Overview

The DFX-23B-II portable electric suction machine addresses the suction needs of mobile clinical environments — ambulances, field emergency units, home visits and surgical procedures where mains power may be unavailable or interrupted. Its AC/DC automatic switching capability means the unit transitions seamlessly between mains and vehicle power without operator intervention, and the built-in battery extends operational independence for up to 2 hours when no external power source is accessible.

With ≥28 L/min free air flow and a vacuum range of 0.013–0.085 MPa, the DFX-23B-II delivers strong, adjustable suction for aspirating blood, sputum and other viscous secretions encountered in surgical and emergency scenarios. The maintenance-free oil-free piston pump requires no lubrication or oil changes, reducing maintenance burden in settings where servicing infrastructure may not be readily available. Built-in overflow protection prevents secretion fluid from reaching the pump if the 1000 ml collection bottle fills during an extended procedure.

The high-quality cold-rolled steel housing with electrostatic spray finish gives the DFX-23B-II the structural durability expected in ambulance and field kit, while keeping the unit compact and portable for rapid deployment. Automatic overcharge protection ensures the battery is maintained safely during periods of mains charging without operator monitoring.

Quick facts

The Keling DFX-23B-II is a portable electric suction machine specifically designed for surgical procedures, ambulance use and field emergency applications.
Free air flow is ≥28 L/min — the highest in the DFX-23A/B portable series — with a negative pressure range of 0.013–0.085 MPa.
The DFX-23B-II supports both AC mains (220 V ±10% 50 Hz ±2%) and DC vehicle power supply, with automatic AC/DC switching that does not interrupt operation.
Integrated self-storage battery provides up to 2 hours of continuous operation without external power, and built-in overcharge protection stops charging automatically when the battery is full.
Liquid vessel is 1×1000 ml medical-grade plastic; noise level is ≤55 dB and input power is 150 VA.
The cold-rolled steel housing with electrostatic surface spray provides a durable, professional-grade casing suited to the rigors of ambulance and field environments.

Questions buyers ask

What is the Keling DFX-23B-II portable suction machine used for?

The DFX-23B-II is a dual-power portable aspirator for aspirating blood, sputum and viscous secretions during surgical procedures, ambulance transport and field emergencies. Its AC/DC switching and up to 2 hours of battery supply make it suitable for pre-hospital emergency care and mobile clinical environments.

How does the AC/DC power switching work on the DFX-23B-II?

The DFX-23B-II automatically detects and switches between AC mains power (220 V) and DC vehicle power supply without operator intervention, ensuring continuous operation during transitions — such as moving a patient from an ambulance bay to a hospital ward.

What is the battery life and charging safety of the DFX-23B-II?

The integrated battery provides up to 2 hours of autonomous operation. A built-in overcharge protection circuit automatically stops charging when the battery reaches full capacity, preventing overcharging and maintaining long-term battery health without manual monitoring.

Can the DFX-23B-II be supplied for ambulance fleets or in bulk?

Yes. Keling Medical supplies ambulance fleet operators, hospitals and equipment distributors worldwide through its Shanghai export center. Contact Keling Medical at https://www.kelingmed.com for fleet pricing, customization options and export terms.
