Specification

1.Strong corrosion resistance: Galvanized sheet has excellent rust and corrosion resistance, suitable for places with high corrosiveness such as humid and hot environments or chemical industries, extending the service life of fans.

2.High strength: The galvanized sheet material is sturdy and durable, capable of withstanding large external impacts, ensuring that the fan remains stable in harsh working environments.

3.High ventilation efficiency: Negative pressure fans use the principle of negative pressure to quickly remove indoor heat, exhaust gas, and dust, effectively improving ventilation and air exchange effects, especially suitable for large-scale factories and greenhouses.

4.Energy saving and environmental protection: Negative pressure fans are usually installed on walls or roofs, utilizing natural wind power and outdoor air flow to form convection, reduce energy consumption, and achieve energy-saving effects.

5.Low noise design: The negative pressure fan has been optimized for smooth operation and low noise, making it suitable for workplaces with high environmental noise requirements.

6.Easy installation and maintenance: Due to its light weight and simple structure, the galvanized sheet negative pressure fan is easy to install and has lower maintenance costs.

Application of the greenhouse

1. Industrial plant In large factories and workshops, galvanized sheet negative pressure fans can quickly exhaust hot air, smoke,and harmful gases, keeping indoor air fresh. Especially suitable for factories in high-temperature or dusty environments such as mechanical manufacturing, textiles, electronics, etc.

2. Livestock farms Temperature and air quality control are often necessary
in livestock farms. Galvanized negative pressure fans can quickly eliminate polluted air, reduce indoor temperature, prevent harmful gases from affecting animal health, and improve the comfort of the breeding environment.

3. Greenhouse In agriculture, it is often necessary to maintain good ventilation inside greenhouses to promote crop growth. Galvanized sheet negative pressure fan helps regulate the temperature and humidity inside the greenhouse through effective ventilation, avoiding damage to plants due to high temperature or humidity.

4. Warehouse and logistics center For some warehouses storing items such as flammable and explosive materials or items that require low-temperature storage, galvanized sheet negative pressure fans can quickly ventilate and maintain air circulation in the warehouse, reducing the risk of temperature rise.

5. Public facilities Large space venues such as stations, exhibition halls, and sports centers use galvanized negative pressure fans to ensure air flow, improve air quality, and enhance environmental comfort.

6. Chemical plants and heavily polluted environments In places with high emissions of harmful gases such as chemical plants, dye factories, and pharmaceutical factories, galvanized sheet negative pressure fans can efficiently discharge exhaust gas and smoke, prevent harmful substances from accumulating indoors, and ensure the health and safety of
workers.

7. Tunnels and basements In places with poor ventilation conditions such as tunnels or underground buildings, galvanized sheet negative pressure fans can effectively facilitate air flow and exchange, preventing the accumulation of harmful gases.

8. Large kitchens and catering industry Used for ventilation in high temperature environments such as large kitchens and canteens, it can quickly remove oil fumes and heat, and improve the working environment.
