Qingdao City, Shandong Province, China – September 7, 2026 – In modern livestock and poultry farming, ventilation is a critical factor determining animal health and production efficiency. Recently, a 50-inch FRP (Fiberglass Reinforced Plastic) cone fan designed specifically for farming environments has attracted industry attention; thanks to its FRP construction, conical design, and direct-drive mechanism, it is emerging as a preferred ventilation solution for facilities such as pig barns and poultry houses.

Addressing Key Farming Challenges: Ammonia Corrosion and Equipment Longevity

Livestock and poultry houses often contain high concentrations of ammonia (NH₃), hydrogen sulfide (H₂S), and moisture; standard galvanized steel fans typically rust and deteriorate within one to two years in such environments. In contrast, FRP offers excellent corrosion resistance, withstanding atmospheric exposure, water, and common concentrations of acids, alkalis, and salts. Both the housing and blades of this fan are made from high-strength, anti-corrosive FRP; the thickened design ensures superior waterproofing and outstanding aging resistance. The housing is manufactured using a one-piece FRP molding process, resulting in a unit that is lightweight, electrically insulating, rust-proof, and resistant to aging, chemicals (acids/alkalis), temperature extremes, and moisture. This robust construction significantly extends the fan’s service life.

Conical Design: Higher Airflow and Efficiency

Compared to traditional square fans, the conical outlet design significantly boosts airflow output. This 50-inch fan features a propeller diameter of 1,250 mm and delivers an airflow of up to 44,000 m³/h (approximately 26,000 CFM), with some models reaching as high as 45,000 m³/h. Optimized using aerodynamic principles, the conical fan design ensures high airflow, low noise, and high efficiency. The PVC shutters are designed for smooth airflow; they operate without electricity or manual switching while effectively preventing rainwater ingress.

Direct Drive: Maintenance-Free and Durable

The fan utilizes a direct-drive system where the motor connects directly to the blades. This simple structure eliminates the need for maintenance, improves sealing, minimizes airflow loss, and removes the need for belt replacements, resulting in a service life of over 10 years. Motors are available from renowned domestic brands as well as international brands such as Siemens, ABB, and WEG; featuring an IP55 protection rating and Class F insulation, they ensure stable operation in harsh environments.

Wide Range of Applications: From Poultry Houses to Pig Barns

FRP cone fans are widely used for ventilation and cooling in agricultural and industrial settings, particularly in livestock farming, poultry houses, and greenhouses. In poultry houses, they rapidly exhaust ammonia, moisture, and stale air; in pig barns, they effectively remove harmful gases and heat. When paired with evaporative Cooling Pads, they can lower indoor temperatures by 5–10°C. The large 50-inch diameter design is particularly well-suited to the negative-pressure ventilation requirements of large-scale farms.

Industry Trend: High-Quality Ventilation Equipment Becomes Essential

As the domestic livestock industry shifts toward large-scale, intensive operations, farmers are increasingly demanding higher-quality ventilation equipment. Thanks to their combined advantages of corrosion resistance, high airflow capacity, and long service life, FRP fans are gradually replacing traditional metal fans. The 50-inch FRP cone fan is emerging as the preferred choice for ventilation upgrades in modern farms.
