Q1: What is the primary application of the FJS-II fan?
A1: It is designed for large-scale ventilation and cooling in industrial facilities, warehouses, greenhouses, and livestock farms.

Q2: How does the negative pressure ventilation work?
A2: The fan creates negative pressure inside the building, drawing in fresh air from openings, which provides effective cooling and air exchange.

Q3: Why is this fan made of FRP?
A3: The fiberglass composite material provides excellent corrosion resistance and anti-aging properties, making it ideal for humid or corrosive environments.

Q4: Does the fan require maintenance?
A4: It has minimal maintenance requirements, with a simple design and easy access for cleaning the impeller and louvers.

Q5: Can the fan operate in wet conditions?
A5: Yes, the weatherproof fiberglass construction and automatic louvers allow it to operate in high humidity and rain.

Q6: What are the operating limits for temperature and humidity?
A6: The maximum gas temperature is 60°C, and it can operate in high humidity environments up to 100% relative humidity.

Q7: Is this fan suitable for continuous operation?
A7: Yes, it is designed for 24/7 continuous operation with low noise and vibration.

Q8: How do I select the right model for my project?
A8: Select based on your required airflow (m³/h) and the size of the space. Our technical team can help you choose the best model based on your specific application.

Q9: Can the fan be installed in a window opening?
A9: Yes, the compact square design is ideal for installation in standard wall or window openings.
