Pneumatic Conveyors
Suction Blowers – SUC and SupraVac
Kongskilde’s grain suction blowers, including the SUC and SupraVac series, offer powerful and flexible solutions for conveying grain in both indoor and outdoor settings.
These systems are designed to efficiently handle grain by moving it through pneumatic conveying, which is ideal for farms and commercial operations needing to move grain from silos, on-floor storage, or directly into trucks or grain wagons.
With both electric and tractor-powered options available, these blowers meet a wide range of operational capacities and flexible requirements.
How Grain Suction Blowers Work
Grain suction blowers work by creating a powerful airflow that sucks grain into the system through a suction cyclone, where the grain is separated from the air. The grain then passes through a rotary valve and is deposited into a pipeline on the pressure side of the blower. This system allows for the efficient and gentle movement of grain horizontally, vertically, and around corners, minimizing damage and loss during transport.

Benefits of Kongskilde Grain Suction Blowers
- High Transport Capacity: Models like the SupraVac 2000 can handle up to 5,000 bushels per hour (120 tons/hour), making them suitable for high-volume needs.
- Choice of power source: Electric and PTO-driven models suit different sites. Tractor-powered models can also operate where electric power is unavailable.
- Flexible pickup and conveying: Pick up grain in fields, silos, or on-floor storage, then move it horizontally, vertically, and around corners. Flexible pipes help reach the grain without fixed infeed equipment or a specific building or grain-pit layout.
- Mobility: Tractor-driven models are easily transportable, allowing for flexible use across various parts of the farm, in-field or in a storage facility.
- Efficient Design: Designed to minimize energy usage while maximizing output, ensuring cost-effective operation.
- Room to increase capacity: If requirements grow, a larger suction blower can be connected to the same pipe system.
SUC-E, SUC-T, SUC-TR, and SupraVac 2000 Suction Blowers
The SUC E is the electrically driven Grain Vac/Suction Blower. SUC-T, SUC-TR, and SupraVac 2000 are all tractor-driven. SUC-T is lift mounted, and SUC-TR and SupraVac 2000 are trailer types. All three models offer the possibility of maximum mobility together with high capacity. Furthermore, SupraVac 2000 offers a hydraulically operated truck load-out boom that can fold and unfold for road transport.
SUC-TR
Tractor Powered

The SUC-TR models are pull-type PTO-driven grain vacs that can be used to load trucks or grain wagons directly from the on-floor storage, silos or grain bins. They can also be used to convey commodities to storage where high-capacity conveying is required.
- Capacity up to 64 t/h.
- The trailer models are powered by the tractor’s PTO shaft.
- Loading equipment is standard on SUC-TR models.
- Ideal for loading trucks and trailers.
- Belts can be tightened without using tools.
- Available models of the SUC-TR grain vac: SUC 500TR, SUC 700TR, SUC 1000TR
SupraVac 2000
Tractor Powered

The SupraVac 2000 has a capacity of up to 5,000 bu/h (120 t/h), making it the ideal grain vac for farmers and commercial users. It has a hydraulic-folding truck loading boom that allows for quick setup. It conveniently locks into place for transport and storage.
- Capacity up to 120 t/h.
- Our largest tractor-powered suction blower.
- The power takeoff-driven SupraVac 2000 requires 170 hp.
- Loads even the largest vehicles quickly.
- Hydraulic folding of loading equipment to transport position.
- Easy connection of pipe system.
- Optional transport box for the suction head and pipe components.
SUC-T
Tractor Powered

The SUC-T models are three-point hitch PTO-driven grain vacs. The blowers can be used to convey commodities to where high-capacity conveying is required and when no electrical power source is available.
- Capacity up to 44 t/h.
- Attached to the tractor’s three-point linkage.
- Automatic air control is standard on the SUC-T.
- Available without suction equipment for pressure conveying, providing up to 20% more capacity with direct rotary valve feeding.
- The compact design makes it easy to maneuver.
- Available models of the SUC-T grain vac include: SUC 300T, SUC 500T, SUC 700T
SUC-E
Electric Powered

SUC E is the electrically driven Suction Blower, ideal for indoor use where tractor-powered units are not an option. Smaller SUC E models are mounted on a trolley and can therefore easily be moved from place to place.
- Capacities up to 33 t/h on mobile models, and up to 64 t/h on stationary models.
- Larger stationary models are available for higher capacities.
- Mainly used for grain conveying inside buildings.
- On wheels and easy to move.
- Control cabinet for automatic starting/stopping the motor.
- Belt transmission protects the drive of both blower and rotary valve.
- Available models of the SUC-E grain vac include: SUC 100E, SUC 150E, SUC 200E, SUC 300E, SUC 500E
