Below is the product introduction for fiberglass negative pressure fans used in animal farming:

- Working Principle: When the fan operates, it extracts indoor air, reducing indoor air pressure and creating a negative pressure zone. Due to the pressure difference between indoors and outdoors, outdoor air flows into the room through natural openings (such as doors and windows), forming air convection. This achieves functions like ventilation, air exchange, and cooling.
- Product Features: Excellent corrosion resistance, capable of withstanding various corrosive substances in farming environments; typically offers high air volume, enabling rapid expulsion of indoor stale air—for example, the FansTech Livestock Farming Fiberglass High Negative Pressure Fan MPF36 can achieve an air volume of up to 25,800 m3/h; low energy consumption during operation, helping farmers save costs; relatively low rotational speed, resulting in minimal noise and reduced disturbance to farm animals; long service life—models equipped with fully sealed bearings from Dutch UBC and New Zealand NSK require no lubrication and are robust and durable.
- Material and Structure: The housing is made of fiberglass, offering high strength, lightweight, corrosion resistance, and good insulation properties; fan blades are typically made of high-strength, wear-resistant materials such as nylon, with optimized angle and shape designs to ensure efficient air exhaust; usually equipped with high-quality motors for stable power, some models also feature intelligent control systems, waterproof and dustproof designs, and adjustable fan speed as optional accessories.
- Application Scenarios: Suitable for various types of farms, such as pig farms, chicken farms, and cattle farms, to eliminate foul odors from animal waste, improve the farming environment, and enhance breeding efficiency; also applicable for horticultural greenhouses, providing optimal ventilation and cooling conditions for plant growth.
