Buying notes
Confirm these points before final quotation
The model works without a pump, while incoming water pressure still needs confirmation.
A3 should be presented as an under-sink RO product, not an outdoor or emergency filter.
Share water source, pressure expectation, and target market if you need model advice.
Distributor fit
When a non-electric RO model belongs in the catalog
A3-400 gives distributors an RO option for projects where buyers want to avoid a pump, power adapter, and plug-specific purchasing decisions.
The no-electricity positioning does not remove the need for a technical check. Incoming pressure and the intended installation environment should be reviewed before the model is quoted.
For a balanced catalog, compare A3 with higher-flow tankless A1 models and smart-faucet A2 models instead of presenting all RO systems as interchangeable.
