BROCK Aeration Systems

Axial Fans

The BROCK Aeration System product line offers:

  • Economical GUARDIAN Series Vane Axial Aeration Fans with high air-flows at low static pressures.
  • Factory-balanced fans tested for vibration and energy usage to provide reliably smooth operation.
  • Recommended and optional BROCK Axial Wrap-Around and Bolted Fan Transitions to optimize air-flow into the grain.

The GUARDIAN Series Vane Axial Fan’s venturi opening uses innovative curvature design for efficient air performance. A 10-mil PVC coating on screen guard provides superior corrosion resistance and attractive appearance.

Air vanes are a standard feature on all 18-inch (457-mm) diameter and larger fans. The vanes aid efficient airflow at higher static pressures by reducing air turbulence.

Dynamically balances cast aluminum blade has advanced air foil design for efficient air handling.

Totally-enclosed, air over (TEAO) motors are standard for all GUARDIAN Series Axial Fans. Two-piece bolt-together motor mount/ fan support provides a solid connection for mounting the fan and aids fan stability during operation.

 

Centrifugal In-Line Fans

The BROCK Aeration System product line offers:

  • GUARDIAN Series Centrifugal In-Line Aeration Fans with low air-flows at high static pressures – excellent for use with smaller grain bins holding small grains (wheat, rapeseed, barley, etc.)
  • Factory-balanced fans tested for vibration and energy usage to provide reliably smooth operation.
  • Recommended BROCK Axial Wrap-Around Fan Transitions to optimize airflow into the grain.

Dynamically balanced aluminum centrifugal wheel features advanced air flow blade design to efficiently handle low air-flows at medium to high static pressures.

All BROCK GUARDIAN Series Centrifugal In-Line Fans feature a reinforced, 12-guage, galvanized steel housing for durability and long fan life.

Totally-enclosed, air over (TEAO) motors are standard for all Brock GUARDIAN Series Centrifugal In-Line Fans. Two-piece bolt-together motor mount/fan support provides a solid connection for mounting the fan and aids fan stability during operation. Air straightening vanes  aid efficient air flow by reducing air turbulence.

Fan’s air inlet orifice uses an innovative design to promote better airflow into the centrifugal wheel to enhance fan performance. The unique baffle design helps to direct air into the centrifugal wheel to encourage smooth, efficient fan operation. A 10-mil PVC coating on screen guard provides an attractive appearance and superior corrosion resistance.

Low-Speed Centrifugal Fans

The BROCK Aeration System product line offers:

  • GUARDIAN Series Low-Speed Centrifugal Aeration Fans with high air-flows at medium static pressures for larger storage bins.
  • Factory-balanced fans tested for vibration and energy usage to provide reliably smooth operation.
  • Recommended and optional BROCK Centrifugal Wrap-Around and 44-and 67-inch (1118- and 1702-mm) Wide Bolted Fan Transitions to optimize airflow into the grain.

All Brock GUARDIAN Series centrifugal fans have a reinforced, 12-guage, galvanized steel housing for durability and long fan life. Totally-enclosed, fan cooled (TEFC) motors are standard.

When GUARDIAN Series Centrifugal Fans require a foot-mount, Brock’s high-strength adjustable foot structure with dampening pad assists with leveling the unit and provides the fan support needed for smooth operation.

As a part of Brock’s high standard of quality and reliability, all GUARDIAN Series Centrifugal Fans are factory-tested for fan balance to minimize performance-robbing vibration.

A Variety of Ways to Support GUARDIAN Series Centrifugal Fans:

  • The BROCK Aeration System offers a variety of approved mounting options for installing GUARDIAN Series Centrifugal Fans and transitions to BROCK Grain Storage Bins. Each has been designed and tested to ensure proper fit and smooth performance.
    • Knee-Brace Mount
    • Cable Suspension Mount
    • Concrete Foundation Mount

High-Speed Centrifugal Fans

The BROCK Aeration System product line offers:

  • GUARDIAN Series High-Speed Centrifugal Aeration Fans with low air-flows at high static pressures.
  • Factory-balanced fans tested for vibration and energy usage to provide reliably smooth operation.
  • Recommended BROCK 44-inch (1118-mm) Wide Bolted Fan Transitions to optimize airflow into the grain.

The GUARDIAN Series High-Speed Centrifugal Fan’s air inlet orifice uses an innovative design to promote better airflow into the centrifugal wheel to enhance fan performance. A 10-mil PVC coating on the screen guard provides superior corrosion resistance and attractive appearance.

Diverter and baffle help to redirect air spilling from the centrifugal wheel to encourage smooth, efficient fan operation. Dynamically balanced, seam-welded steel centrifugal wheel features advanced air foil blade design to help maximize air performance.
