Precision Medical, PS3405, PS3400 Series Continuous & Intermittent 3 Mode Vacuum Regulator, Chemetron Quick Connect Source Connection, Tubing Nipple Patient ConnectionFeatures:Low vacuum ratesFactory preset timing cycles set at 16 seconds On, 8 seconds OffFully adjustable, 2-to-1 ratio timing cyclesModular components are attached to a cast metal back plate, simplifying serviceLarge, easy to grip knobsThe Three Mode Continuous & Intermittent model series provides reliable and accurate cycling of the regulator On and Off during the intermittent suctioning. The Three Mode Continuous & Intermittent series has a peak vacuum limit feature to prevent adjusting the vacuum too high. This series is ideal for sensitive applications where limiting Max vacuum is critically important. The intermittent timing cycle is factory set at 16 seconds on and 8 seconds off .Precision 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 unique modular design makes repair a breeze for any biomed or central supply department. The unit is made up of eight (8) 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 with its three (3) 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.
