PAG Fiberglass Fan Blade | Low Wind Resistance & Deformation-Proof
We use PAG fiberglass blades for all MAINTEX hog barn fans. They are tough and deformation-resistant, and will not crack under extreme temperatures. Every single blade undergoes dynamic balance testing before assembly to reduce vibration. The aerodynamically optimized blade angles greatly cut wind resistance and boost overall CFM airflow. With large air volume and low noise, it delivers efficient ventilation for your pig barn all year round.

Professional Hog Barn Fan Comparison | EC & AC Ventilation Fans
Budget VS High-Efficiency Pig Farm Ventilation Solutions。
Traditional AC hog barn fans feature simple structure, low cost and universal spare parts with low maintenance costs. Perfect for budget pig farms, ordinary finishing barns and basic ventilation for small and medium farms. However, they require an external inverter for speed control, adding extra investment. AC fans consume more power at low speeds, generate high starting current that impacts your farm circuit, and run with louder noise and greater vibration with poor stability.
MAINTEX IE5 high-efficiency EC hog barn fans save you up to 30% electricity bills for 24/7 continuous farm operation. Built-in 0–10V stepless speed control requires no external inverter and supports automatic speed adjustment by connecting to your farm’s smart environmental control system. With soft start, low vibration and low noise, the fans feature excellent moisture and corrosion resistance, adapting to frequent disinfection and humid farm environments with ultra-low failure rates. Ideal for sow barns, breeding barns, isolation barns and large intelligent farming projects.

Testimonials
“High ammonia and weak airflow in our finisher barns were constant headaches. Then we found MAINTEX. The hog barn fans we bought solved everything: ammonia stays below 20ppm, airflow decay is less than 30% even with ducts, and barn temperature holds steady around 20°C. Our hogs no longer show respiratory issues, and feed conversion has improved noticeably. ”
Carlos MendezOperations Director, 2,400-Sow Farm“We all know the ideal nursery conditions: 28–32°C, 60–80% humidity, and 0.2–0.3m/s airspeed at 1m height. Go beyond that, and you get cold stress, poor weight gain, and sickness. My old AC fans could never maintain this. After seeing MAINTEX EC fans at a trade show, I decided to test 5 units. They exceeded my expectations for airflow and energy efficiency. ”
Anna WeberNursery Manager“Many Chinese suppliers inflate airflow ratings and make noisy fans. I tried MAINTEX with low expectations, even ordering just one unit—and they accepted it. Their EC fans support 0-10V, PWM, and RS485 control signals. The EC36-high power model delivers exactly the labeled airflow at 0/25/50/100/150Pa. Noise stays around 70dB, so hogs eat and rest without disturbance. ”

0-30Pa for open straight exhaust barns, 30-80Pa for barns with filters, 80-150Pa for wet curtain, long duct and deodorization systems. Our fans keep airflow decay below 30% under high static pressure.
Ammonia over 20ppm irritates pig respiratory tracts, causing coughing, respiratory diseases and reduced feed conversion rate. Stable negative pressure ventilation effectively maintains safe ammonia levels for healthier hog growth.
Finishing barns suit 18-25℃, nursery barns require 28-32℃, humidity keeps 60%-80%. Proper ventilation avoids high humidity bacteria growth, low humidity dust and pig cold stress.
Fiberglass housing resists ammonia corrosion, disinfectant damage and aging. It fits harsh humid pig farm environments, avoids rust and deformation, ensuring longer service life and stable ventilation performance.
Maintain 0.2-0.3m/s safe 1-meter ground wind speed. Variable-speed EC fans deliver a stable, low-turbulence airflow, preventing excessive wind speed, cold stress and pig weight loss all year round.
All our CFM figures are lab-tested at 0/25/50/100/150Pa with no inflated zero‑pressure ratings. With less airflow loss, you get far better ventilation on your actual pig farm.
