Functions & Features:

The HV-400B ventilator is gas driven by medical compressed oxygen and compressed air. In the inspiratory phase, two streams of compressed gas (compressed oxygen and compressed air) flow into a high performance air-oxygen mixer to form a mix of oxygen and air with a certain pressure.

The automatic conversion for standby power while AC power outage, keep working not less than 1 hour.

Air Compressor

  • Power: AC220V + 22 v, 50 Hz + 1 Hz and 300 va has a good reserve of single-phase ac power supply.
  • FUSE: Φ 5 x 20 / F8A
  • Output gas pressure: 0.3 ~ 0.4 MPa
  • Output gas minimum flow: ≥50L/Min
  • Output gas transient flow: ≥100L/Min
