|Cyclone Pneumatic Grain Moving System
Sukup Air Systems
Why a Pneumatic System?
A pneumatic (air) system is the ideal grain conveying system for new and existing
drying operations. This type of system is especially well-suited to moving grain from
a continuous flow dryer into cooling and/or storage bins.
An air system also gives you flexibility that you can’t get with traditional augers or
legs. You can easily direct grain to multiple bins from one location, even around
corners and into areas that would be difficult to reach with a transfer auger. An air
system also makes expanding your system simple - to include more bins, just add
The Sukup Cyclone Pneumatic System is made up of heavy-duty, industrial-grade
components and easy-to-use controls. The Sukup Cyclone is designed to give you
years of trouble-free operation and is backed by Sukup’s dedication to customer
service and a one-year warranty.
Standard Cyclone System Components
The Rotary Airlock used on Sukup Cyclone Systems is heavier and built better than
any other available, resulting in longer life. The thicker vanes eliminate the need for
adjustable tipped vanes.
Positive displacement pumps and electric motors with shielded belt drive provide the
air pressure for Sukup Cyclone Systems. Blower components are mounted on a
heavy-duty, galvanized skid. An industrial air filter on the blower cleans the air entering
the system. A filter restriction gauge lets you know when the filter needs to be cleaned.
The Sukup Control Box features a digital ammeter, which is more accurate than
analog meters. Other controls include; start/stop, fault indicators, and pressure
gauge. A time delay clears grain from the system after the fill auger shuts down.
Dual Motor Drive option gives you up to 30 horsepower, even in areas where only
single phase power is available.
A deadhead uses an expansion chamber to remove grain from the air stream. It can
be moved away from the fill hole to allow you to fill the bin with an auxiliary auger.
Galvanized 30" Dia. Cyclone is lined with long-lasting UHMW to protect the grain as it
decelerates. The large diameter handles larger volumes of grain with less wear.
Compensator Valve maintains consistent line pressure to prevent grain damage.
Pre-Cleaner extends filter life by removing up to 85% of dirt from the air before it
enters the filter.
Telescoping Cam-Lock System allows you to quickly and easily route grain to other
Adapter Kit attaches the airlock to your Sukup Dryer.
7-Way Distributor Valve routes grain to up to seven bins quickly and easily. Can be
mounted horizontally or vertically. When mounted in the vertical position, the valve is
operated from the bottom.
60 and 90 Degree elbows are designed with straight ends for better connections and
less grain damage.
Power Distribution Block ready to accept incoming power and provide complete
motor and circuit protections is available as a control box option.
Sight Glass allows you to monitor grain flow and velocity.
Offset Tube is useful for getting around obstacles and when routing tube
Pneumatic System Operation
A pneumatic system is a convenient, efficient way to move grain; however, attention must be given to maintain grain quality.
This is true with any pneumatic grain moving system.
The key to minimizing grain damage is controlling the velocity of the grain. If grain is moved to fast, it will be damaged.
Grain speed is regulated by air pressure. Contrary to what you may think, the higher the pressure, the slower the gain
moves, and the less damage that will occur. A rule of thumb is to have at least 3 psi of line pressure and to frequently check
the quality of grain that is being discharged into storage.
Make sure that tubing is properly installed and aligned and that the airlock is turning in the correct direction to utilize shear
protection (counter clockwise when looking at the non-drive end of the airlock). Following these general rules of operation
will help maintain grain quality. Refer to your Sukup Cyclone installation/operation manual for additional guidelines.
