This document concerns a device for airflow-assisted feeding of granular material in an agricultural implement, comprising an air inlet (1611, 1612), a material inlet (167), and an outlet (162) for material-laden airflow, a roof (163), the horizontal extension of which defines a material pickup zone (160), wherein the material inlet (167), air inlet (1611, 1612) and outlet (162) are connected to the material pickup zone (160), wherein the device furthermore comprises an air inlet valve (164) containing a valve seat (1641) and a valve body (1642). The valve body is rotatable about a geometric axis which is substantially perpendicular to a flow direction at the air inlet. The document also concerns a method for airflow-assisted feeding of material in an agricultural implement, a meter housing, and an agricultural implement comprising such a meter housing. It also concerns a frame for a material pickup module and a method for forming a meter housing.
