The core advantages of large exhaust fans (including industrial ceiling fans/negative pressure fans) are wide coverage, uniform airflow, strong ventilation, energy saving and low noise, durability and easy maintenance, suitable for large spaces such as factories, warehouses, and venues.
1、 Oversized coverage, three-dimensional ventilation throughout the entire area
Wide coverage area: The 7.3-meter diameter model can cover up to 1500-2000 square meters per unit, equivalent to 50 ordinary small fans.
Three dimensional circulation without dead corners: Low speed (≤ 50rpm) pushes a horizontal airflow layer 1-3 meters high, forming a three-dimensional circulation from top to bottom+horizontal flow, solving the problems of heat accumulation at the top and moisture at the bottom of tall spaces.
High ventilation efficiency: ≥ 5 air changes per hour, far exceeding traditional fans (2-3 times) and natural ventilation (0.5-1 times).
2、 Effective cooling, comfortable and natural feeling
Sensory cooling of 5-8 ℃: accelerates sweat evaporation, simulates natural gentle breeze, without the discomfort of traditional fan strong wind blowing directly.
Temperature and humidity balance: The airflow in the entire area is evenly mixed to avoid local supercooling/overheating, reducing air conditioning load by about 30%.
3、 Energy saving and low long-term operation and maintenance costs
Ultra low power consumption: With a power of only 1.1-1.5kW, it consumes about 1 kWh per hour, saving more than 70% energy compared to air conditioners and 90% energy compared to traditional small fans.
Variable frequency speed regulation: Permanent magnet synchronous motor+variable frequency control, adjust the speed according to demand, and run at low speed more energy-efficient.
Short investment payback period: The equipment investment for a 1000 square meter factory is about 10000 yuan, and it usually takes 6-12 months to recoup the cost through energy saving.
4、 Low noise, durable, stable, reliable, and easy to maintain
Quiet operation: precise dynamic balance+low-speed design, full load noise ≤ 50dB (A), does not affect production and office.
Ultra long lifespan: Aluminum magnesium alloy fan blades+fully enclosed motor, designed for a lifespan of over 15 years, almost maintenance free.
Material anti-corrosion: The negative pressure fan adopts a galvanized sheet/stainless steel frame, which is corrosion-resistant, anti-aging, and suitable for humid/dusty environments.
5、 Multi functional adaptation, improving comprehensive environmental indicators
Dehumidification and mildew prevention: Accelerate air circulation, reduce storage humidity, and prevent goods from rusting and moldy.
Dust and odor removal: disperses dust, oil fumes, and odors, improves workshop air quality, and enhances the working environment.
Flexible installation: can be lifted/wall mounted, suitable for heights above 4 meters, and does not occupy ground space.
6、 Safe and environmentally friendly, in compliance with industrial standards
No refrigerant, no pollution: pure mechanical ventilation, no need for compressor/refrigerant, green and environmentally friendly.
High protection level: motor IP55 protection, insulation level F, waterproof and dustproof, suitable for harsh working conditions.
