The unique design of the 300mmHg Continuous Vacuum Regulator has 6 modular components, which allows for easy repair by central supply or biomed departments. Unlike many units that have plastic inlet/outlet connections this unit is made to last. It is made from tough ABS plastic and a cast metal backplate, making it very durable and reducing repair costs. Rounded corners make it easy to clean. This module is 25% to 50% smaller than other suction regulators on the market, making it convenient for crowded spaces. Large knobs and gauges make it easy to set and read even in an emergency.
