Customization:
With a corrosion-resistant stainless steel body and blades, you can ensure long-lasting durability in harsh environments like coastal areas or industrial zones. Stainless steel outperforms traditional galvanized steel in resisting rust and corrosion, extending the product’s lifespan.
With self-spinning turbine blades that harness wind power, you can achieve continuous natural ventilation without electricity. This design eliminates the need for powered fans, reducing energy costs compared to traditional exhaust systems.
With a low-noise design and optimized blade structure, you can maintain a quiet indoor environment while efficiently exhausting stale air. Field tests show airflow efficiency comparable to electric fans at a fraction of the noise level.
With OEM/ODM support for size, shape, and material selection (e.g., coastal-grade stainless steel or lightweight aluminum), you can adapt the vent to residential, commercial, or industrial needs. This flexibility ensures compatibility with modern or traditional architectural designs.
With a 1-year warranty and robust stainless steel construction, you can trust reliable performance in extreme weather conditions. The polished finish also ensures seamless aesthetic integration with modern buildings.
The Unpowered Automatic Turbo Air Ventilation Fan is a roof-mounted, stainless steel centrifugal exhaust fan designed for natural ventilation. Its turbine-style blades and polished finish ensure efficient airflow, low noise operation, and seamless integration into modern architectural designs. With OEM/ODM support, it offers customizable solutions for diverse building requirements.

⭐⭐⭐⭐⭐ Jennifer Liu - Single-Family Homeowner
"Installed the Advanced Model on our attic roof six months ago, and it’s been a game-changer. No more stuffy, humid air in the summer—plus, it operates so quietly we don’t even notice it. The polished stainless steel looks sleek against our modern roofline. We live inland but still appreciate the corrosion resistance during rainy seasons. Zero energy cost is a huge win."Purchase Date: May 2024 | Usage Period: 8 months
⭐⭐⭐⭐⭐ David Reynolds - Warehouse Operations Manager
"We installed ten Pro Model turbine vents across our 40,000 sq ft warehouse in a coastal industrial zone. After six months of salt-laden winds and high humidity, the marine-grade stainless steel shows zero signs of rust. The airflow improvement has reduced internal temperatures by nearly 7°F, cutting our AC load significantly. Noise levels are impressively low—workers don’t even realize they’re there."Purchase Date: February 2025 | Usage Period: 5 months
⭐⭐⭐⭐☆ Maria Gonzalez - Restaurant Owner
"We replaced our old electric exhaust system with the Advanced Model turbine vent over our kitchen roof. Installation was straightforward, and the difference in air quality is noticeable—less grease buildup and no more lingering cooking odors. It doesn’t work as hard on windless days, but overall, the energy savings justify it. Only wish we’d known about the OEM customization earlier—we could’ve matched it to our building’s aesthetic better."Purchase Date: September 2024 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Thomas Bell - Facilities Supervisor
"Installed the Base Model on two low-slope roofs of our office complex. After five months, zero maintenance needed beyond a quick wipe-down. The <45 dB noise level keeps the outdoor patios peaceful—tenants have actually complimented how quiet the roof vents are. For a non-electric solution, the airflow is surprisingly effective, especially during afternoon breezes."Purchase Date: July 2024 | Usage Period: 8 months
⭐⭐⭐⭐⭐ Anita Patel - Coastal Property Contractor
"Used the Pro Model for a beachfront home renovation project. Salt spray and high humidity used to destroy standard vents within two years. This one? Looks brand new after seven months. The 32 dB operation is perfect for a quiet seaside retreat, and the automatic rotation handles shifting coastal winds flawlessly. Customized the diameter to 400mm to match the roof design—OEM support was responsive and professional."Purchase Date: April 2025 | Usage Period: 4 months

Linda Chen - Green Building HVAC Specialist
"In my 15 years of sustainable building design, passive ventilation solutions like this turbine vent are becoming essential. The combination of zero-energy operation, marine-grade corrosion resistance, and low-noise engineering makes the Pro Model ideal for both coastal homes and energy-conscious commercial projects. It outperforms solar-powered alternatives in consistent wind zones and avoids electrical complexity."
Marcus Tran - Commercial Architect
"I’ve specified the Advanced Model in three mixed-use developments. The polished finish integrates beautifully with modern metal roofing, and the ability to customize size and material gives architects real design flexibility. It’s rare to find a functional ventilation product that also enhances curb appeal."
