# DFX-23A-II Electric Sputum Suction Machine — Ultra-Compact Portable Aspirator for Bedside and Home Use
Quick answer: The Keling DFX-23A-II is a portable electric sputum suction machine with ≥15 L/min free air flow, a negative pressure range of 0.013–0.07 MPa, a 1×1000 ml medical-grade plastic liquid vessel, ≤55 dB noise level and an exceptionally low 50 VA input power. It is manufactured by Keling Medical (Keling Medical) for hospitals, clinics and household first-aid use.
Quick Facts
- The Keling DFX-23A-II is a portable electric sputum suction machine in a compact, lightweight format for bedside and home use.
- Free air flow is ≥15 L/min with an adjustable negative pressure range of 0.013–0.07 MPa.
- Liquid vessel is 1×1000 ml medical-grade plastic, with a macromolecule suction bottle designed for easy disinfection and cleaning.
- Input power is only 50 VA — the lowest in the DFX-23A family — and noise level is ≤55 dB for quiet bedside operation.
- Power supply is 220 V ±10% 50 Hz ±2%; the maintenance-free oil-free piston pump requires no lubrication servicing.
- Built-in overflow protection prevents fluid from entering the pump assembly, and the one-piece ABS housing ensures a durable, compact build.
Overview
The DFX-23A-II portable electric sputum suction machine occupies the most compact and energy-efficient position in Keling Medical's DFX-23A series. With a 50 VA power draw — approximately one-third that of comparable models — and a lightweight one-piece ABS housing, it is particularly suited to prolonged bedside use, home nursing environments and settings where power consumption or weight are critical considerations.
Free air flow of ≥15 L/min and an adjustable negative pressure range of 0.013–0.07 MPa provide effective suctioning of sputum and other secretions for patients with moderate secretion volumes. The macromolecule (medical-grade polymer) 1×1000 ml suction bottle removes easily for disinfection and cleaning between uses, supporting infection control protocols in both clinical and home settings. An integrated overflow protection device keeps the maintenance-free oil-free piston pump safe from fluid contamination even if a caregiver fails to empty the bottle before it reaches capacity.
Operating at ≤55 dB, the DFX-23A-II generates minimal noise during suctioning — an important quality for patients undergoing extended treatments or those resting between sessions. The simple ON/OFF and vacuum adjustment controls on the front panel require no specialist training, making the unit accessible to home caregivers as well as nursing staff.
Key Features
- ≥15 L/min free air flow — sufficient suction rate for effective aspiration of sputum and moderate-viscosity secretions.
- 0.013–0.07 MPa negative pressure range — adjustable vacuum allows clinicians and caregivers to match suction strength to patient needs.
- 50 VA ultra-low power consumption — the most energy-efficient model in the DFX-23A range, suited to continuous home or ward use.
- One-piece molded ABS housing — compact and lightweight, designed for ease of carrying and repositioning between patients or rooms.
- Macromolecule suction bottle — 1×1000 ml medical-grade plastic vessel is simple to detach, disinfect and reattach for hygienic reuse.
- Maintenance-free oil-free piston pump — no lubrication required, keeping ongoing maintenance demands and costs minimal.
- Built-in overflow protection — safeguards the pump assembly from fluid ingress when the collection bottle approaches capacity.
