Above Grade Receiving Hoppers

Airoflex Equipment’s above grade hoppers are designed to receive and reclaim large volumes of bulk materials such as wood chips, bark and other similar materials. Our design eliminates the need for a high maintenance pit and extensive civil work.

Airoflex’ bolted hopper design minimizes the need for field welding which results in lower installation costs. With safe operation and continued maintenance practices, our robust hoppers are engineered to have many years of trouble free operation and lower lifetime operational costs.

The standard Airoflex above grade hopper is designed to integrate with our extended arm truck or trailer dumper. To best suit our customer’s needs, Airoflex can configure a hopper using our modular accessories to suit any number of receiving applications.
