Direct Engine-Drive Fans Are a Versatile Ventilation Option

The Brock GUARDIAN® Series Low-Speed (1750 RPM) Centrifugal Fan is designed for direct engine-drive use. Use a flexible coupling to link this fan to irrigation and other utility engines.

Durably Built for Long Service Life

Durable Steel Housing
Reinforced heavy-duty galvanized steel housing offers durable and long fan life.

Adjustable Feet
Adjustable feet make it easy to level the unit on the fan’s foundation.

Heavy-Duty Shaft
A heavy-duty 2-inch (51-mm) diameter high-tensile steel drive shaft is designed to hold up under demanding conditions.

Double Pillow-Block Bearings
The industrial grade double pillow-block bearing configuration eliminates the need for a flanged bearing on the inlet side of the fan. This bearing configuration also prevents the reduction in air flow performance caused by locating a flange bearing on the inlet side.

Dynamically Balanced Centrifugal Wheel for Improved Air Flow

A dynamically balanced centrifugal wheel features advanced air foil blade design to help promote better air flows.

Reliable Control Box

A standardized control box is used with all Brock GUARDIAN® Series fans and heaters.

  • Controls are specifically matched to each fan or heater unit.
  • Control boxes are made of durable polycarbonate and include a hinged translucent cover.
  • The control housing is weather- and dust-proof and rodent-resistant.
  • Standard components are used for safe and reliable motor control.
  • Adjustable overload protection is included.
  • Brock heater controls use an industrial-design ignition transformer.
