Ampair's 100 watt UW100 water generator (formerly the Aquair UW) is a very durable, versatile solution for home or marine hydroelectric power for 12V, 24V and 48V DC power systems. The forward facing shrouded 3 bladed propeller drives a permanent magnet alternator producing up to 8 Amps output current for a 12 volt system.

The propeller, cable exit and rear of the casing are all double sealed. The alternator body is filled with hydraulic fluid, with a reservoir in the rear end casing, to prevent corrosion and equalize pressure changes caused by depth and ambient temperature.

Effective January 2008 comes standard with the Shrouded Propeller, to prevent seal damage from fishing line or debris. A low rpm propeller is also available for high water speed locations (flow of 8 knots - 4 meters per second - or greater), and an anti-clockwise propeller (the low-RPM and anti-clockwise options are typically special order only). Also available: a stainless steel propeller guard cage and mounting hardware.

All voltages typically in stock with standard shrouded props and ship from the Renton, WA location. Call if need quantity availability.
