Medical vacuum suction regulators come in continuous and intermittent models and are ideal for any critical care environment. They can also be used in all patient areas since they are considered combination units. The intermittent module provides a reliable and quiet means of cycling the suction levels on and off during intermittent mode. Adult models regulate to 300 mmHg, Pediatric models to 160 mmHg and Neonatal models to 100 mmHg. ON/OFF timing cycles operate independently and can be adjusted on the back plate of the unit without removing any casing. Pediatric and Neonatal models have positive pressure relief valves for safety. Units come in analog or with digital displays.
