How it works

The Raceway Cleaner is propelled by the water flowing through the waterway, thus requiring no other source of power to perform its cleaning job. The speed depends on the volume of water flowing through the raceway or trough. When placed at the top of the raceway, water starts building up above the device, pushing it down the raceway. A specific amount of water is allowed to escape under the unit.

Attached to a main frame of the unit is a scrubber (on concrete raceways, steel-bladed brooms are used, while a rubber squeegee is used for plastic hatchery troughs). The scrubber will loosen most solids adhering to the bottom of the waterway, allowing them to be flushed ahead of the device.

In raceways having heavy concentrations of fish, it will become necessary periodically to raise the cleaner, permitting fish to exit upstream into the clean portion of the waterway; the unit may then be lowered back into position for cleaning to continue.

The construction of the Raceway Cleaner makes it both durable and lightweight. The frame is constructed of aluminum. The side and bottom flaps are made of heavy rubber. The heavy rubber on the sides allows the unit to compensate for several inches of variation in width of raceway and trough walls. The bottom flap attached to the water restrictor will compensate for uneven raceway and trough bottoms. These cleaners can be built for any size trough or raceway.
