OverviewKongskilde grain suction blowers SUC and SupraVac provide pneumatic conveying solutions for farms and commercial grain operations. Available in electric and tractor PTO-driven versions, they handle grain pickup, silo loading/emptying, truck/wagon loading and in-field vacuum loading across a wide capacity range.
How grain suction blowers workThese units generate an airflow that draws grain into a suction cyclone where the grain is separated from the air. Grain is discharged via a rotary valve onto the pressure side pipeline for gentle horizontal, vertical and corner conveying, reducing damage and product loss.
Benefits- High transport capacity covering small mobile units up to the SupraVac 2000 for high-volume needs
- Choice of power: electric motor or tractor PTO to suit farm or site conditions
- Flexible pickup and conveying: field pickup, silo and on-floor storage handling with flexible piping
- Mobility options: trolley-mounted mobile units, three-point hitch and trailer types for field and road use
- Energy-efficient design and scalable connection to existing pipe systems
Models and key featuresSUC-E (Electric powered)Electrically driven SUC-E units are suited to indoor use and mobile trolley models. Common features include belt transmission protecting the drive, control cabinets for automatic operation and larger stationary variants for higher capacities.
- Typical models: SUC 100 E, SUC 150 E, SUC 200 E, SUC 300 E, SUC 500 E
- Capacities: mobile models up to ~33 t/h; stationary models up to ~64 t/h (larger available)
- Motor power examples (blower): 7.5 kW (10 hp) to 37 kW (50 hp)
- Mobile trolley versions for indoor/outdoor movement
SUC-T (Tractor powered, three-point hitch)SUC-T models are PTO-driven three-point hitch units for sites without electric supply. They feature compact design, automatic air control and an option for pressure feeding via direct rotary valve to increase capacity by ~20%.
- Typical models: SUC 300T, SUC 500T, SUC 700T
- Capacity examples: up to ~44 t/h depending on model
- Recommended tractor PTO power examples: 34 kW (45 hp) to 62 kW (85 hp)
SUC-TR (Tractor powered, trailer type)SUC-TR units are PTO-driven pull-type trailers designed for high-capacity loading and conveyance to storage. Standard loading equipment and tool-free belt tensioning facilitate field and transport use.
- Typical models: SUC 500TR, SUC 700TR, SUC 1000TR
- Capacity examples: up to ~64 t/h depending on model
- Recommended tractor PTO power examples: 48 kW (65 hp) to 90 kW (120 hp)
SupraVac 2000 (Tractor powered)SupraVac 2000 is the largest tractor-powered suction blower with very high capacity and a hydraulically operated folding truck load-out boom for fast loading of large vehicles. Optional transport boxes are available for suction heads and pipe components.
- Capacity: up to ~5,000 bu/h (≈120 t/h)
- Required power: approximately 170 hp PTO
- Features: hydraulic folding boom, easy pipe connection, optional transport boxes
