Acquired this SAS subdriver and fittings kit for the Moebius Seaview from Paul Crozier down in Houston. 
For the newbies, this unit is equipped with a low pressure blower which initially scavanges air inside the cylinder to blow the ballast tank. Once the snorkel mast breaks the water surface the partial vaccum inside the cylinder is relieved and air from the surface is used to completely blow the tanks dry.
The pump has a control board soldered to it. The board comes with a servo lead and what I assume are power leads.
Is the power lead connected directly to the battery (7.4v) or does it need to be a lower voltage? IIRC these small pumps are rated to about 5v only.
Also, can one hook up the LPB controller and vent valve servo off of a single channel?
BTW, is it alright to store a subdriver with the endcaps on for extended periods? Do the o-rings deform over time?
