Description: If you own a 12” Dam Toys Gemini Astronaut or GI Joe Mercury Astronaut figure, this Portable Oxygen Ventilator is for you! This 1/6 scale POV is part of the Full Earth Workshop Collection of Historical Astronaut Figures and Space Artifacts. It has been modeled from actual artifacts in the Smithsonian archives. This POV was used late in Project Mercury and through the entire Gemini program. This POV was modified for Apollo and Skylab. See the images of Gordon Cooper (Mercury) and Frank Borman (Gemini) on the way to launches with this POV. I have been able to lower the price to less than our Shapeways sintered product with new very nice FDM print technology. It is shipped in white- it can be displayed as-is or painted details can be added as shown in the images. This auction includes just the 1/6 scale Portable Oxygen Ventilator, not the astronaut figures shown. Oxygen hoses can be found online from GI Joe, Dragon, Dam Toys! And DiD Astronaut figures. Hoses can be easily created by covering nylon tubing (from eBay or a hobby shop) with adhesive athletic tape! You can find 1/6 scale astronaut / pressure suit hardware from the 1930’s to Mercury, Gemini, Apollo, and SpaceX available on our Shapeways shop. Just look for the Full Earth Workshop! Here is more information on the POV from NASA documents: Ventilators Ventilators are portable sources of cryogenic air or oxygen used with suited crewmen. They were used on Project Mercury and the Gemini Program to a lesser degree. The ventilators used in the Apollo Program were used for three distinct purposes. The Apollo portable oxygen ventilator (POV) (fig. 50) is designed primarily to maintain a crewman or a test subject in a preoxygenated state before launch or altitude testing. Because of the decompression involved, nitrogen must be purged from the subject to avoid the bends, and it is imperative that the subject be maintained in a 100-percent-oxygen environment for several hours before decompression. The POV is a hand-carried, self-contained, life-support unit capable of performing this function while providing some degree of cooling. The operation of the unit is relatively simple. The LOX or the liquid air is stored in a Dewar flask. A buildup valve allows some liquid to boil, maintaining the pressure at 1034 to 1103 kN/m2 (150 to 160 psig). Opening the supply valve allows this pressure to force liquid out the bottom of the Dewar flask into a heat exchanger. The liquid boils and absorbs heat in a series of heat exchangers. A diverter valve alters flow through a heat exchanger to regulate the gas temperature. The gas then is routed to the diffusion pump and exhausted through an ejector into the suit loop. The gas, having achieved a high velocity at the ejector, impinges on the gas in the suit loop, providing the force for a ventilation flow of at least 0.28 m3/min (10.0 scfm).
