The new Continuous-only Suction Regulators is a device with precise engineering instrumentation. It is lightweight and portable and comes in four vacuum ranges like 0-160, 0-200, 0-300, and 0-760 mmHg. To enhance its functionality, the device has three types of regulation which are manipulated according to its pressure relief - REG (regulated vacuum), OFF (with no vacuum), and FULL (full and unregulated vacuum). Since the gauges are dual scale, it offers more practicality and can be turned in the clock-wise manner. Of course, gauges that turn in counter-clockwise are also available. The face cover is made of ABS, which adds to its durability feature.
