Product Description

OUCO Eco Hoppers are equipped with a simple but effective dust control system to minimize the escape of dust during the grab discharge cycle.

The hopper is divided into upper and lower section separated by a dust retention feature known as the Flex-Flap. The Flex-Flap comprises a series of pressed steel sections and vertical rubber flaps.

Flex-Flaps open to allow free flow of material into the hopper (green arrow in the diagram).

Flex-Flaps close to prevent the flow of air out of the hopper (red arrow in the diagram).

When material is released by the grab it falls through the Flex-Flap and accumulates in the inner hopper below. This will displace a volume of air which will attempt to escape the hopper into the atmosphere, taking with it an unacceptable amount of material dust.

The Flex-Flap has been designed to close due to the newly created pressure differential between the hopper and the atmosphere so forming a seal and effectively acting like a one-way valve such that the dust contaminated air is contained. Integral reverse jet filters are positioned around the hopper inlet to extract and clean the dust laden air. 

Collected dust is then recycled into the main stream of material. The Flex-Flap feature greatly reduces the volume of exhausted air necessary to control fugitive dust and hence facilitates the use of small compact filters instead of a large de-dusting system.
