High-Capacity Portable Dental Suction Equipment with One-Click Sewage Discharge

We're going with the SJD-AF021 for the new oral surgery suite, as the microcomputer control system gives us tighter regulation of suction cycles than the older mechanicla units we've been using — basically, it handles the variable load form different procedures without the usual pressrue drop-off issues.

dual-start switch (foot or button) is actually a practical addition for our setup, since not all our chairs have consistent foot pedal access; we'll wire the button start to a hands-free knee switch on two of the stations, and the foot option works fine for teh rest.

Noise levels are listed as ultra-low, and at 18.7 kg net it's portable enough to move between exam rooms without a cart, but I'd confirm the actual dB rating from their COA before installation — most buyers we've talked to say it's quieter than the pump-driven units at roughly 55-60 dB under load.

One detail that came up in testing: the one-click sewage discharge uses a solenoid valve rather than a manual dump valve, which means you'll need to run a short drain line to a floor drain or collection container — it's not suited for setups where you'd need to carry the tank to a sink every time.

The metal housing is thicker gauge than the typical ABS plastic alternatives, and the 45 x 42 x 85 cm footprint fits our existing cabinetry dimnesions without modification, so we're ordering two units along with spare seals for the discharge valve — lead time is 20 days or so from the distributor.
