Commercially Available Performance Inc. Regulators
Abstract
Evaluations were conducted on Performance Inc, Chapel Hill, NC, PDXL 700 and PDXL 1000 regulators, to determine which commercially available open- circuit SCUBA regulators were capable of meeting performance goal standards for Navy use. Bench testing of all candidate regulators was conducted to establish flow patterns and air delivery capacity. Unmanned testing using a breathing simulator at ventilation rates of 22.5, 40, 62.5, and 90 L/min at test depths of 0 to 60 msw (0 to 198 fsw), in 10 msw (33 fsw) increments was conducted to determine work of breathing (WOB) values. Each candidate regulator model was subjected to five runs each and a mean of the WOB was established. This mean WOB value was then compared to the Performance Goal Standard of 1.37 Joules per liter (J/L) at 60 msw (198 fsw). Testing was conducted in ambient temperature water, approximately 21 dec C (70 deg F), with a supply pressure of 10.34 MPa (1500 psi). All testing conducted determined that none of the candidate test regulators were capable of meeting the requirements for acceptance by the US navy.
