Portable Medical Suction Device 7A-23D1 - High Negative Pressure Low Flow Sputum Aspirator

Runs on 220V at 50Hz, pulls about 280VA max, and we’ve seen these units reliably hitting negative pressure above 0.09MPa — that’s 680mmHg for the sputum aspiration work it’s built for. The pumping speed is 35L/min at the air vent and 5L/min at the terminal, so it’s not for high-flow drainage but handles thick mucus just fine. Most buyers go with the 2500ml twin-container setup because you can swap one out without stopping a procedure.

Operating temp range is +5°C to +35°C, humidity at 80% or below, and it’s tested at atmospheric pressures from 86 to 106KPa — basically standard indoor conditions, not a field unit for extreme environments. Noise stays under 60dB, which is quieter than most aspirators we’ve stocked. What it’s not great for is continuous high-volume suction like gastric lavage; the flow rate tops out at terminal 5L/min for a reason.

We ship these with a COA from the factory, and HPLC data is availble on request for the internal tubing materials. pressure regulation system is mechanical, not electronic, so there’s less to fail — that’s a detail you wouldn’t get form a spec sheet. Usually stock about 50 units or so, but confirm lead time if you need more than 100.

OEM service is supported, white or custom colors, and the dimensoins are 350×190×285mm so it fits on a cart shelf. The HS code is 9018909911, which helps with customs clearance in most regions. We don’t include a carrying case by default, but it’s available as an add-on — ask about it if you’re moving it between rooms.
