- Large-scale Swine Housing Ventilation Systems: Protective guards for negative-pressure/positive-pressure fans in finishing barns, nursery barns, gestation barns, and farrowing barns.

- Livestock and Poultry Farming Ancillary Equipment: Fan safety guards for poultry houses, cattle barns, sheep sheds, and other breeding facilities.

- Livestock Farm Ancillary Buildings: Protective guards for ventilation fans in feed mills, manure treatment facilities, and warehouses.

- Agricultural/Industrial Ventilation Equipment: Protective mesh guards for air exchange fans in greenhouses and factory workshops.

1. Corrosion-Resistant and Weather-Resistant: Adapted for the Harsh Environments of Swine Farms

Constructed from hot-dip galvanized steel or 304 stainless steel, it resists corrosion from manure and disinfectants. It does not rust or become brittle, offering a service life 3 to 5 times longer than ordinary iron wire mesh, and maintains its shape even after prolonged use.

2. High-Efficiency Protection: Ensuring the Safety of Equipment and Livestock

The precision mesh design effectively prevents rodents, birds, and debris from being drawn into the fan, while ensuring airflow remains largely unobstructed to maintain ventilation efficiency. It also prevents livestock limbs from coming into contact with fan blades, thereby eliminating safety hazards. 3. Robust Construction: Wind- and Pressure-Resistant

Featuring thickened steel wires and a welded frame structure, this guard offers high wind resistance. It effectively withstands strong air currents and external impacts within the farm environment, ensuring stability and durability without easily deforming or dislodging.

4. Smooth Ventilation: Maintains Air Exchange Efficiency

The scientifically designed mesh layout minimizes airflow resistance, maximizing the fan's original ventilation capacity. This prevents issues such as uncontrolled temperature and humidity levels within the barn—problems often caused by overly dense protective screens.

5. Easy Installation, Cleaning, and Maintenance

With standardized dimensions, the guard can be quickly and seamlessly fitted to a wide variety of fan models. The snap-lock and bolt-fastening design facilitates easy assembly and disassembly, simplifying routine cleaning of dust and debris while reducing the risk of disease transmission.

6. Flexible Customization: Compatible with All Fan Types

We offer flexible customization options—including dimensions, materials, and mesh density—tailored to specific fan models and installation environments. This ensures that the unique protection requirements of different pig farms are fully met.
