99 -- HUMAN RESPIRATOR SIMULATOR, DUAL PISTON SOL NO463A-98-Q-32802 DUE 040698 POC Mr. CHRIS DIEHL, CONTRACTING OFFICER, (850) 230-3100 The NAVY EXPERIMENTAL DIVING UNIT, Panama CIty, Fl., intents to procure the following via SIMPLIFIED ACQUISITION PROCEDURES: Dual piston human respiratory simulator. The simulator is to be operated in conjunction with a hyperbaric complex capable of all machine parts rated at a minimum 1500 psi working pressure. A variable tidal volume of 6.0 liters per stroke and a frequency of 40 breaths per minute at 330 psig is required. The ability to reproduce a true sinusoidal waveform shall 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 maximun 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, (850) 230-3100. Telephone request are unacceptable. Telfax request to: (850) 230-3147 (0077)
