99 -- HUMAN RESPIRATOR SIMULATOR, SINGLE AND/OR DUAL PISTON SOL N0463A-97-Q-36015 DUE 022497 POC Mr. CHRIS DIEHL, CONTRACTING OFFICER, (904) 230-3100 The Navy Experimental Diving Unit, Panama City, Fl. intends to procure the following via SIMPLIFIED ACQUISITION PROCEDURES: Single and/or dual piston human respiratory simulator. The simulator is to be operated in conjunction with a hyperbaric complex capable of being pressurized to 330 psig. A variable tidal volume of 6.0 liters per stroke and a frequency of 40 breaths per minute is required. The ability to reproduce a true sinusoidal waveform will be part of the criteria, as well as acceptance of an outside source waveform in order to more closely simulate human respiration. Piston seal design must retain all process gas at maximum pressure differential in order to facilitate closed circuit breathing apparatus evaluations. Proper compatibility of all wetted surfaces with 100% oxygen and high salt environment is essential. Analog output of piston position is required in the range of 0-5 volts DC with minimal distortion and maximal resolution. Technical point of contact: Mr. David Cowgill. (904) 230-3100 Telephone request are unacceptable. Telfax request to (904) 230-3147. (0043)
