The LPU-40 flotation collar is a flotation device designed to support air crewmen stranded in water. The collar is attached to the air crewman’s flight vest. It provides a minimum of 65 pounds of flotation buoyancy and is designed to keep the user’s head above the water for an extended period. The LPU-40 is packed in a low-profile casing made of fire resistant ripstop material that meets Federal Aviation Regulations. The casing is designed to open when the dual-chambered bladder inflates.
A single pull beaded handle, when manually pulled, activates two 29-gram CO2 gas cartridges for inflation. Two oral inflation tubes allow the user to manually increase, decrease, or maintain the air pressure in the bladder chambers.
