GNA/GVA series
Straight overloading augers with rear discharge - GNA/GVA series
The GNA/GVA series overloading augers are the classic among overloading augers.
They are primarily used for filling seed drills and fertilizer spreaders with low loading heights and are manufactured by us in galvanized steel (GNA) or stainless steel (GVA) versions.
With a conveying capacity of 25 to 70 tons per hour and diameters of 150 to 225 mm, these robust screw conveyors can easily handle even intensive continuous applications. Available in corrosion-resistant stainless steel for demanding environments or in proven steel finishes for standard applications, they offer the optimal solution for a wide variety of overload requirements with standard lengths of 3.0 m and 3.25 m as well as custom special lengths on request. The precise design and proven technology of the GNA/GVA series guarantees reliable operation and minimal maintenance intervals.
