Brock’s GUARDIAN® Series Double-Wide Double-Inlet Centrifugal Fan
Belt-drive operation offers quieter (3 dB less), smoother fan operation with less vibration compared to direct drive single inlet fans. It also makes drive system maintenance easy. (The fan safety guard has been removed to show the belt drive in this photo.)
Fan motor mounts on transition housing to eliminate the typical added suspension needed for the motor along with potential strain on fan motor bearings. Future fan motor upgrades to higher horsepower are also easier.

GUARDIAN® Series DWDI Fans
Why consider a GUARDIAN® Series Double-Wide, Double-Inlet (DWDI) Centrifugal Fan for grain bin aeration? The Brock DWDI fans offer:
- High efficiency.
- Lower noise.
- Requires less energy than single-inlet fans to generate the same airflow volume.
Brock's GUARDIAN® DWDI Centrifugal Fans promote uniform, efficient air movement into the grain bin. The double-wide double-inlet unit also offers easy access to motors for servicing as needed. This fan has the added advantage that the same motor can be used for both high-speed and low-speed fan options.
Brock's DWDI fans provide:
- Choice of low-speed or high-speed models.
- Choice of 30-, 40- or 50-horsepower motors.
- Low-speed fan models with high airflows at low to medium static pressures for larger storage bins.
- High-speed fan models with low airflows at high static pressures for more efficient aeration of tall stored grain heights.
Factory-balanced centrifugal wheels provide smooth, efficient fan operation aided by Brock’s cable suspension mounts for hanging fans from the bin’s sidewall. Cable suspension makes it easier to clean under the fan and is 50% less than the cost of a concrete foundation. Concrete foundation option is available.
These Brock Fans are Variable-Frequency Drive (VFD) capable. They may be used with a VFD to help provide more precise control of the fan’s speed and energy consumption.
