Dynarex 33950 Oxygen Concentrator 5L Continuous Flow Machine

Dynarex 5L Oxygen Concentrator | Continuous Flow | 33950

The Dynarex 33950 is a medical-grade oxygen concentrator engineered to meet the 2026 standards of stationary respiratory therapy. Delivering a consistent, high-purity oxygen supply of up to 5 Liters Per Minute (LPM), this unit is designed for patients requiring supplemental oxygen for chronic conditions such as COPD, emphysema, or cardiovascular disease.

Unlike portable units that rely on pulse-dose delivery, the 33950 provides a continuous flow, making it compatible with CPAP/BiPAP machines and ensuring the patient receives a steady oxygen saturation levels throughout the day and during sleep.

Key Performance Features

• Continuous Flow Delivery: Adjustable from 0.5 to 5.0 LPM, providing the versatility to meet a wide range of prescription requirements.

• High Oxygen Purity: Utilizes advanced molecular sieve technology to extract nitrogen from ambient air, delivering an oxygen concentration typically between 90% and 96%.

• Intelligent Alarm Suite: Equipped with a comprehensive safety monitoring system to ensure patient peace of mind:

  • Low Flow-Rate Alarm: Alerts the caregiver if the output drops below prescribed levels.

  • Pressure Failure Alarm: Detects internal system obstructions or compressor irregularities.

  • Power Failure Alarm: Provides an immediate audible alert in the event of a disconnected power source or utility outage.

• Quiet-Drive Technology: Engineered for low-decibel operation, making it suitable for bedside use without disrupting the patient’s or caregiver's sleep.

• Integrated Humidification Port: Features a dedicated mounting area and connection for humidifier bottles, essential for preventing nasal dryness during long-term therapy.
