Basically we've been going back and forth with sourcing teams about chair reliability — VK-A8000 came up because of that it's one of teh few units where the motorized folding actually holds up under daily use, and the 9 memory positions aren't just a gimmick, they save real time between procedures.
Runs on 220V with a separate 24V motor circuit (so the chair movement doesn't interfere with the instrument controls), and you'll need water pressure between 0.2 and 0.4 Mpa plus air at 0.5 to 0.8 Mpa — pretty standerd clinic requrement anyway.

The ceramic spittoon rotates 90 degrees which is better than the fixed plastic ones for cleaning access, and the dual-volume saliva suction has a strong and weak setting that most buyers don't think about until they're dealing with different patient flows.

That 6-hole LED sensor light uses cold light so it won't heat up the work area, and the gradient adjustment is actually useful for crown preps where you need different intensity — just don't expect it to replace a surgical microscope for endo work.

It's ISO and CE certified, metal frame construction, and the gross weight is 220kg which means you'll want to confirm floor loading if you're on a second story — we usually have stock within 20 days or so, but confirm lead time because shippng on these can vary by port.
Also the package dimensions are 145x105x115cm, so make sure your receiving area can handle that before ordering, and the COA comes with each unit but you'll need to request the batch-specific one seprately.
Normally MOQ is 1 unit, so you can start with a single chair to test the market.
Lead time is around 15-20 working days after order confirmation, depending on stock.
Yes, the unit is ISO and CE certified, and we provide the certificates with the shipment.
The LED light is set at a standard medical color temperature, but we can adjust it upon request for bulk orders.
Store it in a dry, indoor space with temperatures between 5°C and 40°C, and avoid direct sunlight or moisture.
