I have at least 20 good used (tested) military surplus Rotron 'Propimax
2' fans. Dimensions are 3-1/4'' o.d.(round) x 1-1/4'' thick, 2-blade,
and run on 115 VAC 400 Hz. Usable in some older military radios or test
equipment. Original catalog price over $60 each, asking $4.00 each plus
shipping ( 12 oz. each ). These require a 0.15uF/400V cap for operation.
I can supply this cap (new) for an additional 50 c. Email for pictures
or call 334-347-5281 day/eve/wknd.
