Why Chicken House Fan Matters for Heat Stress Control
High-CFM chicken house fans effectively control summer heat stress and flush out harmful ammonia. Built to be energy-saving, quiet, and rugged enough for 24/7 non-stop farm operation.
0.75HP to 3HP precise power matching for all farm sizes.
Genuine 39200 CFM maximum airflow tested under 0–75Pa resistance.
Premium PAG and stainless steel options withstand high-ammonia environments.
790mm to 1640mm standard opening fits new and old poultry barns.
Push-pull auto shutter tightly keeps outside wind and dust out.
Supports stepless variable speed and RS485 protocols for smart barn automation.
Class B insulation built for 24/7 non-stop continuous farm operation.
Flexible 3 or 6 blade configurations to match custom barn ventilation layouts.
Anti-Seize Chicken House Fan Shutters With Nylon-POM Bushings
Heavy-duty chicken house fans often suffer from jamming due to accumulated feathers, dust, and barn moisture. Our automatic shutters discard easily rusted metal shafts, utilizing high-strength Nylon and POM self-lubricating resin bushings to avoid rust and linkage sticking without oiling. This low-friction design can fully open shutters to 90 degrees within 0.1 seconds to achieve maximum CFM airflow output. When stopped, the mechanical lock structure guarantees 100% sealing to effectively block winter cold drafts and lower annual heating costs.
The Advantage Of EC Direct Drive Chicken House Fans
Long-term belt fans stretch and slip. This problem loses 10% to 20% CFM airflow, causes livestock poultry heat stress, and traps harmful ammonia inside your barns. Also, paying local workers to tighten and change old belts cuts your farm profit. We solve this. Our factory supplies budget-friendly, belt-free EC direct-drive chicken house fans. They provide stable air volume, require zero post-purchase maintenance, and help you control barn environment without the expensive market price tags.

Full customization is available for livestock exhaust fans, including size, material, voltage, speed, torque, shaft, and logo.
In your closed, long broiler houses, heat and moisture build up very fast. Our 50″ and 54″ EC chicken house fan is designed for high-speed tunnel ventilation to pull heat out quickly. Running at full capacity, the wind-chill effect is obvious, effectively lowering your birds’ perceived temperature. Built with high-efficiency EC permanent magnet motors, this chicken house fan delivers stronger airflow at the same power, saving your farm 30% on summer electricity bills per unit.
High-density cage houses have poor airflow, allowing ammonia and CO₂ to build up and hurt egg production. Our FRP anti-corrosion chicken house fan is built to withstand this harsh, corrosive environment. Paired with 36″ low-noise side wall fans, this chicken house fan maintains stable air quality throughout the house. Quiet operation keeps hens calm and stress-free, ensuring consistent laying performance.
Chicks and embryos are super sensitive—direct cold drafts are a death sentence for them. Our 24″ and 36″ EC variable-speed fans allow for precise airflow control, keeping the temperature rock-steady. They run ultra-quietly, too, so your chicks don’t get stressed out. When the environment stays stable, your hatch rates and survival numbers will speak for themselves.
When upgrading old chicken houses, you need a chicken house fan that fits directly to save time, labor, and cost. Our 50″ AC galvanized chicken house fan comes in standard universal sizes for easy drop-in replacement. It matches your existing wall openings perfectly, with no extra construction needed. This cost-effective chicken house fan delivers strong exhaust, letting you upgrade ventilation quickly with minimal labor.

Testimonials
“We sell poultry fans in many different countries, so we need a supplier who can handle all kinds of voltage specs. MAINTEX is great for this—they cover everything from 110V to 460V (50Hz/60Hz). Plus, they handle the custom branding and neutral packing perfectly, and they actually respect our exclusive territory. It’s a very smooth business partnership for our distribution channels.”
Carlos MendozaSourcing Manager, Mexico“We always import chicken house fans in SKD form and assemble them locally here in the Philippines. It’s extremely hot and humid in summer, but the MAINTEX motors in our chicken house fan units have run non-stop for two years with zero problems. Airflow is strong and stable, helping reduce poultry heat stress and clear ammonia inside the barn effectively. “
Benjamin TanOperations Director, Philippines“Every time a batch of chickens leaves, we wash the whole barn with high-pressure water. The cheap exhaust fans we used before got rusty in three months and burned out motors in six months, so we switched to the MAINTEX EC54 chicken house fan. I was a little worried at first, but after one year of frequent flushing, this chicken house fan never rusts at all. It’s totally worth the money.”
Derek EvansFarm Owner, Australia“Many factories give low quotes but use very cheap packaging. After long sea shipping, the shutters are often bent and ruined. MAINTEX is an SGS-verified real factory with very solid packaging. They always send photos to confirm before shipment, so we feel safe to do long-term chicken house fan business with them.”
Marek KowalskiEquipment Distributor, Poland
We support all global mainstream specs: 110V, 220V, 230V, 380V, 460V, in both 50Hz and 60Hz. Just tell us your local power standard, and we’ll customize the wiring to fit your barn automation system perfectly.
Absolutely not. A frequency mismatch makes the motor run at abnormal speed, overheat severely and burn out quickly. It will also mess up your whole barn ventilation. Please confirm your local frequency before ordering, and we’ll pre-set the motor correctly for you.
If you use high-pressure water to wash your barn, I recommend going with the IP66 version for full dust and water sealing. IP55 is only splash-proof; it’s not enough for the high-humidity, ammonia-heavy conditions of a poultry house.
It’s simple. Our fans range from 24 inch to 54 inch with standard mounting sizes, designed for direct replacement. No wall breaking or extra construction needed. Just send us your wall opening dimension, and we’ll match a fan that fits perfectly.
Simple formula: Barn volume × air changes per hour = required CFM. But static pressure and poultry density also make a big difference — no need to guess. Send us your barn layout, and our team will calculate and send you a free ventilation design solution.
Yes, you can. We use standard, universal mounting designs—no proprietary parts here. If you ever need to replace a motor years down the line, you won’t have to hunt for custom parts from us. You can just grab a standard industrial motor from your local supplier and bolt it right on. We want to make your maintenance easy, not tie you into exclusive parts.
