We run every GD-S350 through a 72-hour load test before shipping—motor cycling, water heating, suction pressure readings across 0.5-0.8MPa air range—and check the 24V water heater consistency at 0.2MPa feed pressrue, roughly 1% tolerance on the thermal trip.

The Taiwan motor holds up better than most budget options, and we've field-tested it on 50+ continuous cycles at 220V and 110V in our lab; the COA from our QC includes batch-level HPLC data on pure water system's heaters, not just a generic certifcate.


12-14 weeks for a full custom order with real leather or PU upgrades and a specific spittool color, but if you need a re-test of that 24V heater calibration before shipping, our company can do that for a small fee—we hold back one unit form each production batch for exactly this.

Those 9 programmable chair positions basically give you more flexibility for oral surgery suites, so clinic throughput goes up —the touch screen panel logs errors automatically, but real talk, we've seen zero heating failure in the first 200 units shipped to offices.

Our retest policy means you get a second COA when the chair arrives fresh from the transit wrap, and we guarantee ISO/CE certs match the batch number on your unit—it's pretty standdard, but some manufacturers skip teh final functional check for the rotatable spittool, we don't.
Our MOQ is 1 unit, so you can order exactly what you need for a single office or a trial run.
Lead time is usually 15-25 working days after order confirmation, depending on customization and current production volume.
Yes, we provide ISO and CE certificates with every unit, so you can verify compliance for your local regulations.
Absolutely, you can choose real leather or PU for the cushions when placing your order—just let us know your preference.
Store it in a dry, clean environment at room temperature, away from direct sunlight and moisture, to keep the electronics and upholstery in good condition.
