CHARACTERISTICS
- · Wind-powered natural drive: Turbine is driven by natural wind and rising hot air thrust, zero power consumption, no electrical wiring required.
- · Full stainless steel body: Precisely manufactured with stainless steel, excellent rust, corrosion and weather resistance for long-term outdoor roof installation.
- · High-efficiency turbine structure: Curved streamlined blades, starts at low wind speed with high exhaust efficiency; stable rotation and steady airflow.
- · 24/7 automatic operation: Uninterrupted automatic exhaust around the clock, continuously expels indoor heat, moisture, dust and odor.
- · Ultra-quiet operation: No motor, no mechanical friction, extremely low operating noise and no noise pollution.
- · Waterproof mounting base: Equipped with mounting base with excellent sealing, prevents roof rainwater leakage after installation.
Applicable scenarios
- · Industrial buildings: Roof ventilation, heat and moisture removal for steel structure workshops, warehouses and storage facilities.
- · Agricultural sites: Ventilation, dehumidification and deodorization for livestock houses, greenhouses and grain silos.
- · Civil & commercial: Roof exhaust for attics, basements, shops, kitchens and bathrooms to improve indoor air quality.
- · Special scenarios: Natural ventilation for power-free areas and explosion-proof sites, zero electrical risk.
Advantages
- · Zero operating cost: Fully wind-driven, no electricity expense, remarkable economic benefit for long-term use.
- · Energy-saving & low-carbon: No energy consumption, no carbon emission, complies with green building and environmental policies.
- · Durable & maintenance-free: All-stainless steel structure, no motor or wearing parts, long service life with almost no daily maintenance.
- · Quick & easy installation: Fixed directly after roof opening, no circuit layout required, simple and fast construction.
- · Stable continuous ventilation: All-day uninterrupted exhaust effectively reduces indoor temperature, removes moisture and improves muggy environment.
