient headline and a more precise table.

Our WJD880F-1M specification details use the same confirmed capacity. If you are considering another variant, check its own record rather than carrying a figure over from a similar-looking product.

How should I reconcile the documents before an order?

Resolve the conflicting field first, then check every document where that field will appear. We recommend this review sequence for your sourcing team:

1. Identify the exact model and configuration. Record the full model reference on the quotation, sample request and artwork brief. Do not shorten the reference to a shared family name when checking a disputed parameter.
2. Preserve both conflicting references. Keep the older image, sheet or email alongside the current specification. Ask which value supersedes the other rather than silently choosing the larger one.
3. Obtain written clarification. Ask the supplier to confirm the capacity for the model you intend to order. If the meaning or measurement basis is unclear, request that explanation as well.
4. Check the sample separately. Match its model reference to your agreed specification. Request a capacity-check record if your purchase depends on a measured result.
5. Align the buyer-controlled materials. Check packaging artwork, manuals, distributor sheets and online listings against the clarified value before approving them. Mark older versions as superseded so they are not reused later.

In our example, the website description, highlight and technical table were brought into agreement. Apply that same document check to your own order specification and private-label materials before approving artwork.

Does a confirmed tank figure also confirm runtime or cooling coverage?

No. The correction confirms the capacity field, not a refill interval, room-size rating or measured cooling result.

Our records for these three models do not supply water-consumption test results from which to verify operating duration. If duration matters to your brief, ask for a model-specific test record with its operating conditions and results. Keep that request separate from confirmation of the tank capacity.

The supply voltage and frequency also remain absent from these model records. Confirm them separately for the configuration you intend to order. One answered specification question should not be treated as proof of every other claim on an older advertisement.

What should I send when two capacity figures disagree?

Send the exact model reference, both conflicting documents and the capacity your purchasing brief requires. Include any packaging or listing artwork that already contains the disputed wording.

You can ask our team to clarify the model information before approving those materials. For the three models discussed here, use the confirmed 5.5 L figure—not the superseded 6 L wording—as the starting point for that discussion.
