Tubular Drag Conveyor with Cage Dump Station
Keep material contained and the lab environment safe.
- Convey bedding in a completely sealed system. The sprocket drive slowly pulls a heavy-duty chain through a fully enclosed casing. As the chain moves material through the tube, there are no dusting or spillage issues.
- Cost-effective operation. The low-horsepower motor produces a slow, steady chain movement that offers reliable operation in an energy efficient way.
- Move challenging materials with little maintenance. Convey high-moisture, abrasive, easy-to-compact or smear materials without compromising operation.
- One conveyor does the work of several. Configure the tubular drag to convey material vertically, horizontally, at any angle and around corners. Multiple inlets and outlets allow for collective points throughout vivarium operations.
- Equipped for vivarium facilities. Multiple filters assure only clean air is returned into the room. Integral exhaust fan creates negative pressure inside hood to contain dust and odor.
