16 -- MOTOR BLOWER ASSEMBLY POC Mr. William McCullough, 410-436-3705, Mr. John Scavnicky, 410-436-2555 E-MAIL: Click here to contact the technical point of contact, william.mccullough.2@sbccom.apgea.army.mil. The US Army Soldier and Biological Chemical Command (USASBCCOM) wishes to conduct a market survey for a commercial motor blower assembly which can adapt to the M45 Aircrew Protective Mask for Air Warrior applications. The performance requirements for the motor blower assembly are as follows: a) The motor blower assembly shall deliver 1.5 to 2.0 cubic feet per minute (CFM) of air against a head of 1.3 inches minimum of water when operated at a voltage between 0 and 28 volts direct current (VDC). b) The motor blower assembly may be powered by either battery or aircraft power. The 28 VDC aircraft power may be stepped down to match the power required by the manufacturer for the unit. The selected battery shall be capable of maintaining the airflow between 1.5 CFM and 2.0 CFM for a minimum period of 6 hours at a head of 1.3 inches minimum of water. Battery service/shelf life must either exceed 5 years or be rechargeable. The Department of Army Memorandum, 4 Jan 2000, Sub: Development, Acquisition, and Fielding of Weapon and Information Systems with Batteries, provides the list of approved batteries. c) The motor blower assembly shall contain a pusher-type of fan that will deliver positive pressure air to the air inlet of the C2 and C2A1 filter canisters for the mask. d) The motor blower assembly shall not impart Electromagnetic Interference (EI) that would interfere with aircraft operations. The motor blower assembly must comply with MIL-STD-461D and MIL-STD-462D e) The motor blower assembly shall be manufactured from materials that can withstand for a minimum period of 6 hours the corrosive effects of chemical/biological agents. f) The motor blower assembly shall be designed and manufactured from materials that can withstand the vibrations and shock encountered in helicopter operations. g) The motor blower assembly shall be designed and manufactured from materials such that it can be successfully operated between the environmental temperatures of -25F to 125F. h) The motor blower assembly shall remain serviceable when packaged and stored for ten years between the environmental temperatures of -60F to 160F. Manufacturers who express interest and have motor blower assemblies meeting the performance requirements shall provide to the government without cost the following: a) Any drawings, specifications, brochures, and photos, documenting the design of the system. b) The results of any tests documenting how the manufacturer's system or systems meet the performance requirements. c) The costs associated with the purchase of a single system and multiple systems. d) A sample prototype for a preliminary 30 day government evaluation. The Government will return the unit to the manufacturer after the 30 days. Posted 03/02/00 (W-SN430420). (0062)
