The Direct Drive Aerator, MODEL DDA, features a deck-mounted gear reducer that ELIMINATES the need for a DRIVE-END BEARING.

The MODEL DDA can be equipped with either a Class II or III AGMA Gear Reducer.

These gear reducers have DOUBLE-SEAL protection on the input shaft and output hub.

The DDA model aerator is available with a slow or fast turning gear reducer (70 or 80 RPM rotor speed).

Our Direct Drive Aerator eliminates belts, side loads on the input shaft and a low speed coupler.

Stainless steel drive and tail shafts are computer machined in our plant
 for maximum quality control

Rotors are precision and balanced for smooth operation

Welded, pressure-checked floats are .090 thick 5052 marine grade 
aluminum. Saltwater aerators have 16 gauge, 304L stainless steel
floats

Field-researched spiral placement of blades are welded onto the rotor
tube

Quality components and design contribute to very low maintenance

Oven-fused TGIC high quality powder coating is the standard finish.
Galvanized and stainless steel units are available for saltwater.

The tail bearing is a water lubricated Ultra High Molecular Weight 
(UHMW) polymer bearing

Paddles are spiral mounted for smooth performance and robotically
welded on both sides for strength and corrosion resistance

Pivoting mooring arm system allows the aerator to automatically adjust
to different water levels
