PMR Grain Solutions

Fans

The demands of farming are never-ending. Maintaining consistent grain quality is essential to long-term profitability and viability. GSI manufactures a complete line of aeration and grain-conditioning systems to help maintain grain quality in any operation.

Never satisfied with the status quo, for over 40 years we have been driven to provide top-of-the-line products that will protect, condition and move the grain you work so hard to produce. As the pioneers in grain conditioning, we’ve set the industry standard with forward-thinking solutions designed to make you more productive.

The quality of our products is only matched by our commitment to stand behind them. Every component we design and produce is pretested before installation to ensure your system is running at optimal performance. We are committed each and every day to provide the best products and service possible. Our industry experts, and our worldwide network of dealers have provided farming operations with unparalleled expertise and support for over 40 decades.

While our commitment to remain at the top runs deep, our commitment to you runs even deeper.

VANE AXIAL FANS

For application requiring high airflow at static pressures below 6” (depending on bin diameter), GSI offers vane axial fans in 12” diameter (1 HP) through 28” diameter (15 HP). Vane axial fans 18” and smaller use cast aluminium blades. Vane axial fans 24” through 28” use durable composite airfoil blades that are lightweight for easy starting and function well in this type of environment.

The 12” through 28” (1-15 HP) units feature a 3450 RPM motor for increased fan performance and energy efficiency. Close fan blade tip clearance and straightening vanes provide maximum airflow and reduced turbulence to ensure smooth and consistent airflow.

All 24” and 28” vane axial fans also include a durable plastic inlet venturi which funnels air more efficiently into the fan.

INLINE CENTRIFUGAL FANS

Aeration jobs at high static such as with milo, wheat or rape seed require special consideration. Aerating tall hopper tanks presents another challenge. The inline centrifugal fan is designed to handle both of these applications effectively.

Suited for higher static pressures, beyond the performance range of vane axial fans, the inline centrifugal fan offers higher static pressure capabilities than a 1750 RPM centrifugal fan at a lower cost.

Inline centrifugal fans make less noise than vane axial fans at 3500 RPM due to the fan wheel being totally enclosed in the fan housing.

Inline Centrifugal cannot be used with heaters due to their design.

1440 RPM CENTRIFUGAL FANS

GSI's 1440 RPM centrifugal fans are built with a heavy galvanized steel, scroll-type housing and inverted inlet venturi. A non-overloading backward- inclined airfoil wheel provides high air flow with a long motor life. These fans operate at a very low noise level and are designed to accommodate a variety of heaters for use on drying bins where higher capacities are required. Models are available from 5 - 50 HP with static pressures up to 11".

2900 RPM CENTRIFUGAL FANS

GSI also manufactures a 2900 RPM centrifugal fan designed to operate in static pressures up to 22". These fans are used primarily with tall tanks or small grains tanks with high resistance to airflow. 2900 RPM centrifugal fans cannot be used with heaters due to their design.
