Cumberland Monocoque Fans

Variable-Speed Ventilation Fans for Poultry, Hog and Dairy Barns

The Cumberland Monocoque Fans are agricultural ventilation fans designed to provide efficient minimum ventilation performance in livestock and poultry facilities. Available in diameters from 12 to 24 inches, these fans feature an aerodynamic, one-piece hood, durable polypropylene propellers and variable-speed motor options to support controlled airflow in agricultural buildings.

Proper ventilation plays an important role in maintaining barn air quality, managing moisture and supporting consistent environmental conditions. Cumberland Monocoque Fans are engineered to reduce air turbulence, improve airflow performance and help protect ventilation components from demanding outdoor conditions.

For poultry, hog and dairy producers throughout Southwestern and Central Ontario, County Line Equipment offers Cumberland Monocoque Fans as an option for agricultural ventilation systems, barn upgrades and new construction projects.

Key Features & Benefits

• 12″ to 24″ Fan Diameters: Multiple sizes are available to accommodate different ventilation requirements.
• Variable-Speed Ventilation: Designed for minimum ventilation stages requiring controlled fan performance.
• Aerodynamic One-Piece Hood: Smooth corners help minimize turbulence and optimize airflow.
• Unrestricted Hood Airflow: The hood outlet is larger than the fan propeller diameter to reduce airflow restriction.
• Reduced Wind Interference: The hood outlet extends 7 to 9 inches from the building wall, depending on the model.
• Moisture Drainage Design: Slanted hood walls direct condensation outside the building to help prevent blade freezing.
• Impact-Resistant Hood Construction: The one-piece design helps resist impacts from snow and ice falling from the roof.
• Polypropylene Propellers: Durable, precisely balanced blades help reduce moisture condensation and freezing.
• Stainless Steel Hardware: Designed for long-lasting performance in agricultural environments.
• Corrosion-Resistant Safety Grill: Baked enamel finish provides additional protection.
• Multiple Motor Options: Available with Multi-Max or Marathon motors.
• Optional Shutters and Winter Covers: Accessories help adapt the installation to seasonal ventilation needs.

Durable Polypropylene Propellers

Cumberland Monocoque Fans feature polypropylene propellers designed for durability and precise balance.

The manufacturer matches propeller pitch and motor specifications to optimize airflow output and airflow efficiency.

The polypropylene construction also helps reduce moisture condensation and freezing on the blades.

This makes the fans suitable for livestock buildings where humidity and changing temperatures can affect ventilation equipment.
