FRP Negative Pressure Exhaust Fan for Livestock Farms

• Corrosion-resistant FRP fan housing
• Aerodynamic discharge cone for efficient exhaust
• FRP or stainless steel blade options
• Direct-drive and belt-drive configurations
• Wall-mounted installation for livestock houses
• Optional configurations for pit and roof ventilation applications

• FRP Corrosion-Resistant Housing: Fiberglass-reinforced plastic frame resists rust, moisture and corrosive gases commonly found in livestock environments.
• High-Volume Exhaust: Large axial fan structure supports rapid removal of heat, humidity, dust and stale air from livestock buildings.
• Optional Blade Materials: Available with FRP or stainless steel fan blades according to project requirements.
• Aerodynamic Discharge Cone: Guides exhaust airflow away from the building and helps improve overall fan performance.
• Direct or Belt Drive: Different transmission configurations are available for various farm ventilation projects.
• Stable Belt Tension: Belt-drive configurations can use an elastic tensioning mechanism to maintain consistent belt tension.
• Low-Maintenance Structure: FRP housing does not require the same anti-rust maintenance as conventional galvanized steel frames.
• Multiple Installation Options: Suitable configurations are available for sidewalls, manure pits and roof ventilation systems.

• Commercial pig houses
• Farrowing and gestation buildings
• Nursery and finishing barns
• Poultry houses
• Dairy and cattle barns
• Manure pit ventilation systems
• Livestock house roof ventilation
• Tunnel ventilation and cooling systems
• New farm construction and ventilation renovation projects

• Determine fan quantity and capacity according to livestock type, building dimensions, climate and required ventilation rate.
• Prepare a rigid and level wall opening or mounting frame according to the selected fan dimensions.
• Seal the perimeter between the fan frame and building structure to prevent uncontrolled air leakage.
• Keep sufficient clearance around the discharge cone and avoid structures that restrict exhaust airflow.
• Connect the motor according to the specified voltage, phase and electrical protection requirements.
• Inspect fan blades, guards, bearings, fasteners and motor connections periodically.
• For belt-drive models, check belt condition and tension regularly.
• Remove excessive dust, feathers and debris from blades and airflow passages to maintain ventilation efficiency.
• Keep pit-fan drainage and service areas accessible for cleaning and wastewater management.
• Disconnect and lock out electrical power before inspection, cleaning or maintenance.

Q: Why is FRP used for the fan housing?
A: FRP provides excellent resistance to rust, moisture and corrosive livestock-house gases, making it suitable for demanding farm environments.

Q: What blade materials are available?
A: The current product can be configured with FRP or stainless steel fan blades.

Q: What is the purpose of the discharge cone?
A: The cone guides discharged air away from the building, supports efficient airflow and can help reduce undesirable exhaust recirculation between nearby livestock-house openings.

Q: Is the fan available with direct drive or belt drive?
A: Yes. Both transmission types are available depending on the selected fan configuration and project requirements.

Q: Can the fan be used in pig houses?
A: Yes. It is designed for negative-pressure ventilation in pig houses and can also be used in poultry, cattle and other livestock buildings.

Q: Can it be installed for manure pit ventilation?
A: Yes. A dedicated pit-fan configuration with an anti-backflow structure and removable design is available for suitable projects.

Q: Can it be installed on the roof?
A: Yes. Roof configurations can use dedicated mounting components designed to reduce rainwater leakage and accommodate different farm-building requirements.

Q: How do I select the correct fan size and quantity?
A: Selection should be based on animal type, house dimensions, stocking density, local climate, ventilation mode and required airflow. Project-specific ventilation calculations are recommended.
