Airstorm Fiberglass Fans

GrowerSELECT AirStorm Fans

GrowerSELECT’s AirStorm fiberglass fans deliver superior ventilation performance to producers who demand the best value. AirStorm fiberglass fans are key components in designing efficient swine and poultry ventilation systems.

We took 45 years of construction knowledge and applied it to designing ventilation fans that perform on our customers' farms. AirStorm fans are refined and tested using our in-house wind tunnel, and their performance ratings and specifications verified by BESS Labs.

  • Our fiberglass fans are manufactured from corrosion resistant components to withstand the harshest production and weather environments
  • We regularly test CFM ratings from production fans, the same ones we deliver to your farm, ensuring consistent reliability you can count on
  • Matched motor and blade combinations deliver dependable, consistent air flows in a full range of static pressure ratings

Variable Frequency Drive (VFD) Fans

All AirStorm X-Brace Series and 14” - 36” fiberglass exhaust fan models are available with optional VFD motor/drive combinations installed from the factory. Add-on kits* can also be purchased for and installed on existing fans already in the field.

  • A fan controlled by Variable Frequency Drive (VFD) uses a three-phase, single-speed motor. A VFD controller receives a 0-10V signal from the house controller and generates a corresponding signal to the fan motor in frequency, or hertz.
  • Using hertz to control fan speed has significant advantages over traditional voltage control using triacs, including less motor overheating and improved energy efficiency.
  • A VFD fan can operate from full-delivery down to nearly zero-speed. This CFM range allows producers to replace several existing smaller minimum ventilation fans with a single larger VFD fan that can operate covering minimum ventilation needs during winter all the way to tunnel fan performance in the summer.
  • *See page 6 of the Swine Ventilation Systems Booklet for more information about our VDF kits.

X-Brace Series

Our “Farm Smart” X-Brace design improves fan lifespan and performance while reducing maintenance downtime and costs. These fans were designed putting an emphasis on using corrosion resistant materials while also delivering improved CFM performance under standard operating static pressures required in modern hog and poultry barns.

The 54" & 51" X-Brace model fans are a through-wall mount design with a gel coated white fiberglass housing, optional poly discharge cone* and an improved plastic vane shutter. (*Poly discharge cone sold separately, items # AS-54206 & AS51206)

The 57" X-Brace model fan is a flush-wall mount design* with a gel coated black fiberglass housing, black poly discharge cone and corrosion resistant poly butterfly shutter. (*Optional stainless steel mounting kit available to adapt fan to a through-wall installation, item # AS-57FMH)


Rigid X-Brace Support
  • Constructed of aluminum tubing with blue epoxy coating and triangle edge profile to reduce wind turbulence
  • X-Brace design moves anchor points to cushioned rubber frame mounts in the fiberglass housing corners to provide maximum rigidity and reduce vibrations
  • Stainless steel motor and shaft bearing mount with stainless steel hardware provides a stable, corrosion resistant platform for the 1.5 HP GrowerSELECT fan motor

Improved Shaft Bearing
  • New, solid base pillow block shaft bearing housing provides a more stable shaft mount while reducing vibration
  • New shaft bearing features double-lip FloBack seal to reduce the possibility of being pushed out by over-lubricating
  • FloBack seal reduces outside contamination from dust and increases lubrication by directing grease back toward the balls and raceways during operation, extending bearing life

Flat Performance Curve
  • Proprietary stainless steel prop configured for peak air delivery at typical operating static pressures
  • Most efficient CFM ratings between 0.05” and 0.15” W.C. static pressures

Efficient Drive System
  • Powered by a GrowerSELECT 1.5 HP high service factor (1.5 SF @ 60 Hz) motor
  • Self-adjusting tensioner automatically keeps the 1/2" link belt at the proper tightness for maximum efficiency

Low Maintenance Shutter (54" & 51" X-Brace fans)
  • Constructed with a heavy PVC frame, reinforced corners and a generous 1” flange
  • PVC vanes feature true airfoil pattern
  • Spring steel rods extend the entire length of the shutter with unique lockdown ends

Poly Butterfly Shutter (57" X-Brace fan)
  • Corrosion resistant poly dampers seal tight with magnetic closures and dual tension springs
  • Aluminum damper ring maintains maximum stability in any temperature extreme

Quality Components
  • Fiber-resin props offer outstanding performance and in any environment
  • High service factor motors provide protection from problems caused by varying incoming electrical voltage
  • All fans feature energy efficient GrowerSELECT drive motors
  • White PVC shutters feature full-length spring steel rods, instead of plastic pins, locked into a heavy PVC frame with reinforced corners

Improved Performance
  • One inch shaft rides on permanently lubricated ball bearings that resist damage from dust and moisture contamination
  • Optional polyethylene cones help increase performance by improving total CFM airflow (cones available for all 3 sizes)

Infinity Direct Drive Fans

Built on the rugged X-Brace platform; Hog Slat’s Infinity fan line incorporated advanced motor technology to increase efficiency and energy savings. Brushless DC motors utilize integrated electronics that convert AC power to DC, calculate the house controller signal and control fan speed by regulating the power to the motor. Infinity fans have several significant advantages including:

The Infinity drive unit regulates fan speed to maintain environmental conditions inside the barn.

  • Precise variable speed output. Upon receiving a signal from the house controller, the motor microprocessor determines the correct speed for the desired ventilation rate. It continually monitors the fan shaft’s RPMs and adjusts the power inputs to maintain the correct speed.
  • Reduced maintenance. The direct-drive motor design eliminates shaft bearings, pulleys and belt: no more costly and time-consuming repairs and adjustments
  • Lower energy costs. At full-load the Infinity motor is 10% more efficient than conventional AC motors. The Infinity motor maintains its high-efficiency even at lower fan speeds.
  • Extended motor life. Infinity motors operate at cooler temperatures than comparable voltage-controlled AC motors, even at slower speeds. High operating temperatures are one of the leading causes of motor failure.
  • Fewer fans. Infinity fan’s ability to operate effectively at low airflow rates means there is no need to use smaller, less efficient fans for minimum ventilation requirements.
