Keep Barns Below 22°C With Maintex Dairy Farm Fans
Above 22°C, heat stress slashes milk yields by 15%–25%. The Maintex EC72 high static pressure tunnel ventilation fan delivers 93,000 m³/h airflow. Armed with adjustable deflectors, these heavy-duty dairy farm fans drive a powerful 1200 FPM (>6 m/s) air curtain directly over feeding lanes. Even under 50Pa static pressure, one unit covers 360㎡ to fast-cool your herd, keeping cows feeding steadily and protecting your farm’s milk income.
Stop Barn Frame Resonance With Maintex Dairy Farm Fans
Ammonia and heavy dust build up on large dairy farm fans, causing imbalance and strong low-frequency vibration that shakes loose screws and deforms light steel barn structures. Maintex solves this problem. Every dairy ventilation fan is tested in our wind tunnel and built to strict dynamic balance standards. Our blades resist dust build-up and are easy to clean. You can run dozens of these dairy farm fans at the same time, and your barn structure stays solid and safe.
Custom Dairy Farm Fan Solution – Free 3D Drawings Available
Maintex owns a 45,000㎡ factory with over 1,200 workers and 225 patents. We support full customization for dairy farm fans, including size, voltage, and shaft. Running two production lines, we output 6,000 units monthly. Our 70-person R&D team provides free 2D and 3D drawings within 72 hours for your large dairy farm project. We update your order progress using real-time photos and videos, showing you exactly how your fans are built from start to finish.
“We never cut corners on barn ventilation. Every MAINTEX dairy farm fan is tested in a wind tunnel before leaving the factory, with real airflow and dynamic balance checked. We don’t do random sampling—every single dairy barn fan is 100% tested individually. With strict quality control, the fans delivered to your farm run at full power with strong cooling right away, no dead-on-arrival failures.”
To help you cut sea freight costs significantly, all our dairy farm fans are shipped as SKD (semi-knocked down) kits. Each part is clearly labeled with serial numbers, and we will provide you with a parts list. After receiving the cost-effective livestock fans, you can assemble them quickly by following the list and our installation videos. This not only saves shipping costs but also reduces labor expenses.
Summer heat is extremely risky. If your dairy ventilation system break down, the barn temperature can jump to 35°C in just a few hours, causing cows to die from heatstroke or even abort. MAINTEX helps you eliminate this risk completely. We include an extra 3% free spare parts with every order. If any part fails during peak electricity use, your team can fix it on the spot right away, without waiting weeks for international shipping.

Testimonials
“We met MAINTEX at the 2025 China Fan Expo while building our new dairy farm. Based on our barn dimensions, stall layout and summer heat conditions, James designed a professional air distribution plan for stalls and feed lines. After using MAINTEX dairy fans, our cows’ milk production increased by 10%. ”
John MillerDairy Farm Owner“Summer heat stress reduced our milk production by 15%. We needed dairy farm fans with strong airflow, higher energy efficiency and targeted air delivery. Then we chose MAINTEX EC72 fans with baffles that blow directly to free stalls and feed lanes, perfectly meeting our farm’s ventilation and cooling needs.”
Carlos RodriguezDairy Operations Manager“Our dairy farm fans run 24/7 in summer, leading to very high electricity costs. We finally achieved huge energy savings with MAINTEX BLDC direct-drive fans. This beltless direct-drive motor fan seemed expensive at first, but paid for itself in just 1.5 years. It’s maintenance-free, saving us time, labor and money.”
Robert TaylorLivestock Farm Manager
EC brushless motors deliver higher efficiency and precise stepless speed regulation, saving 20%-40% energy than traditional AC motors. As a high-efficiency dairy farm fan, it is perfect for 24/7 dairy barn ventilation, optimizes barn airflow efficiency and cuts long-term farm operation costs.
Dairy cows require stable and uniform wind speed for effective cow comfort ventilation. Blind large airflow cannot relieve heat stress well. Our dairy farm fan with baffle targeted airflow ensures precise barn heat dissipation without startling cows.
Definitely yes. The optimal mounting height for a dairy farm fan is 2.5–3.5 meters. Matched with our custom baffle design, the dairy farm fan delivers concentrated airflow to cow bodies, improving overall barn airflow efficiency and cooling effect.
Yes. Our BLDC direct-drive dairy farm fan supports external temperature and humidity sensors. It realizes automatic start-stop and speed adjustment, fully compatible with mainstream smart farm management systems.
Excessive noise disturbs cow rest and reduces milk yield. Our low vibration dairy farm fan runs stably with an ultra-quiet night breeze mode, ensuring long-term stable cow comfort and milk output.
Absolutely. No large-scale barn renovation is required. Our versatile dairy farm fan comes with personalized installation and custom barn airflow design service to upgrade ventilation and heat stress relief easily.
It makes a huge difference. For a dairy farm fan, a downward tilt of 15–25° is the best angle. It focuses airflow on cow free stalls and feed lanes, avoids wind waste, and maximizes barn cooling efficiency.
