A Prout Escale 39 owner's well illustrated account of how he increased the air supply to his engine.
Two types of sheet, one for higher frequencies, usually generated by gasoline engines and electric motors, and a second for the low to mid frequency ranges usually associated with diesel engines.
Blowers, ventilators, air hose (3" or 4"), and collector boxes for engine compartments, galleys, bilges, and heads.
140 cu. Ft. per minute and larger extractor fans remove air quickly from galley, head, or engine room. May be mounted remotely via hose. "Ignition protected, virtually silent."
Two sizes of 120-volt forced-air heaters to keep your engine from freezing and help it start easily in cold weather.
