What really makes these worth buying is that they pull air non-stop without a single watt of electricity, which basically means you're ventilation costs to zero once installed. The 12-arc aerodynamic blades spin up to 800 RPM in a decent breeze and push out 800-1500 m³ of hot, stale air per hour depending on the model you pick.
It's built form 304 stainlss steel or aluminun alloy, so corrosion isn't an issue even in heavy, and the USA-imported UBC sealed bearings are completely enclosed—no grease, no maintenance for 15 years or so. Teh variable angle neck tube adjusts from 0 to 22.5°, letting you bolt it onto almost any roof pitch you'll encounter.
For US and EU buyers, we've got ISO 9001, CE, and RoHS certs on file, and COA and TDS come with every shipment so customs doesn't hold things up. Lead time is usually 20 days or so, but check stock before ordering large volumes—we typically have 500+ units ready.
Installation takes under 30 minutes on a standdard roof, which is faster than most turbine systems we've handled, and the design actually prevents rainwater ingress better than cheaper alternatives. One thing a lot of buyers don't think to ask: the operating temp range is -30°C to +80°C, so it works fine in cold storage warehouses or hot factory bays.
Anyway, it's not well suited for residential homes with very low roof pitches under 5 degrees—the airflow just isn't strong enough to justify the install effort there. Most commercial buyers go with the 400 series for larger buildings since it moves more air at lower wind speeds.
Yes, the variable angle installation allows adjustment from 0 to 22.5 degrees, so 15 degrees is no problem at all.
We supply ISO 9001, CE, and RoHS certificates. If you need specific copies for customs or project approval, just let us know.
Our MOQ is typically 50 units for the stainless steel model, but we can discuss smaller orders for sample testing.
Standard lead time is 15-20 working days after order confirmation, depending on stock levels at the time.
No, they're sealed bearings, so they're maintenance-free. Just install and they'll run smoothly for years.
