4、AC shall be configured in a tubular metal frame. The frame shall be configured to protect the BAC components from rough handling of the unit as well as provide for convenient lifting points when transporting the BAC. The frame shall be composed of a metal that provides resistance to corrosion in a s
5、ea/salt environment. 2.1.4 Carrying handles. The BAC frame shall be provided with four conveniently located carrying handles (each at diametrically opposed corners of the unit) to facilitate transporting the BAC aboard ship. The carrying handles may be retractable in order to maintain the specified
6、size requirements for stowage of the BAC. With the handles extended, the overall size of the BAC shall not exceed 60 inches long by 20 inches wide by 30 inches high. 2.1.5 Casters. The BAC frame shall be mounted on four heavy-duty casters to facilitate transporting the unit on flat surfaces. Each ca
7、ster shall have a nominal rated capacity of at least 250 lbs. The bracket and bearings must resist corrosion in a sea/salt spray environment. 2.1.6 Engine. An air-cooled diesel engine shall drive the BAC. The engine may be modified to provide some level of corrosion resistance when exposed to a corr
8、osive environment. 2.1.7 Purification system. The BAC shall have a purification system that includes an oil-water separator, a condensate drain valve, and a breathing air purifier. A backpressure regulating valve and check valves shall be provided, as required, to ensure proper operation of the puri
9、fication system. The breathing air purifier shall employ a single, user-replaceable air purifier cartridge with a processing capability of at least 15,000 standard ft3of air based on an inlet air temperature of 70 F.

12、ded with two fill hoses (charging whips), which permit filling of either a single SCBA cylinder or two SCBA cylinders simultaneously. The end of each fill hose shall be provided with an air shut-off valve, a pressure gauge, an air bleed valve, a relief valve and a CGA-347 fill hose adapter to facili
13、tate filling 4500 psig SCBA cylinders. Each fill hose shall be six feet in length (+/- six inches). The BAC shall also be equipped with corrosion resistant stowage brackets for the charging hoses. 2.1.9 Corrosion resistant high pressure fittings. The BAC shall be provided with corrosion resistant au
14、stenitic stainless steel tubing, tube fittings, high pressure instrument piping, and fill hose fittings. The CGA-347 fill hose adaptor fittings shall be either stainless steel or anodized aluminum. 2.1.10 Breathing inlet air filter and hose. A detachable breathing air inlet filter and inlet air hose
15、 shall be provided with the BAC. The nominal length of the inlet air hose shall be 10 feet (+/- one foot). The hose shall have some type of reinforcement incorporated into its design to prevent excess bending or kinking of the hose during stowage. 2.1.11 Hour meter. The BAC shall have an elapsed run
16、 time meter, incremented in hours. The meter shall operate when the diesel engine is running. The meter shall be able to operate properly when exposed to interference from the conditions that exist within a shipboard environment such as vibration from ship movements. 2.1.12 Moisture/CO level indicat
17、or. The BAC shall be equipped with a means of monitoring the moisture and CO levels. 2.1.13 Relief/safety valves. The BAC relief valves shall be tagged with the following information: a. Pressure setting b. Set date 2.1.14 Pressure gauges. The pressure gauges should be labeled with the calibration d
18、ate. 2.2 Performance characteristics. 2.2.1 Air pressure. The BAC shall deliver air for charging breathing air cylinders to a nominal pressure of 4500 psig. The outlet air pressure setting shall be user-adjustable via a relief valve or similar device. The BAC shall be capable of delivering breathing
19、 air at a maximum pressure of 4950 psig. 2.2.2 Free air delivery. The BAC shall have a free air delivery of at least 5.0 standard cubic feet per minute (SCFM) at an outlet air pressure of 3000 psig. 2.2.3 Air quality.
