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.

Custom colors are available. Please call customer service at 1-800-272-7285 for details.

   Caution! U.S. Federal law restricts this device to sale by or on the order of a physician.
