The company says its improved Periflow diffuser system is specifically designed to meet the demanding airflow requirements of hospital operating rooms. The company says Periflow effectively isolates the patient from airborne contaminants, while controlling both the velocity and dispersal pattern of the air. The two-component system consists of perimeter slot diffusers, to enclose the operating area in a linear air curtain, and center laminar flow diffusers, to ventilate the area within the air curtain. According to the manufacturer, "this air curtain essentially creates a room within a room."
