Precision Medical, PM3116DHV, PM3100 Series Continuous 3 Mode Vacuum Regulator, Digital Mode, High Range Vacuum Gauge, Chemetron Quick Connect Source Connection, Diss Male Patient ConnectionFeatures:Color coded gaugesModular components are attached to a cast metal back plate, simplifying serviceDurable, break resistant caseLow to high vacuum ratesLarge, easy to grip knobPrecision Medical Continuous and Continuous & Intermittent Vacuum Regulators provide regulated, continuous and intermittent vacuum for tracheal and pharyngeal airway management, continuous negative pressure, chest drainage and surgical procedures.The Two Mode Continuous Vacuum Regulator model series regulate vacuum at low, medium and high levels up to maximum vacuum with gauge increments up to 300 mmHg. The Two Mode High Vacuum regulates vacuum at low, medium and high levels up to maximum vacuum with gauge increments up to 300 mmHg.The unique modular design makes repair a breeze for any biomed or central supply department. The unit is made up of six (6) easy-to-replace modular components.Unlike the normal plastic inlet and outlet connections on most units, the cast metal backplate connections are extremely durable, thereby saving unnecessary repair costs.As a result of its modular design, the unit is 25-50% smaller than other suction regulators making it the product of choice for crowded wall and rail areas.The case is made of strong plastic. It features a smooth surface with rounded corners making cleaning easy. The case also houses the gauge for extra protection.The large control knob and easy-to-read settings make vacuum adjustments simple, even in emergency situations.The Pediatric vacuum regulator is restricted to 170 mmHg (±10 mmHg) to prevent high vacuum situations and the gauge face is imprinted with the Precision Medical's 'Stork Symbol' to identify the unit for pediatric applications.
