I purchased some surplus ventilation units for my enclosed flightdeck (this isn't a problem in my open cockpit :) ), that have an integrated blower motor and cool brushed aluminum "eye" that allows you to direct the flow as well as shut it off.These are the kind you're used to seeing over airliner seats in the passenger section.I'd like to use the integrated motor rather than replace it or use a large master blower for all four vents, but I don't know the voltage requirements. I seem to recall that airliners use weird AC voltages on board, and before I start "smoke-testing" the motors I thought I'd throw the question out here.Any clue what voltage is common in the overhead lights/vents of airliners? The unit is made by Torin and has a 3 pin Molex connector. One wire goes to ground, one to the switch integrated into the "eye", and the third to the motor. In between there appear to be a couple resistors or such.Thanks for your help. If it will help, I could get photos in a day or two.Just a shot in the dark... any suggestions out there?Chris

Chris,Another shot in the dark! ;-)Seems a common voltage/frequency for airliners are 115V at 400 HzDoesn't the motor have some kind of data tag? Should be printed there.Regards,

Mats,Thanks for the info! That sounds familiar... but I don't think I'm going to build some kind of 400hz converter. I think I'd be better off finding a dc motor that will fit the mounts.Oh, and believe it or not there were no markings on the motor indicating its specs... that would've been too easy, huh ;).Chris
