The SAR-830 series ventilators are our most popular small animal ventilators! Their legendary reliability rests on simple principles of operation and robust construction. Tidal volumes are generated by gating a known airflow into the lungs for a set inspiratory time. Only three controls — respiratory rate, inspiratory time, and flow rate are necessary to produce tidal volumes and respiratory rates over a wide range. Model SAR-830/AP (shown above) has the additional feature of pressure-cycling, where the lungs are always inflated to a set pressure on each inspiration. All models are available with Isoflurane or Halothane anesthesia.
