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 percent smaller than other suction regulators making it the product of choice for crowded wall and rail areas. The case is made of strong ABS 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.
