Permanent Lagnet Variable Frequency Fan

Built-in high-performance rare earth EC motor, using neodymium-iron-boron (NdFeB) magnetic material with a magnetic force of up to 3500 Gauss. This means the fan has stronger power, and the magnetic decay during long-term use is extremely low, ensuring the fan's performance does not degrade throughout its entire lifecycle.

The voltage input range covers 300V-450V, perfectly adapting to the unstable grid environment in rural areas or farms. Without additional voltage stabilization equipment, the fan can automatically adjust its operating status to avoid shutdowns or damage caused by voltage fluctuations.

The motor and key components meet the IP66 protection standard. The fully enclosed structure effectively blocks corrosive gases, dust, and water vapor inside the pig house from entering the interior. This greatly extends the motor's lifespan, prevents corrosion of coils and bearings, and reduces maintenance frequency.

Even under low load (low speed) operation, the energy efficiency remains above 75%, while ordinary AC motors are only around 40%. This is particularly amazing for pig houses that require 24-hour minimum ventilation, offering incredible energy-saving effects.

Supports stepless speed regulation, ensuring a uniform and smooth transition of air volume without any jerkiness. The soft start function eliminates the current surge during startup, protecting the motor and the power grid, while also reducing stress on the pig herd.

Equipped with automatic protection functions for high temperature, overload, and overcurrent. When the environment is abnormal or the fan is obstructed, the system will automatically adjust the speed or shut down for protection. There is no need for external complex circuit breakers or contactors, reducing electrical installation costs.

Paired with a precisely calculated aerodynamic blade design, it features low wind noise, large air volume, and high wind pressure. It ensures sufficient airflow is generated even at low speeds to maintain fresh air inside the pig house.

The overall structure is compact, making installation and maintenance convenient. The corrosion-resistant fiberglass or high-strength plastic housing is not only lightweight but also resistant to acid and alkali corrosion, making it highly suitable for high-humidity cleaning and disinfection environments.

Thanks to the electronic commutation technology of the EC motor, the operating noise is significantly lower than traditional brushed motors or AC motors. It provides a quiet resting environment for the pigs, reduces noise stress, and promotes growth.

Can seamlessly connect with various environmental controllers (0-10V or 4-20mA signals) to achieve precise closed-loop control of temperature and humidity in the pig house, making it an ideal choice for intelligent farms.
